You may remember the discussion on the LTRU and IETF-languages mailing
lists about marketing the standard, having a Web site and so on. At
this time, I had set up a small site http://ltru.generic-nic.net/ to
show what could be done.=20

Now, I'm decided to go a step further and I purchased langtag.net for
that purpose (and I am of course ready to transfer it for free to any
other holder, should the WG think it is better.)

I would like http://www.langtag.net/ to be "blessed" as a reference
Web site for the language tag activity at IETF and noticed for that at
http://www.ietf.org/html.charters/ltru-charter.html.

The difference between the old site and the new one are:

* a better domain name :-)

* a bit more content (such as the syndication feed for the registry),

* the ability to give write-access to people other than me.

[co-chair hat on]

Dear WG members,

Please provide input (agreement or disagreement) on Stephane's proposal
that the WG chairs ask the Area Director to add a link from the
LTRU WG charter to http://www.langtag.net/.

[co-chair hat off]
I think that this site provides very useful additional information
for helping users of language tags, and I therefore personally
support this request.

Regards,    Martin.

Both the "how" and the "who" should be discussed among us, although
the choices for "how" are limited as long as I manage the technical
stuff :-) If an other hosting seems better, we can move the site
elsewhere.

How? Currently, the pages are written in XML, transformed to XHTML by
a XSLT script. The automatic pages (like the registries in various
formats) are automatically and nightly produced. More converters are
welcome.

The files are in a Subversion repository and I'm willing to open
access to the module, as soon as I'll have learned how to grant access
to a Subversion module but not to the others (which should not be too
complicated). Anonymous read-only access seems a good idea, too.

Who? We should discuss it. My personal opinion is that it should be
limited to people who want to commit on the task (volunteers
welcome). One-line patches and typo fixes can be sent by email to the
webmaster.

If the co-chairs don't have any problem with it, then I support it.

[chair hat on]

Two points:

- We can probably not totally avoid discussion of details of this
  Web site here on this list, but I'd like to limit to an absolute
  minimum.

- For people who might be affraid about the details, please note
  that if at any point the WG thinks that this Web site doesn't
  help LTRU anymore, we are free to remove the link from our
  charter page at any time.

Regards,    Martin.

...

Although there are obviously some operational details still being
worked out in this thread, as co-chair I have no problem with
the idea of requesting the addition of a link to additional information
to our WG web page.

For instance, people who are specially interested in this Web site and
eager to participate can contact me off-list and we can discuss the
details together without bothering the WG with Subversion
vs. Mercurial or HTTP's Accept-language vs. cookies :-)

I thought I would pass along the following post by Dave Crocker from the 
IETF main list, as I think it applies to our work as well.  More than a few 
of our ideas and proposals have gotten bogged down in objections of the form 
"someone might misunderstand this" or "someone might abuse this."  These are 
often valid arguments, but they need to be put into perspective and weighed 
against the benefits.

I note that this is what most people probably thought it meant in the
first place. It is the only meaning that makes any sense and I cheer
this clarification.

Yes, the "meaning" of the 'mis' code is "narrowed" by additions of codes
(assuming that codes added alway cover additional languages and not just
finer gradations of existing ones, a case that isn't that uncommon)---if
one takes a collective view of all content in the universe and assigns
it a language tag today.

But the definition of the 'mis' code is exactly what 4646bis is=20
currently set to say: stuff whose language is known (not 'und') but=20
which you can't otherwise tag, either because no code is available or=20
(more likely) the code isn't available to your application.

The reasons for using the 'mis' code are limited and I suspect that we
hardly ever see it in the wild nor will we in the future. As a tag it=20
only has meaning in the context of a fixed set of content and it has=20
essentially no meaning in language ranges except when working with sets=20
that are known to use it.

As for deprecation, I think this is such a perverse interpretation of=20
the meaning of "narrows" that I can't see following through on it with=20
deprecation. Let's fix our draft text and move along. Currently the=20
draft for the next version of BCP 47 informs users why the subtag has=20
limited value and say that it SHOULD NOT be used. That's strong enough.

I agree with Addison completely.  Unless Mark or someone else can find 
real-world examples of "mis" being used for a language that has its own ISO 
639 code element and/or language tag -- not hypothetical examples or 
extrapolations or theory -- there is no "narrowing" argument.  We have gone 
to great lengths to assert that "mis" isn't like the other collection codes, 
and now the JAC has made a decision which reflects that assertion.  Let's 
make the appropriate change to the Registry and be done with it.

"Because no code is available" is supported by the definition.
Because "the code isn't available to your application" is not, in my opinion.

[re-sending to appropriate list]


+1 to what Doug said. The name has changed; the intended semantic has not.

I think we'd all agree it's not a good idea for anybody to use 'mis' in the=
 context of 4646bis. But I don't see why we need to do more than recommend =
against its use except as a last resort: if an informed user feels that it'=
s really what they need to do because they believe they know the language o=
f their content and believe there is no subtag for it in the LSTR and feel =
they need to declare that condition, that should be their prerogative.

I would make some minor changes to the current text: from

"The 'mis' (Miscellaneous) primary language subtag is derived from a collec=
tive code and is used to identify linguistic content whose language is know=
n but cannot otherwise be identified. It is commonly used when the range of=
 language tags is constrained or for languages not otherwise categorized...=
 "

To

"The 'mis' (Uncoded languages) primary language subtag is used to declare t=
hat linguistic content is in a known language but that this language cannot=
 be indicated. It is typically used when the range of language tags support=
ed in a given application context is constrained or for languages not other=
wise categorized... "

(I particular think we should avoid "commonly used": we don't want to sugge=
st to the reader that it is commonly used.

I agree with Peter here.  The intent of this code element has not changed,
but the new name reflects the intent much better than the old name did.  Th=
e
code element was always inherently unstable.

Strongly, strongly opposed.

3) Deprecate "mis", and use "und" to mean "the language of this content is
undetermined" as it has always meant.

4) Don't deprecate "mis", and use "und" to mean "the language of this
content is undetermined" as it has always meant.

Please stop trying to postulate a relationship between "mis" and "und" that
isn't there.  They have always meant two totally different things.

I agree with Peter and Doug.  However, I would change Peter's proposed text
to read as follows:

 "The 'mis' (Uncoded languages) primary language subtag MAY be used when
there is an identified need to declare that linguistic content is in a known
language that is not currently supported within the Registry by any other
language subtag or when the range of language tags supported in a given
application are constrained. "

...

I disagree with the phrase "or when the range of language tags supported in
a given application are constrained."  If the application knows what language
it is, it should use the correct tag, if one exists.  If the application doesn't
know what language is in use, "und" would be correct.

I also suggest that we consider what RFC 2119 says regarding "MAY" versus
"SHOULD NOT" qualifiers for features:

4. SHOULD NOT   This phrase, or the phrase "NOT RECOMMENDED" mean that
   there may exist valid reasons in particular circumstances when the
   particular behavior is acceptable or even useful, but the full
   implications should be understood and the case carefully weighed
   before implementing any behavior described with this label.

5. MAY   This word, or the adjective "OPTIONAL", mean that an item is
   truly optional.  One vendor may choose to include the item because a
   particular marketplace requires it or because the vendor feels that
   it enhances the product while another vendor may omit the same item.
   An implementation which does not include a particular option MUST be
   prepared to interoperate with another implementation which does
   include the option, though perhaps with reduced functionality. In the
   same vein an implementation which does include a particular option
   MUST be prepared to interoperate with another implementation which
   does not include the option (except, of course, for the feature the
   option provides.)

Hoi,
Standards have a tendency to lag behind what is accepted to be true. When a
standard does not acknowledge a specific language of linguistic entity yet
because it is not in that version of the standard, a tag could be not
available because a specific version of standard has not been ratified yet.
Thanks,
     Gerard

Hoi,<br>Standards have a tendency to lag behind what is accepted to be true. When a standard does not acknowledge a specific language of linguistic entity yet because it is not in that version of the standard, a tag could be not available because a specific version of standard has not been ratified yet.

This is the *sole* case where "mis" would be appropriate,

However, I would also argue that if I were a field linguist collecting data on
previously unknown languages (the most likely scenario in which one could legitimately
encounter a need for "mis") that I'd be better off using private-use subtags as
an *interim* measure for my data.  With private-use subtags I'd know which was which.
With "mis" I'd have thrown everything into one basket.

The meaning of prefix really should be clear in the text. When John says 
"let's fix this bug", I presume he means that we should explicitly say 
that all prefix subtags must appear to the left of the variant in question.

To that, I can say: +1

Copying ltru, where this discussion should continue.

Randy:

MARC is an application context -- an application of language tags, not an a=
pplication in the sense of a piece software. In that application context, o=
nly IDs from 639-2 can be used: that is a constraint on the range of langua=
ge tags supported in that application context. Whether a user or a software=
 process is assigning tags, the options are not necessarily binary, as you =
suggest: in that application context it is entirely possible for the langua=
ge of given content to be known but not to be within the restricted set per=
mitted by MARC.

...

I disagree with the phrase "or when the range of language tags supported in
a given application are constrained."  If the application knows what langua=
ge
it is, it should use the correct tag, if one exists.  If the application do=
esn't
know what language is in use, "und" would be correct.

I also suggest that we consider what RFC 2119 says regarding "MAY" versus
"SHOULD NOT" qualifiers for features:

4. SHOULD NOT   This phrase, or the phrase "NOT RECOMMENDED" mean that
   there may exist valid reasons in particular circumstances when the
   particular behavior is acceptable or even useful, but the full
   implications should be understood and the case carefully weighed
   before implementing any behavior described with this label.

5. MAY   This word, or the adjective "OPTIONAL", mean that an item is
   truly optional.  One vendor may choose to include the item because a
   particular marketplace requires it or because the vendor feels that
   it enhances the product while another vendor may omit the same item.
   An implementation which does not include a particular option MUST be
   prepared to interoperate with another implementation which does
   include the option, though perhaps with reduced functionality. In the
   same vein an implementation which does include a particular option
   MUST be prepared to interoperate with another implementation which
   does not include the option (except, of course, for the feature the
   option provides.)

What you say wrt private-use subtags being better than 'mis' is true if the=
 application context is a linguist collecting field data. It may not be tru=
e in all application contexts, however. In particular, it is NOT the practi=
ce in MARC, nor would it be in the interest of that standard to start defin=
ing private-use IDs for use in MARC records. (It may make sense for a local=
 implementation of MARC, however.)

This is the *sole* case where "mis" would be appropriate,

However, I would also argue that if I were a field linguist collecting data=
 on
previously unknown languages (the most likely scenario in which one could l=
egitimately
encounter a need for "mis") that I'd be better off using private-use subtag=
s as
an *interim* measure for my data.  With private-use subtags I'd know which =
was which.
With "mis" I'd have thrown everything into one basket.

As such, I'd argue that these constraints mean it isn't an application of BCP 47.

These things might be called tags, and they might even be a subset of the
set of strings that are well-formed, valid BCP 47 tags, but this is *NOT* an
application of BCP 47, and, consequently, is not our problem.

That's nice in theory. But some applications use a subset of tags (I 
used the MARC21 example in the text) and then transmit them through 
another system (where the larger range of RFC 4646 is available). Those 
systems only know that the content is 'mis' (because it is tagged that 
way) and not what the miscellaneous language happens to be.

We don't define what subtags applications are capable of supporting or 
required to support elsewhere. We should focus on providing appropriate 
guidance (which is not to use the subtag). I note that Peter's use of 
MAY doesn't reflect the current draft.

I propose that we modify the draft to say the following. Please note: 
the paragraph format is consistent with the other items in that section. 
I think that folks should glance at that text when proposing edits.

--
The 'mis' (Uncoded) primary language subtag is used to identify 
linguistic content whose language is known but cannot otherwise be 
identified. It is intended for use when the range of language tags is 
constrained or for languages not otherwise categorized. It SHOULD NOT be 
used except when other means of identifying the language are not 
available. For example, a library application might be limited to the 
set of subtags defined for use by the [MARC21] standard. The 'mis' 
subtag might be used by this application for languages not included in 
that set.

This is an interworking problem, where data from a non-BCP 47 environment
needs to travel through a BCP 47 one.  In this particular case, things
work out.  But as for the proposed text...

...
> The 'mis' (Uncoded) primary language subtag is used to identify

The phrase "known but cannot otherwise be identified" is a bit obscure.
I suggest replacing it with "known but for which no subtag has been defined."

> It is intended for use when the range of language tags is 
> constrained or for languages not otherwise categorized.

This only makes sense if we somehow want to shoehorn MARC into being
BCP 47 compliant.  I propose deleting this sentence.

Minor edit: I think the would be much easier to read if worded:
 It SHOULD NOT be used when other means of identifying the language are available.

> For example, a library application might be limited to the 
> set of subtags defined for use by the [MARC21] standard. The 'mis'

I think this is not a good example of a BCP 47 use of "mis".

Although I think it's quite reasonable and fortunate that MARC data
could traverse a BCP 47 environment unharmed (and this falls under the
"SHOULD NOT" rules of RFC 2119), I do *not* think we should stretch things
to where we'd claim that MARC is "compliant".  It's just a happy circumstance
that data encoded under the MARC regime is still meaningful when interpreted
under BCP 47 rules, unless tagged with "mis".

You appear to be assuming that for something to qualify as "an application =
of BCP 47" it must support all tags defined by BCP 47.

I would certainly agree that a BCP 47-conformant parser must fully support =
the syntax that's defined, and for a BCP-47 validator to validate all and o=
nly tags that are defined in relation to a given snapshot of the registry.

But I see no reason why a higher-level protocol cannot restrict the set of =
tags it accepts and still be considered "an application of BCP 47". I would=
n't be surprised if was actually common for people to create higher-level p=
rotocols that normatively reference BCP 47 but that define some subset of t=
ags that are permitted. What is the problem in saying those are "applicatio=
ns of BCP 47"? It would certainly be getting applied in those cases.

As such, I'd argue that these constraints mean it isn't an application of B=

These things might be called tags, and they might even be a subset of the
set of strings that are well-formed, valid BCP 47 tags, but this is *NOT* a=
n
application of BCP 47, and, consequently, is not our problem.

On this issue...

I do note that the section on variants currently says:

--
Variant subtag records in the language subtag registry MAY include one 
or more 'Prefix' fields, which indicate the language tag or tags that 
would make a suitable prefix (with other subtags, as appropriate) in 
forming a language tag with the variant.
--

The word "suitable prefix" at least conveys some intention for the 
subtags to fall to the left of the variant in question.

I modified this to say:

--
Variant subtag records in the language subtag registry MAY include one 
or more 'Prefix' fields. The 'Prefix' indicates the language tag or tags 
that would make a suitable prefix (with other subtags, as appropriate) 
in forming a language tag with the variant. That is, each of the subtags 
in the prefix MUST appear before the variant in a valid tag.
--

Note here the use of the word 'valid' in conjunction with MUST. We 
required the prefix to be present (using extended language range rules), 
but didn't make the position of the subtags clear in the section on 
classes of conformance. I added the [[[marked sentence]]] in this 
snippet from that section:

--
For each subtag that has a 'Prefix' field in the registry, the Prefix 
matches the language tag using <xref target="RFC4647">Extended 
Filtering</xref>. That is, each subtag in the Prefix is present in the 
tag  and in the same order. [[[Furthermore, all of the Prefix's subtags 
MUST appear before the subtag.]]]
--


I also modified the text in extended language subtag to say:

--
Each extended language subtag MUST only be used in tag immediately 
following the exact sequence of subtags that appears in the 'Prefix' 
field in its registry record.
--

In the section on registry format, we had:

--
Prefix's field-body contains a language tag with which this subtag MAY 
be used to form a new language tag, perhaps with other subtags as well. 
This field MUST only appear in records whose 'Type' field-body is 
'variant' or 'extlang'.
--

I changed this to read:

--
Prefix's field-body contains a language tag with which this subtag MAY 
be used to form a new language tag, perhaps with other subtags as well. 
The Prefix's subtags MUST appear before the subtag for the tag to be 
considered valid. This field MUST only appear in records whose 'Type' 
field-body is 'variant' or 'extlang'.
--

In the subsection on Prefix I made an edit to say:

--
The field-body of the 'Prefix' field consists of an extended language 
range whose subtags are appropriate to use with this subtag: each of the 
subtags in one of the subtag's Prefix fields MUST appear before the 
variant in a valid tag.
--

Note again the use of the term 'valid' corresponds to MUST appropriately.

Comments?

But MARC uses the three-character 639-2 tags for the most common

Let's not get too hung up on MARC as an example. It serves as an example of=
 something that limits the set of tags, not specifically as an application =
of BCP 47, which it does not claim to be (and, as Karen points out, is not)=
.

Suppose a corpus that has content in a number of languages with primary foc=
us on particular languages, but in which the criteria for inclusion of reco=
rds is based not solely on language, with the result that some records are =
not in one of the languages of primary focus. Suppose that content is recor=
ded in an XML language, with language declared using xml:lang. Because XML =
is used, that would be an application of BCP 47 according to my understandi=
ng of conventional uses of "application of". The policy for that corpus, ho=
wever, might well be to use 'mis' for any records not in some specified lis=
t of languages. IMO, that particular fact should not nullify describing tha=
t system as "an application of BCP 47".

But MARC uses the three-character 639-2 tags for the most common languages,=
 right? If so, that is not a restriction, it's a violation.

RE: [Ltru] RE: ISO 639-2 decision: "mis"







You appear to be assuming that for something to qualify as "an application =
of BCP 47" it must support all tags defined by BCP 47.

I would certainly agree that a BCP 47-conformant parser must fully support =
the syntax that's defined, and for a BCP-47 validator to validate all and o=
nly tags that are defined in relation to a given snapshot of the registry.

But I see no reason why a higher-level protocol cannot restrict the set of =
tags it accepts and still be considered "an application of BCP 47". I would=
n't be surprised if was actually common for people to create higher-level p=
rotocols that normatively reference BCP 47 but that define some subset of t=
ags that are permitted. What is the problem in saying those are "applicatio=
ns of BCP 47"? It would certainly be getting applied in those cases.

As such, I'd argue that these constraints mean it isn't an application of B=

These things might be called tags, and they might even be a subset of the
set of strings that are well-formed, valid BCP 47 tags, but this is *NOT* a=
n
application of BCP 47, and, consequently, is not our problem.

<tt>&gt; MARC is an application context -- an application of language tags,=
 not
an</tt><br>
<tt>&gt; application in the sense of a piece software. In that application
context, only</tt><br>
<tt>&gt; IDs from 639-2 can be used: that is a constraint on the range of
language tags</tt><br>
<tt>&gt; supported in that application context.</tt><br>
<br>
<tt>As such, I'd argue that these constraints mean it isn't an application =
of
BCP 47.</tt><br>
<br>
<tt>&gt; Whether a user or a software process is assigning tags, the option=
s
are not</tt><br>
<tt>&gt; necessarily binary, as you suggest: in that application context it=
 is entirely
possible</tt><br>
<tt>&gt; for the language of given content to be known but not to be within=
 the
restricted set</tt><br>
<tt>&gt; permitted by MARC.</tt><br>
<br>
<tt>These things might be called tags, and they might even be a subset of t=
he</tt><br>
<tt>set of strings that are well-formed, valid BCP 47 tags, but this is *NO=
T*
an</tt><br>
<tt>application of BCP 47, and, consequently, is not our problem.</tt><br>

So far so good.

This is where we differ.  While the syntax is still ok, the semantic is changed
past any hope of interoperability.  (Rather like that classic paper on Recoverability
Under Deletion.  :-)  It would rather be like using "sw" to mean "Swiss German"
rather than Swahili.  I'd consider that an abuse, rather than an application, of the BCP.

I don't get that at all. Every user of that system, which may well be publi=
c, would understand by the policy for that system, what to expect. The sema=
ntics of 'mis' would be clearly documented both in ISO 639 and in the LSTR,=
 and the usage would be consistent with the documented semantics. If any da=
ta is exported outside that system, then there would be some semantic loss =
because the context is lost, but that is part of the documented contract ar=
ound 'mis' -- and why users need to understand its shortcomings, so also wh=
y users would probably be warned against exporting data.

The only issue here is the inherent instability and shortcomings of 'mis'. =
I don't see any abuse of BCP 47. There is nothing whatsoever like using "sw=
" to mean 'Swiss German'.

With the given recent change for ISO 639 w.r.t. 'mis', 'mis'
is not applicable, when using BCP 47 tags, in such cases
either, due to inherent instability of 'mis' that result from
the recent change. 'und' is still applicable (but has admittedly
a different intension).

Agreed.

Which "documented contract"?

This is making the case for using "MUST NOT" rather than "SHOULD NOT".

Yes, it is in that permitting the tag to be used for languages for which tags
already exist is in direct contradiction to its description.

Double nots are not good :-)

I propose:

"It should only be used when other means of identifying the language are
unavailable."

I expect the ISO 639 RAs will be providing a usage note wrt 'mis' explainin=

IMO, this is in the same line as people using a tag like "en-Latn": we say =
"the script subtag SHOULD be omitted" in such cases, but not that they MUST=

The issue here is evaluating "languages for which tags already exist". You'=

l can restrict the contents of the LSTR it permits and that it can also det=

Yes.  If an application lacks the knowledge to make that determination, 
"und" would be the correct choice.

As such, it would no longer support BCP 47.
At a minimum, I would argue that a protocol that claims to support BCP 47
must be able to carry all valid tags, and should probably be able to carry
all well-formed tags.  Anything less is merely "based on" BCP 47.

This is simply not interoperable, as you've already explained.

If someone decides a subset of BCP 47 is appropriate to their needs,
that is fine, just as long as they don't claim to sully support BCP 47.
Taken to absurdity, if my protocol offers a choice limited to "en" and "mis", 
should I be able to claim to support BCP 47?  In any case, I'd really hate
 to have this WG go down the path of defining standardized
"profiles" of BCP 47 unless there were a *huge* benefit to doing so.

Just like the "adapted subset" of ASN.1 used in SMI MIB modules, at
some point one has to admit that the subsetting and adaptation can result
in a quite different beast from what one might have started with.

Even treated as you proposed, 'mis' is inherently unstable wrt extension (a=
nd always has been). That is part of the contract taken on by anybody who c=
hooses to use it with any profile of language tags that is open to change. =
You say that's not interoperable; I say it's interoperable given appropriat=
ely low expectations of the usefulness of 'mis' in interchange.

Absolute agreement. I have never suggested we should define standardized "p=
rofiles". If a consuming protocol wishes to do so, that's entirely up to th=
em -- we certainly should not do it for them.

There's a difference between "fully supporting" BCP 47 and being compliant 
with BCP 47. I don't think there's any organization that has a real-life 
use for fully supporting BCP 47. These codes are frequently used in 
databases; if a developer limits the size of that field such that the most 
granular private use tag imaginable does not fit the space allocated, you 
consider that to an implementation "based on" BCP 47 even if all tags in 
the system are valid?

I don't think what you suggest is a useful or realistic way of looking at 
this. If I only need en, fr, de, and it, I think that's fully compliant 
with BCP 47. Must I support gsw-Hant-BV-x-chicago-mwbstr14-spoken to claim 
to be aligned with BCP 47?

RFC 4646 says support for a maximum of at least 33 characters is a MUST,
42 characters is a SHOULD.  Anything less is not BCP 47.

If someone designs a protocol, and it can only handle the language tags
en, fr, de, and it, that protocol, in my judgement, would not be compliant
with BCP 47.  This doesn't say anything about the tags that a particular
application using that protocol might *generate*.  I'm just saying that it
must be able to cope with receiving valid tags of up to 33 characters in
length.

I'm urging folks to think about where this specification sits in the "food chain".
It specifies an element that is used by other protocols.  If other protocols
can claim to use this specification, without actually being able to carry the
full range of values, there will be little value to having this specification or to
claiming to support it.  It'd be like claiming to support ASCII, but not permitting
use of the letter "Z".  I fully recognize that for good historical reasons there
will be protocols that are restricted to a subset.  However, I'd strongly urge
against claiming that such protocols "supported" or were "aligned with",
much less "conformant with" BCP 47.

I think part of the disconnect is that some have been thinking about databases,
rather than protocols.

Randy

That assumes that some codes are actively removed (not just
deprecated), for some language (or "language collection") that
actually exits. I doubt that will happen in ISO 639, though that
make happen in some application (like MARC) that pick up just a
subset of the ISO 639 tags.

MARC is just one application of 639, not THE application of 639.

Note also that you erroneously conflate two issues here:

1) Which languages are covered by 'mis' in the MARC application
   of 639, and
2) which of those languages that are explicitly mentioned in
   some list for MARC.

For the first one, that is most likely quite a lot of languages
(every language not having a code in MARC).

For the second one, it is just a matter of making explicit
a few of the languages covered by 'mis' in the MARC application.
You can make explicit quite a few more languages without changing
which languages are covered by 'mis' in the MARC application
(i.e. a change of no actual consequence).

No, it is for use when the language *has* not been identified.
Not at all the same as *cannot* be identified.

> That is a quite different concept than to say
> I know what language it is but there is no coded identifier for the
> language.

Yes, but from a coverage point of view, 'und' covers all languages
as well as 'zxx' and 'mul'. Not a far cry from what 'mis' used to
cover (namely all (natural, and natural-like) languages). And you
have not given any other option than 'und' (and private use codes)
as a replacement for what 'mis' used to cover (as a collection).

With this change you have turned a fairly logical system into one
that has an illogical and quite unnecessary exception. I fail to
see why that would be a good thing.

And with this change, an application of ISO 639 that requires
stability over time, like IEFT language tags, unstable tags
(w.r.t. coverage of languages) are highly detrimental.

With the "old mis" one could correctly apply 'mis' as a language
code for any language (though one should apply a more specific
code if one is "available"), and stably so. With the "new mis" that
is not possible.

IIUC, for all other collections there are plans do make a
clarification (not a change) in the opposite direction,
removing the confusing (but in ISO 639 context, meaningless)
word "other" in some of the collection names.

That's going in the right direction, but doesn't not given enough guidance
as to why to avoid it. My suggested language:

The 'mis' (Uncoded) primary language subtag SHOULD NOT be used. According to
ISO 639, it is used to identify linguistic content whose language is known
but which does not *currently* have a corresponding subtag. It is thus
intrinsically unstable -- the addition of other codes in the future can
render its application invalid at any point without any warning -- and hence
incompatible with the stability goals of BCP 47. It is thus always
preferable to use other subtags: either "und" or -- with prior agreement --
private use subtags.

That&#39;s going in the right direction, but doesn&#39;t not given enough guidance as to why to avoid it. My suggested language:<br><br>The &#39;mis&#39; (Uncoded) primary language subtag SHOULD NOT be used. According to ISO 639, it is used to identify linguistic content whose language is known but which does not *currently* have a corresponding subtag. It is thus intrinsically unstable -- the addition of other codes in the future can render its application invalid at any point without any warning -- and hence incompatible with the stability goals of BCP 47. It is thus always preferable to use other subtags: either &quot;und&quot; or -- with prior agreement -- private use subtags.

I was surprised how many places this needed to be fixed.  Any time we try to 
say the same thing, or close, in multiple places, there's a chance they 
won't all agree with one another.  But I'm glad Addison went through and 
found all these.

Correct.  For my part I understood the existing text just fine, with its 
heavy dependence on the word "prefix."  I suppose we've learned lately that 
ordinary words like "miscellaneous" and "prefix" mean different things to 
different people, and some extra clarification is often needed.

That's right.  "sl-biske-rozaj" would be well-formed but not valid.

I think these changes should be sufficient.

I agree strongly with Peter. Let's suppose I have a SOAP service using the
BCP 47 protocol for communicating UI language preferences. My application
doesn't support (surprise) all possible BCP 47 language subtags, and
communicates an error back to the requester indicating when I don't accept a
particular language. Such action doesn't make me uncompliant.

The key for compliance is that if I say I'm interpreting a field according
to BCP 47,

   - I do not accept anything that isn't BCP 47 compliant,
   - Anything that I accept has to be interpreted according to BCP 47
   semantics.

There are other kinds of reasonable claims that I can make. I can say, for
example, that I interpret a field according to BCP 47, but with the addition
of 4 exceptions for backwards compatibility with previous versions of my
software.

I agree with Randy on this.  Section 2.2 of RFC 4646 says, "The Language 
Subtag Registry maintained by IANA is the source for valid subtags."  That 
is clear and unequivocal.

There will, of course, be systems and applications that are not fully 
conformant to BCP 47, with which conformant applications will have to 
interoperate, and that is fine and expected.  Those systems will impose 
their own restrictions.  Perhaps the worst cases are the simple-minded 
applications that assume a language tag must consist of a 2-letter language 
optionally followed by a hyphen and a 2-letter country, which isn't even 
conformant to RFC 1766.

But we are talking about making a change *to BCP 47 itself* that specifies 
the use of "mis" when the full Registry is not available, and that is not 
right.  Applications that have such a restriction, such as MARC apparently, 
do not attempt to conform to BCP 47, and so there is no point in putting 
text in BCP 47 that makes their limitations conformant.

I hope there is no expectation that this "usage note," whenever the RAs 
approve and publish it, needs to be copied to the Language Subtag Registry. 
I am already waiting for the online ISO 639-2 code lists to be updated (and 
only for that) before submitting a change request for the Registry for 
"mis".  Any further elaboration on this very, very edge-case subtag needs to 
reside in RFC 4646bis and not within the Registry.

I also agree with Randy that a private-use tag would be a much better choice 
than "mis" for tagging content in a language with no available subtag, 
either because the Registry doesn't have one or in the case of a non-BCP 47 
application that uses a subset of the full Registry.

If I want to tag text in Unilingua (http://en.wikibooks.org/wiki/Unilingua) 
you can bet I'll use "x-mirad" or something similar long before I use the 
completely uninformative "mis".

Dear Han,
I am certainly delighted by your request and the answers you get. I 
had to made a lot of fuss to obtain the temporarily interoperable, 
hence acceptable, RFC 4646 text we currently have, through 
clarifications mostly against me. However, I must be loyal and clear 
to every of yours: every decision you take on a given example and 
class of needs may restrict the whole RFC to that unique case in that 
class. If I am correct, the basic idea of the langtag designers was 
to preserve compatibility with RFC 3066. Preserving internal 
compatibility seems to be important the same. The responses you 
receive are enforcing the strictly hierarchical vision of languages 
that some favor, who had reasonably be made possible but not enforced.

The way I see it, the more you ("Unicode lobby") go the way you 
currently go, the more you associate RFC 4646 with linguists needs 
and content layers only. And therefore, the more you dissociate 
langtags from the container, network, and readership layers. No 
problem with me: I think this is correct, that cctags will fully 
support them, and in full elegant respect of RFC 4646 (private).

I thought only fair to underline it, in case some of you have "in 
between" applications I did not think of and cctags could not support 
in case of conflict between their equivalent langtag. The more I go, 
the more I see there is an interintelligibility aspect due to the way 
RFC 4646 uses ISO 639 (which documents language names code elements) 
as a source for langtags which document language code elements. This 
means that strict interoperability cannot apply between fuzzy 
notions, but one can organise mutual intelligibility enough for 
things to usually work: "I do not know exactly what you talk about, 
but I understand enough about it for _my_ kind of use".

But it also leads to confusions. For example, there is a tendency to 
confuse ISO 3166-1:2006's administrative languages with ISO 639 
language names. This in turn risk to unstabilize the whole digital 
system's virtuality. Everything is tied together within the global 
metastructure.

Good luck.

Responding to what I think Gerard's point is:

A language subtag MUST exist in the Language Subtag Registry, or be a 
private-use subtag or tag, in order to be used conformantly with RFC 4646. 
There is no provision in RFC 4646 for using two- and three-letter language 
subtags that are not in a past or present version of ISO 639-1 or -2 
(future: or -3) but are "accepted to be true" under some criterion.

This goes for other types of subtags as well.

The meaning of "mis" does not quite fall into the scope of the meaning of 
"to identify", the way I see it. The language is not identified, but some 
indirect information about language is given.

Perhaps "indicating" could be used instead of "identifying", but the 
following formulation might be better:

"It should only be used when more specific means of giving 
information about the language are unavailable."

I apologize for permitting a posting to get through to the ltru list

As a technical contributor, I rather like this proposal.

I am OK with this except for the recommendation to use "und".  If the 
"language is known," then it is not "undetermined."  I suggest:

"It is thus always preferable to use private-use subtags with prior 
agreement."

I might quibble with the wording "without any warning," since every time a 
new language subtag is added to the Registry, that language is potentially 
removed from the scope of "mis" (or it might be removed from the scope of 
some other language subtag, which is thus "narrowed," which is its own 
discussion).

I hate the way this minor and largely theoretical edge case is dragging down 
the project.  Are we almost ready to go with 4646bis except for "mis"?  Do 
any other issues needs to be resolved?  If so, can we spend some time on 
those issues as well?

"und" is always a possible alternate tag for any content. That is, even if I
know that content in my web page is English, I don't *have to* tag it with
English -- I can leave it untagged, which is the equivalent of "und". And
private use codes can present their own issues -- if you don't have any
prior agreement then "und" is arguably better.

I agree that it is usually better to tag content with as much information as
possible, but nothing in BCP 47 can require that. We could reorder the
sentence to express the priority, however.

It is thus always preferable to use other subtags: either a private use
subtag with prior agreement or failing that, "und".

The key difference is that for other cases, it doesn't make any difference
when a future code is added, but for this one it breaks stability. However,
I'm ok with dropping it.

Referring to http://www.inter-locale.com/ID/draft-ietf-ltru-4646bis-06.html

There are quite a number of fixes that still need to be made.

Example - cleaning up extlang to still be reserved.

extlang       = *3("-" 3ALPHA)         *; specific ISO 639-3 codes
=>
*extlang       = *3("-" 3ALPHA)         *; reserved for future use*



Records of type 'extlang' MUST have *exactly* one 'Prefix' field.
=>
[delete]

Values in the field 'Prefix' in records of type 'extlang' MUST NOT be
modified.
=>
[delete]


as new records.

   1. Codes that have a defined "macro-language" mapping at the time of
   their registration MUST be entered into the registry as records of type
   'extlang' with a 'Prefix' field containing the appropriate prefix tag.
   2. Codes that represent sign languages MUST be entered into the
   registry as record of type 'extlang' with a 'Prefix' field that matches the
   Basic Language Range "sgn" (see Section 3.3.1 "Basic Filtering" in
   [RFC4647] (Phillips, A., Ed. and M. Davis, Ed., "Matching of Language
   Tags," September
2006.)<http://www.inter-locale.com/ID/draft-ietf-ltru-4646bis-06.html#RFC4647>).

   3. All other codes MUST be entered into the registry as records of
   type 'language'.

=>
as new records of type 'language'.

record of type 'language' or 'extlang'
=>
record of type 'language'
[multiple instances]

script or extlang
=>
script

Extended language subtags (type 'extlang' in the registry; see Section
3.1 (Format
of the IANA Language Subtag
Registry)<http://www.inter-locale.com/ID/draft-ietf-ltru-4646bis-06.html#ianaformat>)
also appear between the primary language and subsequent (script, region, or
variant) subtags. Applications sometimes benefit from their judicious use in
forming language tags.
=>
[delete]

(unlikely: needs prefix="language-extlang1")
=>
(unlikely)


language-extlang combination "zh-hak" when this document was adopted
=>
language combination "zh" when this document was adopted

some examples and some items in the Changes section.

I don't agree that "und" is equivalent to "no tag," but I don't want to 
spend a lot of time arguing about it, since I believe "und" (like "mis") is 
an exceptional subtag that is likely to see very little use in the real 
world.

Whoa, time out.  When did we agree NOT to use the extlang mechanism for new 
639-3 languages that have a macrolanguage?  I know you wanted that, but 
where was the consensus that makes these wishes into "fixes that need to be 
made"?  This is why I wish we were using the issue tracker as we did for 
3066bis.

+1,
no need to discuss MARC and other good excuses to violate the SHOULD NOT.

LOL.  With all those virtual realities you never know.  Seriously,
"uncoded" is clearer than "miscellaneous", I like the new description.

Hello Chris,

There has been a proposal to add a link to http://www.langtag.net
to the LTRU WG charter page. I have asked the WG about input on
this, and have only seen positive feedback. I therefore assess
that there is WG consensus on adding a link to this page to our
charter page at http://www.ietf.org/html.charters/ltru-charter.html.

My understanding is that you are the right person to pass this
request to; if not, please tell me what to do.

Regards,    Martin.

According to ISO 639, it is used to identify linguistic content whose language is known but which does not *currently* have a corresponding subtag. It is thus intrinsically unstable -- the addition of other codes in the future can render its application invalid at any point without any warning -- and hence incompatible with the stability goals of BCP 47. It is thus always preferable to use other subtags: either "und" or -- with prior agreement -- private use subtags. 

I'm a bit confused here. We want to try to give absoulte stability
guarantees. But then we recommend 'und' (wrong to start with, because
we know what language it is, so calling it undetermined is lying)
or a private tag (inherently unstable and non-interoperable).
Why don't we just accept that 'mis' is unstable (no disagreement
here, of course), but instead of saying "invalid at any point without
any warning -- and hence incompatible with the stability goals of BCP 47",
warn the receiver that 'mis' may refer to a language that in the meantime
has been coded, and change our language, e.g. 'invalid' -> 'suboptimal'.

Regards,    Martin.

I think I have to side with Peter here. We inherently know that
no tag at all and things such as 'und' and 'mis' have a rather low
value. On top of that, we have the problem of wrong tagging in the
first place. I'd vastly prefer a repository that tagged documents
from 200 languages *correctly* and used 'mis' or so in the rare case
it got something in a language that the system wasn't envisioned to
handle, rather than a system that tried to tag everything with a
specific code but got half of that wrong.

The interoperability is much more on the level of correctly
using the available tags, rather than on the details of the use
of 'mis'.

Also, while it's easy to write 'don't use "mis" unless there is
no subtag for the language in question', it's very difficult to
test.

I agree.

According to ISO 639, it is used to identify linguistic content whose language is known but which does not *currently* have a corresponding subtag. It is thus intrinsically unstable -- the addition of other codes in the future can render its application invalid at any point without any warning -- and hence incompatible with the stability goals of BCP 47. It is thus always preferable to use other subtags: either "und" or -- with prior agreement -- private use subtags. 

I'm a bit confused here. We want to try to give absoulte stability
guarantees. But then we recommend 'und' (wrong to start with, because
we know what language it is, so calling it undetermined is lying)
or a private tag (inherently unstable and non-interoperable).
Why don't we just accept that 'mis' is unstable (no disagreement
here, of course), but instead of saying "invalid at any point without
any warning -- and hence incompatible with the stability goals of BCP 47",
warn the receiver that 'mis' may refer to a language that in the meantime
has been coded, and change our language, e.g. 'invalid' -> 'suboptimal'.

Such confusion is among the many adverse effects of rashly converting =20=

international standards, instead of building them brick by aware =20

I think it is highly questionable to say that MARC was "rashly converted" 
into ISO 639-2 or that Ethnologue was "rashly converted" into ISO 639-3. 
Both MARC and Ethnologue existed for decades before being used as the basis 
for ISO standards.

The real problem is that MARC specified what "mis" was supposed to mean, but 
ISO 639-2 merely gave it the name "miscellaneous languages" and left it for 
implementations to figure out.

That was the *very thing* that was changed by the recent change to =
'mis'.
(And there was a real change!) What used to be 'suboptimal' is now
'invalid' w.r.t. the use of 'mis'.

'mis' used to be interpretable in a stable way, but that is no longer
possible given the change. (Which is why I've been arguing against this
change all along.)

We have used 'und' as a general "unknown" tag, which is really required for
effective operation of language tags. We are equating "und" with _no_tag_;
the latter are preferred in environments where that can be done, but "und"
is required where it is not allowed. And in a situation of inheritance (like
xml:lang), there needs to be something that says "don't inherit from the
parent level, because I'm not sure that I and my children are the same".

The key question for any tag -- assuming a tag is valid -- is what a
recipient can correctly infer from the presence of that tag. With "und" I
can make no assumptions about what the content is. It may be in no language,
some language, more than one language, a language that has no code. I can
simply make no inferences. As to why the original tagger tagged it that way,
I can't know -- maybe he knew didn't know what it was, maybe he didn't try
to find out, maybe he tried and didn't have 100% confidence, maybe he knew
it was low elvish and there wasn't a code for it, whatever.

RFC 4930 has several normative references to RFC 3066.

RFC 4930 has been approved by the IESG in January 2007 and published
in May 2007.

RFC 3066 have been obsoleted by RFC 4646 in September 2006, several
months before.

I'll move this to a different thread, so we can focus on the "mis" language
under that title.

You had said: "Are we almost ready to go with 4646bis except for "mis"?  Do
any other issues needs to be resolved?  If so, can we spend some time on
those issues as well?"

There are at least three open issues listed in
http://www.inter-locale.com/ID/draft-ietf-ltru-4646bis-06.html.

Extlang is one of them. I'll step back a bit, since it appears that we don't
have consensus about making a change in extlang from RFC 4646.

So we need to revive the discussion from back in March.

It is difficult even for the IETF to keep track of its own standards

I believe so and I regret that "mis" takes so much energy. IMHO, it is
just a detail (I agree with Doug Ewell's "Type I vs. Type II errors"
message).

Most are either actually closed (I do not think that there are still
serious proposals to use UTF-8 in the registry: even if I regret it,
it seems settled) or only details (additional information related to
Suppress-Script).
 
> Extlang is one of them.

And probably the only serious one. But, on the other hand, I want to
emphasize that ISO 639-3 was issued in february, that some users want
the new language codes now and that any delay in the release of the
RFC undermines the whole language tag effort.

It's unfortunate that the ISO 639-3 code list still isn't truly ready for 
initial launch, and won't be until July, even though the standard has 
already been issued.  But that's the way it is, and our "stability" goals 
would not be served by incorporating the 639-3 code list as it is today and 
then being forced to keep any code elements they choose to remove between 
now and July (cf. the Occitan languages).

My wish is for us to have everything else ready *before* 639-3 announces its 
"final" code list, so that we can issue WGLC for 4646bis and 4645bis at that 
point without further delay.

That has *never* been the intent of ISO 639. It is an external interpretati=
on, admittedly possible because ISO 639 was not fully explicit up to now. B=
ut from the perspective of the JAC, the "new mis" is exactly the same "mis"=
 as the "old mis".

I agree.  For those who wish to follow the extlang discussion, the question 
is: for languages listed in ISO 639-3 that are not already present in the 
Registry, should we:

1.  add all of them as primary language subtags, or
2.  take the 5% that are encompassed by an ISO 639-3 macrolanguage, add them 
as extended language (extlang) subtags, and add the other 95% as primary 
language subtags?

The discussion in March started with this message from Mark:
http://www1.ietf.org/mail-archive/web/ltru/current/msg07288.html

Chase the "Follow-Ups" links to follow the thread.

My view is that we should keep the primary/extlang relationship that we have 
been planning since 2004 to reflect the ISO 639-3 macrolanguage 
relationship.  It allows identification of the individual languages while 
staying compatible with the way people have tagged them in the past, and in 
some cases with the way people will always perceive them (i.e. "Arabic" 
rather than 30 different flavors).  Expecting matching engines to have "a 
bit more smarts" so they can match "yue" with "zh" doesn't work for me when 
we can't even expect them to be smart enough to match "en-US" with 
"en-Latn-US".

But that's just my view, and the important thing is for the list to discuss 
the matter and reach a consensus so we can move forward.

At the moment you can reconstruct a 3066 registry by looking at
the redundant / grandfathered tags in the 4646 registry, and in
the source standards (i.e. the language and region subtags in the
4646 registry).

IOW just stay away from scripts, variants, and UN region numbers.

With the 4646bis registry it will be more convoluted, you'd also
have to stay away from 639-3 languages (+ extlangs, if any pop up).

Should 4646bis do something for protocols wishing to emulate the
old 3066 registry ?  We could flag the source of language tags in
the description field (just an idea).  Or add a how-to as appendix.

 From the perspective of a registry user seeing only the description
"uncoded" appears to be slightly broader than John's definition
"uncoded and not covered by any other collection".

E.g. "missingsch" is a mixture of nl, nds, and some other languages,
and I think it's "uncoded".  But it should be tagged as "gem", not
"mis".  Maybe the verbose explanation in 4646bis should copy the
verbose JAC-definition, and / or add an example.  Or add a comment
to the bulk registry update (individual registration doesn't work).

I agree.  I have had many difficulties with this.  I think it would be a
good idea if every time an RFC is made obsolete by the publishing of a new
RFC that the new RFC reference is added to the old RFC - preferably on the
first page under "Obsoletes:". Add a new line "Obsoleted by/date:" ? How
could this best be achieved across the IETF?

Like others, I have problems understanding that. Randy made
the procedural argument (both RFC 3066 and RFC 4646 are BCPs).

There is also an implementation argument:
There are no legal language tags in RFC 4646 that aren't legal
according to RFC 3066. I have absolutely no clue what could
break in an implementation when using a tag that became
legal in RFC 4646. The only thing that I can see break is
things such as "language not available", but then that kind
of error was always possible.

This is one interpretation, but there is also a different,
in my view more plausible, interpretation: RFC 4646 did a
bulk registration of language/region/script/whatever combinations.
Because it became obvious that there would be scaling problems
when registring all combinations, we took the path of changing
the registry structure. The old (RFC 3066) registry has been
obsoleted, there is only the RFC 4646 registry, which is
a direct continuation of the RFC 3066 registry. All the
tags you can generate from the new registry using the rules
in RFC 4646 are legal tags according to RFC 3066, and have
to be considered under RFC 3066 as if they were in fact
registered one-by-one.

Frank's interpretation would mean that only the variants
registered at the time RFC 3066 was replaced by RFC 4646
would be usable. That would lead to weird requests. I remember
that in the transition period from RFC 3066 to RFC 4646,
we had somebody requesting registration of el-Latn.
We rejected this because with RFC 4646, there would be no
such need anymore. With the interpretation above, that would
no longer be true.

No. There is no old registry. There is only one registry.
The current registry IS the RFC 3066 registry, just slightly
overhauled.

With this, of course the reasons for citing RFC 3066 when
RFC 4646 was out become even less understandable.

Surely that is quite easy to do as each subtag has a date?

Yes, it would be easy to reconstruct a "frozen" (2006) 3066 registry.

But I guess Scott's protocol tries to pretend that 3066 still exists,
i.e. new country codes like IM GG JE are okay, new 639-2 languages
like frr frs are okay, old redundant and grandfathered tags are okay,
while scripts, variants, 639-3 languages, and extlangs are NOT okay.

Personally I'd prefer "4646 registry minus scripts" (or similar) for
this purpose, but Scott said it's intentionally 3066.

Just to clarify, I think you or Randy mean "RFC 3066 used to be
a BCP before RFC 4646 obsoleted it".

Matching is tricky in the presence of script subtags (and other
less likely scenarios), it was one line in RFC 3066, now it's a
separate document.

For 4646bis no implementation will be able to match nl-BE with
what-was-it, vlm (?), by only looking at the registry, unless
we deprecate it manually in favour of nl-BE.

It makes perfect sense to exclude some constructs.  When I try
the language option of a "popular" search engine I won't find
de-1996 pages while looking for de, or en-GB-oed pages while
looking for en (I'm too lazy to check what it was, maybe both).

And I won't find frr pages while looking for fy-DE (or v.v.).
But that's no 639-3 or 4646 issue, it would be the same with
3066.  For 3066 stability was an implicit assumption, and 4646
made it explicit, trying to guarantee it for region tags.

RFC 3066, 4646, and 4646bis fail miserably when language tags
are narrowed, or when language-region combinations get their
own language tag.

Maybe we should keep RFC 4646 as is, and later replace it
wholesale by ISO 639-6.  The fy-DE and nl-BE examples (plus
the "extlang" discussion) are a warning.

This nl-BE confusion is in essence the same issue as the old
CS chaos, we're trying to mix standards designed to be used
for something else.  For ISO 639-3 it's logical to replace
nl-BE by something "better" as soon as somebody seriously
wants it, they don't know any "nl-BE", they only know "nl".

But we know that nl-BE exists, and we've no way to deprecate
it in favour of whatever comes, we could at best manually
deprecate the new subtag in favour of nl-BE.

For fy-NL, fy-DE, frr, and fy, let alone frs, I thought that
it's okay to ignore the implications, after all I tried to
find a single page tagged as fy-DE and found nothing.  But
for nl-BE (and zh-*) we might be in serious trouble.

I would have to disagree here.  I can see applications for using an "old"
registry in order to update to a "new" registry.

We can't do that; they are two different languages, though closely
related and intertwined in use  It would be like deprecating nds in
favor of de-northern.

And fy-DE could never have been more than a hack like zh-TW for zh-Hant:
is it North Frisian, or is it Saterfrisian aka East Frisian (not to be
confused with the variety of nds also called "East Frisian", still less
with the variety of Standard German (de) spoken in Ostfriesen)?

+2. I'll put that in the draft when I sit down with it again (later 
today??).

Incidentally, I'm preparing to submit draft-07.

No need to do that.  Just go to 
http://www.iana.org/assignments/language-tags .  IANA must be keeping the 
old registry around for some reason; this must be it.

Actually, we accepted it but it initially failed to make it into the 3066 
registry, since by that time 4646 was very close at hand indeed.  Months 
after 4646 weas released, the requestor argued forcefully to have "el-Latn" 
added to both registries.  IIRC there were veiled legal threats.

I admit to a lot of confusion regarding Scott's explanation.  When I was 
working on 4645, I heard frequently that RFC references must always refer to 
the latest revision, not to RFCs that have been superseded.  I'm sure nobody 
wants RFC authors to be able to pick and choose among obsolete RFCs to find 
the one with the most favorable, now-removed wording.

Unfortunately, ISO codes have somewhat of an impedance mismatch with the
needs of the IT community; in particular, stability. Thus BCP 47 has to
stabilize those codes; one of the main reasons for the existence of RFC
4646. What that means is that if ISO tries to narrow the meaning of *any*
code, whether it is a "clarification" or not, we have really only two
choices:

1. Keep the broader semantic, which encompasses the new ISO narrow one, or
2. Deprecate the code (in one way or another).

Unlike many other codes, "mis" is one that we can do without, so #2 was a
reasonable choice.

What I was trying to come up with language that we could agree on even
though we have very different views on the utility and meaning of 'mis'. It
sounds like we are ok on the suggested language on the other thread, so I'm
hoping that we can put "mis" to bed.

As far as the JAC is concerned, the intentional semantic of "mis" is what i=
t has always been. As for the extension, when 639-2 was the only alpha-3 co=
de, there was only one context to evaluate the extension that would be deri=
ved by that intention; 639-2 did not document the extension, though at leas=
t one application of 639-2 - MARC - did. With the introduction of 639-3 and=
 the pending introduction of 639-5 as additions to the alpha-3 space, it be=
comes clear that the extension must be determined within a context: the cas=
es where you'd want to use "mis" differ if you're using 639-3 rather than 6=
39-2. But for an application of a given part of 639, the change of referenc=
e name has had no effect on the extension for that context: the languages e=
ncompassed by "mis" in a 639-2 application, for instance, are the same as t=
hey were before.

When it comes to BCP 47, the change of reference name for "mis" is basicall=
y irrelevant because there is a much bigger issue: in RFC4646bis, BCP 47 wi=
ll change from being an application of 639-1 and -2 to being an application=
 of 639-1, -2 and -3. That change of context is what creates the issue wrt =
interoperability of "mis" in applications of BCP 47: Under RFC 4646, Burush=
aski content would be tagged "mis"; under RFC 4646bis, one would expect new=
 Burushaski content to be tagged "bsk". There's no basis for matching: that=
's an interop problem. And note that it has nothing to do with stability of=
 "mis" supposedly introduced with the name change: with or without that cha=
nge, Burushaski content would be tagged differently before and after.

And note that this issue exists whether one considers "old mis" to have the=
 semantic that Keld is stuck on, 'all languages', or the semantic that the =
JAC has always intended: either way, it is the addition of 639-3 to BCP 47 =
that creates an issue for uses of "mis" under BCP 47, not the name change.

And even without the addition of 639-3, "mis" would have interop issues: as=
suming the semantic the JAC has always assumed, the extension in the contex=
t of 639-2 could narrow - inherently by the nature of the semantic - any ti=
me a new entry was added; but assuming the 'all languages' semantic, one co=
uld end up with comparable content tagged in non-comparable ways, "mis" and=
 something else.

Therefore, I suggest that beating up ISO as not being in tune with the need=
s of the IT community is both fruitless and baseless, and is ignoring the f=
act that IETF has problems all of its own making. If IETF really wanted to =
avoid any stability or interop problems related to "mis", it should never h=
ave permitted its use in language tags, starting back in RFC 1766, because =
"mis" has always had stability / interop issues. But that horse is long out=
 of the barn: "mis" *can* be used in language tags under RFCs from 1766 to =
4646. The LTRU WG within IETF needs to decide what to do about that in RFC =
4646bis. That's a job for IETF; we don't need to continue bothering JAC mem=
bers with IETF issues.

That has *never* been the intent of ISO 639. It is an external interpretati=
on, admittedly possible because ISO 639 was not fully explicit up to now. B=
ut from the perspective of the JAC, the "new mis" is exactly the same "mis"=
 as the "old mis".

color:#1F497D'>As far as the JAC is concerned, the intentional semantic of =
&#8220;mis&#8221;
is what it has always been. As for the extension, when 639-2 was the only
alpha-3 code, there was only one context to evaluate the extension that wou=
ld
be derived by that intention; 639-2 did not document the extension, though =
at
least one application of 639-2 &#8211; MARC &#8211; did. With the introduct=
ion of
639-3 and the pending introduction of 639-5 as additions to the alpha-3 spa=
ce, it
becomes clear that the extension must be determined within a context: the c=
ases
where you&#8217;d want to use &#8220;mis&#8221; differ if you&#8217;re usin=
g
639-3 rather than 639-2. But for an application of a given part of 639, the
change of reference name has had no effect on the extension for that contex=
t:
the languages encompassed by &#8220;mis&#8221; in a 639-2 application, for
instance, are the same as they were before.<o:p></o:p></span></p>

color:#1F497D'>When it comes to BCP 47, the change of reference name for &#=
8220;mis&#8221;
is basically irrelevant because there is a much bigger issue: in RFC4646bis=
,
BCP 47 will change from being an application of 639-1 and -2 to being an
application of 639-1, -2 and -3. That change of context is what creates the
issue wrt interoperability of &#8220;mis&#8221; in applications of BCP 47:
Under RFC 4646, Burushaski content would be tagged &#8220;mis&#8221;; under=
 RFC
4646bis, one would expect new Burushaski content to be tagged &#8220;bsk&#8=
221;.
There&#8217;s no basis for matching: that&#8217;s an interop problem. And n=
ote
that it has nothing to do with stability of &#8220;mis&#8221; supposedly
introduced with the name change: with or without that change, Burushaski co=
ntent
would be tagged differently before and after. <o:p></o:p></span></p>

or the semantic that the JAC has always intended: either way, it is the
addition of 639-3 to BCP 47 that creates an issue for uses of &#8220;mis&#8=

<p class=3DMsoNormal style=3D'margin-bottom:12.0pt'>Unfortunately, ISO code=
s have
somewhat of an impedance mismatch with the needs of the IT community; in
particular, stability. Thus BCP 47 has to stabilize those codes; one of the
main reasons for the existence of RFC 4646. What that means is that if ISO
tries to narrow the meaning of *any* code, whether it is a
&quot;clarification&quot; or not, we have really only two choices: <br>
<br>
1. Keep the broader semantic, which encompasses the new ISO narrow one, or<=
br>
2. Deprecate the code (in one way or another).<br>
<br>
Unlike many other codes, &quot;mis&quot; is one that we can do without, so =
#2
was a reasonable choice. <br>
<br>
What I was trying to come up with language that we could agree on even thou=
gh
we have very different views on the utility and meaning of 'mis'. It sounds
like we are ok on the suggested language on the other thread, so I'm hoping
that we can put &quot;mis&quot; to bed.<br>

Unfortunately, ISO codes have somewhat of an impedance mismatch with the
needs of the IT community; in particular, stability. Thus BCP 47 has to
stabilize those codes; one of the main reasons for the existence of RFC
4646. What that means is that if ISO tries to narrow the meaning of *any*
code, whether it is a "clarification" or not, we have really only two
choices:

1. Keep the broader semantic, which encompasses the new ISO narrow one, or
2. Deprecate the code (in one way or another).

Unlike many other codes, "mis" is one that we can do without, so #2 was a
reasonable choice.

What I was trying to come up with language that we could agree on even
though we have very different views on the utility and meaning of 'mis'. It
sounds like we are ok on the suggested language on the other thread, so I'm
hoping that we can put "mis" to bed.

After a private exchange with Randy Presuhn of the LTRU working group I
realized it might be helpful if I provide more info to explain why 4930
references 3066 instead of 4646.  First, let me confirm that this wasn't
an oversight.  It was a conscious decision made with the concurrence of
the IESG as we looked at the normative references and the standards
track status of those references.  Rationale:

1. 4930 is the draft standard version of 3730, updated to document
implementation experience with 3730.  3730 references 3066.  The first
drafts of what would become 4930 referenced 3066 before 4646 was
approved and published.  Implementers of 3730 and 4930 wrote code per
3066.

2. 3730 and 4930 include a language tag reference because language tags
are used within XML Schema elements.  The October 2004 edition of the
normative XML Schema datatypes reference cites 3066:

http://www.w3.org/TR/xmlschema-2/#language

Consistency was thus thought to be a good thing.  If this were new work
I'd agree that 4646 would be the more appropriate reference, but that
would also depend on the XML specifications picking up 4646 as well.

Sometimes I think they're making up languages for non-technical
reasons.

All you can know is that it's not West Frisian (fy since 2006).

For the frr suppress-Latn registration request I tried to find
some background info, apparently frr is subdivided into three
or more variants.

Yeah, I made sure that Wikipedia had this right when I was at
it about a year ago.

I'd guess that that's no language, when nds-folks speak "de"
they end up with a rather pure "de".

Sometimes I think so too, but I don't think this is one of them.
Low Saxon (or whatever you want to call it) is pretty clearly established,
though whether the non-Dutch dialects in the Netherlands are really all
that separate from it is a question.

Pretty much mainlander, islander (except Sylt which is no longer
Frisian-speaking in practice), and Heligolander.  Of course, finer
distinctions can be and are made.

Well, that's what de is:  High German syntax in Low German phonology
(cf. "lingua toscana in bocca romana").

If you feel strongly about this, you could ask for it to be registered
as an (exceptional) RFC 4646 language subtag.  "Root" is too short,
but "somelang" would work.

It's an idea, maybe "dummy" is a good name.  It should be
combined with scripts, otherwise it's probably pointless.

But it's still very near to "und", why would anybody wish
to make the very subtle point und-Latn vs. dummy-Latn ?

The main concern I had is deprecating the unstable "mis". I used "root" to
contrast with how it could have been done in a stable fashion. The code
"und" is a superset of "root" -- the basic difference being that "und" can
also include non-linguistic content. So I don't think it is a priority right
now to have a separate code, compared to finishing the other items in
4646bis.

The main concern I had is deprecating the unstable &quot;mis&quot;. I used &quot;root&quot; to contrast with how it could have been done in a stable fashion. The code &quot;und&quot; is a superset of &quot;root&quot; -- the basic difference being that &quot;und&quot; can also include non-linguistic content. So I don&#39;t think it is a priority right now to have a separate code, compared to finishing the other items in 4646bis.

mes *incorrectly* tagged when an ID for the given language is added. But le=
t's consider whether it is *usefully* tagged: changing things so that it co=
uld continue to be *correctly* tagged wouldn't make it more *usefully* tagg=
ed, and arguably makes it less so.

To suggest that users needn't worry about their content tagged 'root' after=
 a new language is coded is IMO bad advice. They certainly *should* worry i=
f they want their data to be useful: they'll want to re-tag the relevant co=
ntent with the newly-coded ID, else they end up with data that won't compar=
e. At least if they know that the addition will narrow the extension and po=
tentially invalidate tagging on some of their content, they're more likely =
to pay attention; what you suggest can give the impression that they don't =
have any particular worry, which is not the case.

A tag with the 'root' semantic can always mean anything - which means it's =
nearly void of meaning and is about as useful as not having tagged it at al=
l in the first place. (The 'root' semantic would be equivalent to 'not zxx'=
.) That's not *usefully* tagged, but it's vacuously always going to be vali=
dly tagged - big deal. At least with the 'uncoded' semantic they can use ch=
ange history for the code table and the record date to derive a short list =
of what languages "mis" content might be in - a pain, but that's actually m=
ore useful that 'some language'.

I really didn't want to start a flame about this; I'm sorry if what I said =

This whole issue is not really connected with the change from part 2 to par=

s" in BCP 47 whether "brk" were added because of 639-3 OR just because it w=

And the sad thing is that this instability in ISO codes is completely avoid=

 *   Have a code I'll call here "root" (to avoid any misunderstanding about=
 the meaning of "mis".)
 *   Have it be valid to tag any language content with "root".
 *   State that one SHOULD tag as narrowly as possible, thus avoid "root" i=
f there is a more specific language code.
This completely takes the place of the need you see for "mis", *without bei=
ng unstable*. If I have some Burushaski content, where a code doesn't exist=
, I tag it with "root". That is valid now, and remains valid forever, even =
once "brk" is added -- whether "brk" were added because of 639-3 or just be=

When it comes to BCP 47, the change of reference name for "mis" is basicall=

ll change from being an application of 639-1 and -2 to being an application=
 of 639-1, -2 and -3. That change of context is what creates the issue wrt =
interoperability of "mis" in applications of BCP 47: Under RFC 4646, Burush=
aski content would be tagged "mis"; under RFC 4646bis, one would expect new=
 Burushaski content to be tagged "bsk". There's no basis for matching: that=
's an interop problem. And note that it has nothing to do with stability of=
 "mis" supposedly introduced with the name change: with or without that cha=
nge, Burushaski content would be tagged differently before and after.



And note that this issue exists whether one considers "old mis" to have the=
 semantic that Keld is stuck on, 'all languages', or the semantic that the =
JAC has always intended: either way, it is the addition of 639-3 to BCP 47 =
that creates an issue for uses of "mis" under BCP 47, not the name change.



And even without the addition of 639-3, "mis" would have interop issues: as=
suming the semantic the JAC has always assumed, the extension in the contex=
t of 639-2 could narrow - inherently by the nature of the semantic - any ti=
me a new entry was added; but assuming the 'all languages' semantic, one co=
uld end up with comparable content tagged in non-comparable ways, "mis" and=
 something else.



Therefore, I suggest that beating up ISO as not being in tune with the need=
s of the IT community is both fruitless and baseless, and is ignoring the f=
act that IETF has problems all of its own making. If IETF really wanted to =
avoid any stability or interop problems related to "mis", it should never h=
ave permitted its use in language tags, starting back in RFC 1766, because =
"mis" has always had stability / interop issues. But that horse is long out=
 of the barn: "mis" *can* be used in language tags under RFCs from 1766 to =
4646. The LTRU WG within IETF needs to decide what to do about that in RFC =
4646bis. That's a job for IETF; we don't need to continue bothering JAC mem=

Unfortunately, ISO codes have somewhat of an impedance mismatch with the ne=
eds of the IT community; in particular, stability. Thus BCP 47 has to stabi=
lize those codes; one of the main reasons for the existence of RFC 4646. Wh=
at that means is that if ISO tries to narrow the meaning of *any* code, whe=
ther it is a "clarification" or not, we have really only two choices:

1. Keep the broader semantic, which encompasses the new ISO narrow one, or
2. Deprecate the code (in one way or another).

Unlike many other codes, "mis" is one that we can do without, so #2 was a r=
easonable choice.

What I was trying to come up with language that we could agree on even thou=
gh we have very different views on the utility and meaning of 'mis'. It sou=
nds like we are ok on the suggested language on the other thread, so I'm ho=
ping that we can put "mis" to bed.

That has *never* been the intent of ISO 639. It is an external interpretati=
on, admittedly possible because ISO 639 was not fully explicit up to now. B=
ut from the perspective of the JAC, the "new mis" is exactly the same "mis"=
 as the "old mis".

ISO codes have somewhat of an impedance mismatch with the needs of the IT
community; in particular, stability. Thus BCP 47 has to stabilize those cod=

one of the main reasons for the existence of RFC 4646. What that means is t=

if ISO tries to narrow the meaning of *any* code, whether it is a
&quot;clarification&quot; or not, we have really only two choices: <br>
<br>
1. Keep the broader semantic, which encompasses the new ISO narrow one, or<=

2. Deprecate the code (in one way or another).<br>

What I was trying to come up with language that we could agree on even thou=

we have very different views on the utility and meaning of 'mis'. It sounds
like we are ok on the suggested language on the other thread, so I'm hoping
that we can put &quot;mis&quot; to bed.<br>

Not so much.  We had an excellent idea of what 639-3 would both look and
actually be like when 4646 was finalized.  We couldn't include 639-3 or
extlangs because 639-3 itself was not yet final.

> nor did we have agreement on what we should actually do.

We had at least the consensus of silence; at least, I don't remember any
complaints at the time.  Remember that the development of 4646 started at
least a year before LTRU was formally created.

> We *already* had macrolanguages with ISO 639-2 in RFC 4646 and we *did
> not* use extlang for them: examples are "sr", "hr", "nb", etc.

(Rather, these are examples of languages *encompassed* by macrolanguages,
henceforth "encompassed languages".  I realize that's just a slip.)

> We are not going to (and cannot) be forcing users to encode nb as no-nb,
> nor sr as sh-sr.

Nobody has ever proposed that.  Language subtags coming from 639-1
or 639-2 will not change, even if 639-3 says they encode encompassed
languages.

> When we ("Google") tried implementing matching with "zh-yue" and others,
> we found it made things *more* difficult, not less.

Respectfully I suggest that because you ("Google") assign tags to incoming
rather than outgoing content, your use of BCP 47 is essentially private
rather than in interchange.  That makes it potentially important, but
definitely not prototypical.

> Matching "zh" and "yue" is not something you want to do
> automatically. Moreover, because of #2 we had to have a mechanism for

Very plausible in your circumstances.  But note that Yue (Cantonese)
content is *already* properly tagged "zh-yue" on precisely the theory
that's being applied to 639-3 encompassed languages.

I realize that this cause is probably not important to you, because
you can (comparatively) easily change all "zh-yue" tags to "yue", but
this is not the case for other users of BCP 47 on and off the Internet,
who will never even hear about the change.

> Thus to make a proposed change from 4646 to use the extlang mechanism

On the contrary, the burden of persuasion is with you.  Tags like
zh-yue are already present in 4646, and it's up to you to provide a
convincing argument to deprecate them.  Furthermore, LTRU and its ad hoc
predecessor has been assuming the extlang structure since at least 2004.
Derailing that is what will take a "very compelling case".

> A. [Don't use extlangs.]

I continue in opposition to this.

> B. (optional) Add a field Macrolanguage: to the language subtag
> registry.

I am not opposed to this, precisely because encompassed languages and
the corresponding macrolanguage cannot be identified syntactically.

Just to clarify something, in case anyone isn't familiar or doesn't remembe=
r: note that the tag "zh-yue" was not proposed because a scheme based on 63=
9-3 macrolanguages was anticipated. Rather, this and other tags were regist=
ered several years before the notion of macrolanguages was first considered=
 for 639-3. In fact, the other way around: it was this and other similar re=
gistered language tags that led to the idea of macrolanguages for 639-3.

Hello Debbie,

I'm not sure I can parse the above sentence correctly. Are you saying
that somebody could, now, make an application for registration on
http://www.iana.org/assignments/language-tags according to RFC 3066?
At http://www.iana.org/numbers.html#L, it explicitly says
"No further registrations in this registry.".
Or are you talking about something else?

Regards,   Martin.

Well, yes, very good point. In that sense, using RFC 3066 instead
of RFC 4646 is actually a bad idea, it means that you are going
to Draft Standard with a reference to something that was a BCP
rather than with a reference to an actual BCP.

Yes, that's a valid point (but probably the only one). That means
that in RFC 4930, it might have said something like "this protocol
uses Basic Filtering as defined in RFC 4647 for matching language
tags". But my guess is that not even this is needed.

The protocol just sends languages that the server has available,
and the client is free to use that to pick whichever it thinks might
work (including, e.g., showing the list to a user).

Also, the protocol has some elements where the language can be
indicated. Here is an example, taken directly from the spec:

   - A <msg> element containing a human-readable description of the
         response code.  The language of the response is identified via
         an OPTIONAL "lang" attribute.  If not specified, the default

Hello Debbie,

I'm not sure I can parse the above sentence correctly. Are you saying
that somebody could, now, make an application for registration on
http://www.iana.org/assignments/language-tags according to RFC 3066?
At http://www.iana.org/numbers.html#L, it explicitly says
"No further registrations in this registry.".
Or are you talking about something else?

Yes, that's a valid point (but probably the only one). That means

There is nothing in terms of matching here, just simple identfication.

The second is the last sentence, which seems to prescribe a
value for an attribute that is optional. It would be better if
it were reworded as "If not specified, the implied attribute

to say that the content of the <msg> element has to be English
in the absence of a lang attribute. Using 'implied' is much
clearer, because it's the terminology that XML is using.
The third problem is the use of "en" rather than "i-default".
The later is specifically defined for this fallback purpose.

It makes perfect sense for some servers to exclude some languages,

Okay, but on hindsight, and looking at things in detail, I still
think that this decision was wrong, and that it shouldn't be
repeated.

If you could explain how writing code per 3066 and writing code per
4646 would lead to any difference in the actual code or the observable
protocol behavior, that would help us to accept this point.

If you look at this, you will easily see that:
- The lexical space defined is in no conflict at all with the syntax
  of RFC 4646.
- RFC 4930, in its normative prose, only says that language tags must
  be "structured as documented in [RFC3066]". While RFC 3066 didn't
  use these terms, it essentially means that they must be "RFC 3066
  well-formed", not "RFC 3066 valid".
  The only point you might be able to claim here is that changing this
  to RFC 4646 might create a requirement for implementations to check
  for RFC 4646 well-formedness, which is admittedly a bit tighter than
  RFC 3066. But the MUST is on the sender, where we can assume that
  only valid stuff is used anyway, and you have no error message for
  non-well-strucured-language-code, which makes sense because
  the usual behavior, "language not available", is just good enough.

>Consistency was thus thought to be a good thing.

The problem is that with this, you may have excluded a lot of languages
from potentially being used in your protocol, and you have created the
impression that updating from RFC 3066 to RFC 4646 is a major undertaking,
which in most cases, it is not.

>If this were new work

XML already has (see http://www.w3.org/TR/REC-xml/#sec-lang-tag).
For a previous version
(http://www.w3.org/TR/2004/REC-xml-20040204/#sec-lang-tag),
it already says "RFC 3066 or its successor".

As for XML Schema, I'm very sure they'll make the move. A previous
version was on RFC 1766.
http://www.w3.org/TR/2001/REC-xmlschema-2-20010502/#language
If in doubt, it would have been easy for the WG or the IESG to
check with W3C.

Regards,    Martin.

John did a fine job articulating most of my position.  Anything not

In particular, we knew there would be macrolanguages and encompassed 
languages.  This was spelled out by Peter Constable on 2004-01-30 in a post 
which laid out the extlang concept for the first time:

http://www.alvestrand.no/pipermail/ietf-languages/2004-January/001658.html

I thought it was stronger than that, that just about everyone's expectation 
and understanding was that extlangs were intended for encompassed languages, 
and that encompassed languages would be represented by extlangs.  Tags like 
"zh-cmn" were registered at ietf-languages specifically so they would 
conform to this well-understood model.

>> Matching "zh" and "yue" is not something you want to do automatically.

That's only half true.  All Cantonese is Chinese, and since it's only been 
possible up to this point to tag Cantonese as "zh-something", it's 
reasonable to assume that much of it will continue to be tagged as 
"zh-something" in the future.

>> B. (optional) Add a field Macrolanguage: to the language subtag registry.

So, for example:

Type: language
Subtag: qvc
Description: Cajamarca Quechua
Description: Quechua, Cajamarca
Added: 20xx-xx-xx
Macrolanguage: que

Would content in Cajamarca Quechua be required to be tagged as "qvc", or 
would "qu" also be acceptable?  (We all know "qu" would be widely used.) 
Would matching engines be permitted to perform one- or two-way matching 
between "qvc" and "qu"?  What about users who expect we will go through with 
the "qu-qvc" model, and the Web pages that have already started listing such 
tags?  (See www.udhrinunicode.org, for instance.)  Would all this require an 
update to 4647?

Hi Martin

No I did not mean to register new subtags according to 3066.  What I mean is
that I can see an application for doing (say) a transaction within a
database that will bring out all records that match the Registry as it stood
in the 3066 era.  Perhaps in a housekeeping/update routine. Is there a way
to pull that historical registry once ISO 639-3 is added?

Best regards

Debbie

Subject: RE: (iso639.2708) RE: ISO 639-2 decision: "mis"



As far as the JAC is concerned, the intentional semantic of "mis" is what it
has always been. As for the extension, when 639-2 was the only alpha-3 code,
there was only one context to evaluate the extension that would be derived
by that intention; 639-2 did not document the extension, though at least one
application of 639-2 - MARC - did. With the introduction of 639-3 and the
pending introduction of 639-5 as additions to the alpha-3 space, it becomes
clear that the extension must be determined within a context: the cases
where you'd want to use "mis" differ if you're using 639-3 rather than
639-2. But for an application of a given part of 639, the change of
reference name has had no effect on the extension for that context: the
languages encompassed by "mis" in a 639-2 application, for instance, are the
same as they were before.

 

When it comes to BCP 47, the change of reference name for "mis" is basically
irrelevant because there is a much bigger issue: in RFC4646bis, BCP 47 will
change from being an application of 639-1 and -2 to being an application of
639-1, -2 and -3. That change of context is what creates the issue wrt
interoperability of "mis" in applications of BCP 47: Under RFC 4646,
Burushaski content would be tagged "mis"; under RFC 4646bis, one would
expect new Burushaski content to be tagged "bsk". There's no basis for
matching: that's an interop problem. And note that it has nothing to do with
stability of "mis" supposedly introduced with the name change: with or
without that change, Burushaski content would be tagged differently before
and after. 

 

And note that this issue exists whether one considers "old mis" to have the
semantic that Keld is stuck on, 'all languages', or the semantic that the
JAC has always intended: either way, it is the addition of 639-3 to BCP 47
that creates an issue for uses of "mis" under BCP 47, not the name change. 

 

And even without the addition of 639-3, "mis" would have interop issues:
assuming the semantic the JAC has always assumed, the extension in the
context of 639-2 could narrow - inherently by the nature of the semantic -
any time a new entry was added; but assuming the 'all languages' semantic,
one could end up with comparable content tagged in non-comparable ways,
"mis" and something else.

 

Therefore, I suggest that beating up ISO as not being in tune with the needs
of the IT community is both fruitless and baseless, and is ignoring the fact
that IETF has problems all of its own making. If IETF really wanted to avoid
any stability or interop problems related to "mis", it should never have
permitted its use in language tags, starting back in RFC 1766, because "mis"
has always had stability / interop issues. But that horse is long out of the
barn: "mis" *can* be used in language tags under RFCs from 1766 to 4646. The
LTRU WG within IETF needs to decide what to do about that in RFC 4646bis.
That's a job for IETF; we don't need to continue bothering JAC members with
IETF issues.

Unfortunately, ISO codes have somewhat of an impedance mismatch with the
needs of the IT community; in particular, stability. Thus BCP 47 has to
stabilize those codes; one of the main reasons for the existence of RFC
4646. What that means is that if ISO tries to narrow the meaning of *any*
code, whether it is a "clarification" or not, we have really only two
choices: 

1. Keep the broader semantic, which encompasses the new ISO narrow one, or
2. Deprecate the code (in one way or another).

Unlike many other codes, "mis" is one that we can do without, so #2 was a
reasonable choice. 

What I was trying to come up with language that we could agree on even
though we have very different views on the utility and meaning of 'mis'. It
sounds like we are ok on the suggested language on the other thread, so I'm
hoping that we can put "mis" to bed.

That has *never* been the intent of ISO 639. It is an external
interpretation, admittedly possible because ISO 639 was not fully explicit
up to now. But from the perspective of the JAC, the "new mis" is exactly the
same "mis" as the "old mis".

This is exactly the sort of application I had in mind when I proposed (many
moons ago) that the syntax be changed to include "[RFC3066]" within the tag
(something similar was originally proposed within Dublin Core). How much
easier it would be for those within archive industries.  

Best regards

Debbie

Or, indeed, as "zh" simpliciter, which is probably how most of it is
tagged based on a simplistic subset of RFC 1766.

In theory it's always possible to recover a historical version of the RFC 
*4646* Registry by looking at the "Added" dates.  This actually doesn't work 
perfectly because modifications don't affect the Added date.

Extracting the RFC *3066* registry is a different problem, because the 
nature of the records to be extracted isn't the same.  Not only were there 
no script subtags, but language and region subtags weren't defined within 
the 3066 registry, but rather within ISO 639 and 3166 (so users had to dig 
through the standards to find valid code elements, and the status of 
"withdrawn" code elements was unclear).  The 3066 registry contained only 
things that we would today consider for "variant" status.  Going from 4646 
to 3066 has more to do with understanding the two specifications and 
registries, and the differences between them, than with the actual data.

Proposal: RFC4645bis should preserve existing dates in the 4646-based 
registry. Then pulling the "historical" (4646) registry would be 
possible. Probably this is what you're doing already, Doug, but the text 
doesn't say so.

I agree with Doug and John's comments over the past couple of days.

I also agree with Mark that there are certain problems with extended 
language subtagging. Notably, there are matching implications. I was 
able to address that in my own implementations by:

- using extended rather than basic filtering
- treating the primary plus extlang sequence as atomic in lookup

That is, the fallback from zh-yue-Hant goes:

  zh-yue-Hant
  zh-yue
  (default)

I guess I agree about adding "Macrolanguage" to the registry, except 
that extlang, if preserved, already indicates this with "Prefix".

I can comfirm that I am Danish, and that I listen in on this.
Bu, indeed, my activity is low here.

Can someone explain this statement in 3.3.2 (Extended Filtering) of RFC 464=
7:

"This is the reason why a wildcard in the extended language range is signif=
icant in the first position but is ignored in all other positions."

I don't see how "*" is said to be ignored in non-initial position of a rang=
e. Step 1 says, "Two subtags match if either they are the same when compare=
d case-insensitively or the language range's subtag is the wildcard '*'." S=
teps 2 and 3 refer to subtags "match[ing]", where "match" is defined in ste=
p 1, and these steps apply only to non-initial positions. Step 3.A also mak=
es explicit reference to "*" in the range subtag -- again, this being non-i=
nitial subtags.

I can't figure that sentence out.


Thanks
Peter

Ignored is probably the wrong word. The sentence really means: "[t]his 
is the reason why a wildcard in the extended language range is only a 
significant difference in the first position but whose inclusion (or 
omission) has no effect elsewhere in the range."

I think perhaps both of our "we"s are overstated. Since we disagree on this
point, neither my "we" nor your "we" is inclusive.

For example, you can't mean that every member of the working group had
looked it over thoroughly, and explored all the implementation
ramifications. I'd like to see a show of hands for those who did -- maybe
everyone except for me had, but I'd be rather surprised at that.

I don't think everyone had reviewed it in detail, but perhaps the show of
hands would prove me the only one.

My point was that anyone who wants to deal with macro languages, has to
already deal with sr, hr, etc. as primary subtags, not as secondary. Thus
whatever mechanisms people have to work with sh, etc. can be extended to
other cases without the extlang mechanism.

First of all, that isn't true (but thanks for the "respectfully"!) We
actually use language tags in a huge number of products, many of which have
APIs. We are not fully BCP 47 compliant, but are working towards that.

But the main point is, I want those people who have tried to implement --
professionally, not just in toy programs -- extlang to speak up about their
experiences. So if you want to speak to your experience implementing this
professionally, I'm all ears.

Addison mentions that fallback matching is not a problem. Mechanically it is
a no-brainer. But the *results* of that fallback are what we are having
problems with. And *that's* why I raise this issue, and call it "baking in
an assumption". Let me try to set this out, yet again. I'll call the
"languages encompassed by a macrolanguage" by the term "microlanguage", just
as a term.

I see two options. I may have captured the extlang reasoning incorrectly, so
please bear with me. And if there are other reasons for having extlang,
that'd be good to hear.

Premises

   1. The reason for making microlanguages be extlang instead of primary
   sublanguages is so that truncation-style matching will have better results.
   2. Fallback works when there is mutual comprehensibility (not
   necessarily 100%, but to a high degree); if you fallback to something that
   is not comprehensible, then fallback has failed.

Option A.

   1. Thus for extlang to work for microlanguages, the speakers of any
   microlanguages sharing a macrolanguage need to be able to understand the
   speakers of any other microlanguages sharing that macrolanguage.
   2. Peter and the ISO JAC can verify that A1 is true; that every
   speaker of Hakka can understand Jinyu; every speaker of Shihhi Arabic
   can understand Cypriot Arabic; and so on).
   3. Everything is hunky-dory.

Option B.

   1. The macrolanguage alone is always assumed to be the "standard", and
   that can be identified. That is, "zh" is always assumed to be Mandarin,
   "ar" is always assumed to be "Standard Arabic", etc. (That is, I think, the
   correct approach, but is *not* currently in the spec.)
   2. Thus for extlang to work for microlanguages, the speakers of any
   microlanguages sharing a macrolanguage need to be able to understand the
   speakers of the standard used for that macro language.
   3. Peter and the ISO JAC can verify that B21 is true; that every
   speaker of Hakka can understand Mandarin; every speaker of Shihhi
   Arabic can understand Cypriot Arabic, and so on).
   4. Everything is hunky-dory.

If both A and B are not plausible, and we can't find something other
compelling reason to have extlangs, it is *far* better to add the
Macrolanguage field to the registry, and let people implement their own
matching making use of that AND other factors.

After all, it is trivial to make a 4647bis that adds an optional step for
microlanguages, which is that when you get to a microlanguage, the next step
is to look at its macrolanguage before falling back to the default. That has
the same result (and same problems) as extlang, but is something that is not
baked into the standard -- is something that people can implement if they
want without impacting matching for everyone else.

These are irregular tags anyway, and can stay irregular tags afterwards. We
and everyone else already have to deal with equivalences with grandfathered
and irregular tags anyway; these are not a real problem.

I disagree strongly. If you can't make a compelling case that extlang will
make BCP 47 better instead of worse, and won't even look at the reasons not
to do it, nor even bother to set out a case for it, then why should we add
it?

Martin,

The bottom line in my opinion is that 3730 implementers weren't writing
code with 4646 as a reference and it didn't seem wise to introduce a
reference change *that allows the possibility of required code changes*
and is *inconsistent with other normative references* when going from
proposed to draft.  More below.

You touched on this yourself below.  Additional language tags are
possible.  While I agree that this should be transparent to EPP, I
didn't see any compelling reason to require implementations and the user
interface code above those implementations to deal with the possibility.
I also had no assurances that existing XML Schema processors would
remain unaffected given that the 2004 XML Schema specs still cite 3066.

So you see no problem with including a normative reference to 4646 even
though the normative XML Schema spec cites 3066?  I do, and I believe
the IESG would have as well.

I've created no such impression.  I left the reference exactly as it was
when 3730 was approved by the IESG.  There haven't been any EPP
implementers screaming for support for 4646 language tags, so with 4930
NOT being new work there was no compelling reason to change the
reference.

They might, but they haven't, and that creates a consistency problem.

...

As cranky list admin and co-chair -

With no comment on this specific message, I would ask that all
posters to this list carefully consider:
   (1) does my post help advance the completion of the ltru WG's work?
       (e.g., address a specific problem by proposing specific text
       for the documents we are working on)
   (2) if cross-posting, does the message also advance the progress
       of the other mailing lists' work?
   (3) if you still think you need to cross-post, consider whether the
       issue might need to be split up into distinct questions to be
       addressed on the appropriate list.

I'm actually starting to suspect the recipient threshold isn't low enough;
the overwhelming majority of the ltru/ietf-languages crossposts have been,
in my opinion, questionable if not simply inappropriate.

Randy

Let me check that I understand. The only way, currently, to see if a
language is a macrolanguage is to check if there exists at least one
extlang which references it in its Prefix field? Correct?

So, in SQL:

SELECT Languages.code AS macrolanguage, count(Extlangs.code) AS Extlangs 
      FROM Languages,Extlangs WHERE Extlangs.prefix = Languages.code 
      GROUP BY Languages.code ORDER BY Languages.code; 

Which yields 54 macrolanguages in 4645bis, zap (Zapotec) being the one
with the most extlangs, 58 (if we do not count the sign languages).

Am I correct? (Sorry for using the IETF for my e-learning but I prefer
to check before commenting.)

Essentially correct.

Note that the proposals I've seen weren't to add pointers in the 
macrolanguage's record to the extlangs, but rather an additional pointer 
in the extlang to the macrolanguage. That strikes me as pointless except 
for the grandfathered ISO 639-2 codes enclosed by macrolanguages that 
can't be extlang.

I take it you're suggesting (or interpreted the proposal) to mean that 
the macrolanguage would contain a pointer or pointers to its 
sublanguages. Hence something like:

%%
Type: language
Subtag: zh
Description: Chinese
...
Encloses: yue,cmn,.....
%%

Is that what you had in mind? Note that this type of field could apply 
even when various grandfathering rules (hello "sh", etc.) don't permit 
the use of extlangs.

I don't think that is being proposed at all.  Stephane just asked:

If whether a language is a macrolanguage is an important property,
then it is worth discussing whether it should be flagged in its
record, rather than requiring it to be computed by examining all
other records.

If there is a real expectation that this will happen, this
will be critical to the extlang discussion, due to the
implications for stability in encoding.

Yes, although I think we dealt with that: the encoding is stable and the 
newly enclosed language remains a primary language. Such an eventuality 
would be supremely icky.

There was also a proposal (I think I made it) to limit extlangs to "at 
4646bis birth only"---that is, only currently enclosed languages that 
are otherwise unencoded would be extlangs. This gets us the (for 
example) the enclosed Chinese dialects (etc.), but not any future 
extlangs. Future registrations would be primary language subtags only.

I don't see why.  Stability says that once a language subtag,
always a language subtag: nothing is demoted to extlang subtag
status.  So languages that are encompassed in 639-2 today
have the same status (language subtag) as languages encompassed
in 639-3 later on.

The more serious case is when an encompassed language is no
longer encompassed or its macrolanguage is changed.
We'd be free to change the proposed Macrolanguage: field,
but the Prefix: field and Type: fields would have to remain.

Alternatively, to look back at 639-3.  There are currently two
such properties in 639-6 that are not represented in the LSR: scope
(individual, macrolanguage, collective) and type (living, [recently]
extinct, ancient, historic [stage of a living language], constructed).

I am neither for nor against including these properties in the LSR.
They aren't necessary for validation, but they are probably useful in
some circumstances.

I think it's important to keep in mind the "division of labor" between
the ltru WG and the function of the ietf-languages@iana.org list.
Here in the WG, we need to ensure that the registry and registration
process ensure that the right bits get recorded in the right spots,
and that the resulting language tag structure works.  We only have to
agree that there are cases of "enclosing languages" that make it
worthwhile to represent this property in the regsitry, and to account
for in in our matching algorithms.

Deciding which specific languages are to be given such treatment
does not belong here.  We only need to concern oursevles with the
question of whether it is a requirement (that seems to be agreed).
If we cannot agree on a uniform way to handle these cases for the
big batch of tags we'd like add, based entirely on the data from
the standards from which we're importing this information, then
I suggest that those details would most properly be hashed out
on the ietf-languages list on a case-by-case basis.

Randy

I'd put this differently. Given macro ID "xxx" and encompassed micro ID "yy=
y":

1. There is no direct connection between primary subtags "xxx" and "yyy"; a=
 connection would have to be maintained by tables in matching processes. Bu=
t, if "yyy" always required "xxx" as a prefix, then that relationship is ca=
rried in the tag itself, and because truncation gets used in matching (it's=
 part of basic filtering, extended filtering and lookup in 4647), a relatio=
nship falls out from the matching process.

2. The relationship is important because there is a significant level of ex=
isting usage of "xxx", and we want to allow for future usage of "yyy".

The point about existing usage is significant here, I think. If "xxx" and "=
yyy" were introduced at the same time and users adopted "yyy" while "xxx" n=
ever took off, then there's no particular need to relate them. But if both =
are going to get used (i.e. "xxx" would get used apart from "yyy", and "yyy=
" would also get used -- whether that is with or without "xxx"), then we pr=
obably want the relationship to be captured.

A.2 may be a little more than JAC can guarantee. The idea I worked with is =
that macrolanguages are coded because in some application the group of micr=
olanguages are being coded as one -- they are not distinguished. Presumably=
 that would happen because they are mutually intelligible, though that may =
not always be the case.

I don't assume that Mandarin and Cantonese are mutually intelligible at a f=
unctional level (though perhaps in their written forms they may be); approp=
riately or not -- perhaps an accident of history -- a single ID "zh" has be=
en used for both. What we need to do is to be able to relate *as appropriat=
e* "zh" content with "Cantonese", "Mandarin", etc., or Cantonese, etc. cont=
ent with requests for "zh". Similarly for other cases in which -- for whate=
ver reason -- things are, in practice, sometimes split but sometimes clumpe=
d.

Of course, this assumes that for macro/micro cases there always *is* one va=
riety that can be considered *the* major variety.

When Gary Simons first began to analyze 639-2 with a view to how to map it =
onto Ethnologue, the original operational principles we established looked =
for just that -- we referred to it as the "major language variety (MLV) pri=
nciple". (See http://www.sil.org/silewp/2002/SILEWP2002-004.pdf, page 7.) T=
he idea was that we would equate the existing 639-2 ID with *the* major var=
iety, when one could be identified. Of course, we immediately encountered a=
 reality that there isn't always *one* major variety. See http://www.ethnol=
ogue.com/14/iso639/analysis.asp#U for cases we found in our initial analysi=
s that we could not resolve.

I had expected we would try to work with the JAC to come up with some resol=
ution for those cases. That was until the macrolanguage concept occurred to=
 me. And a key thing that prompted it was the pre-existing IANA registratio=
ns involving zh: we could not equate "zh" with Mandarin because in existing=
 usage it was clearly being used for Mandarin, Cantonese, Minnan, etc. An a=
vailable alternative was to consider "zh" to be a collection (and that was,=
 in fact, what we did in our initial analysis), but that just didn't reflec=
t the way it was actually being used: "zh" was in widespread use as though =
it represented an individual language. Somehow, I had to marry those two: i=
n use as though it represents an individual language, but also in use for m=
ultiple languages. Hence the prototype for macrolanguage.

Now, you're introducing the possibility of having the one-language/many-lan=
guage dichotomy while also maintaining the MLV principle. (Of course, the m=
ost widespread use for an *individual* language would have involved for Man=
darin.) Of course, that's not formalized in 639-3, but that doesn't block i=
t from being a useful idea. One issue that would need to be worked out is w=
hen "xxx" as an individual language is the MLV-preferred microlanguage, whe=
n it's the undifferentiated group of microlanguages, or if this difference =
matters in practice.

But there's also the other issue: not all macrolanguages have one microlang=
uage that's clearly picked out by the MLV principle.

It may help to consider realistic scenarios for future changes in 639, real=
istic scenarios for usage of language tags, and weigh the value of comparis=
on between two different tags that may be used for comparable content.

If there is a real expectation that this will happen, this
will be critical to the extlang discussion, due to the
implications for stability in encoding.

Is there a possibility of an encompassed language getting changed not to be=
 encompassed? If "xxx" is a macrolanguage and "yyy" an encompassed "microla=
nguage" (to use Mark's term), I could perhaps see "xxx" getting deprecated,=

I don't see why.  Stability says that once a language subtag,
always a language subtag: nothing is demoted to extlang subtag
status.  So languages that are encompassed in 639-2 today
have the same status (language subtag) as languages encompassed
in 639-3 later on.

The more serious case is when an encompassed language is no
longer encompassed or its macrolanguage is changed.
We'd be free to change the proposed Macrolanguage: field,
but the Prefix: field and Type: fields would have to remain.

Human error would be the obvious candidate.  "Oh, we thought Foovian
was part of the Slobbovian macrolanguage, but that was because Dr. X
put the wrong code on the form back in 2008."

Hello Mark,

I seem to remember that you said that you tried to implement them
at Google and found them difficult. But I don't remember you having
explained what exactly the problem is. If you have explained that,
could you point to the relevant message? If not, would you care
to give some more details?

It's not a MUST, it's a MAY.  Matchers are allowed to take into account
any information outside the purely syntactic match algorithms that they
happen to have -- and find useful  For example, a fallback from Scots
to English probably makes sense everywhere -- if you know Scots, you
know English.  On the other hand, a fallback from Swedish to Finnish
would be a Really Bad Idea, except within Finland, where it might make
all the sense in the world.  (Falling back from English to Scots or
Finnish to Swedish essentially never makes sense.)

So while there is no reason to prevent such nonsyntactic matching,
and 4647 explicitly licenses it, there is no reason to require that
every matcher use it either.  The point of the extlang tags, like their
currently-grandfathered predecessors, is to make additional matches easy.

Agreed.

Two caveats: (a) fallback is one-way, so *mutual* comprehensibility
is not required; (b) Mohawk and English aren't comprehensible at all,
mutually or asymmetrically, but it so happens that the few hundred
Mohawk-speakers know English too.

Also, fallback is a matter of best effort; it does not have to work in
every case to be useful in many cases.  In particular, a failed fallback
leaves you no worse off than before.

Not necessarily all, though the more the better, of course.

Of course that's not the case, as you must know.  Even if true in any
particular case, "every speaker" is an inappropriate standard.  If there
are one or two ancient Mohawks who don't have sufficient command of
English, it can't be helped.

"Hunky-dory" is the wrong standard.

This doesn't differ much from Option A, except that it changes the
semantics of macrolanguages in a way inconsistent with 639-3:

Otherwise my comments above apply.

True enough, but it disregards the behavior of the large number of
naive matchers already out there that lack nonsyntactic information.
It also disregards the well-chosen grandfathered tags (which will become
for the most part redundant in 4646bis along the current lines), which
were picked precisely because they worked tolerably, if not perfectly,
with naive matchers.  This is the primary argument for using extlangs:
they are a conservative extension of what has already been done and what
tags have already been assigned to documents.

Your argument also proves too much: we find it useful to fall back from
az-Cyrl, az-Latn, and az-Arab to plain az (or vice versa for filtering)
without requiring that these be mutually intercomprehensible (your
Option A) or that one of them is the standard (your Option B).  The
results may be less than ideal, but we live with it.

> We and everyone else already have to deal with equivalences with

Again, every one else does not *have to* deal with them; they MAY
treat them just like all other tags, at the expense of missing some
reasonable matches.  4647 makes such matches entirely optional.

It's true, as Dr. Johnson said: "Of an opinion which is no longer
doubted, the evidence ceases to be examined."  I've done my best above.
But I don't understand yet how extlangs make BCP 47 worse, and I think
they actually help given legacy documents and legacy matchers.

As one of the people who got this thread started, I'm not ignoring it or 
anyone's position on it.  Things just suddenly got very busy for me.  I 
promise (or threaten, depending) to jump in as soon as I have more than two 
consecutive minutes to think about it.

That is exactly what I'm doing, and thank you for bringing it up.  In RFC 
4645bis, existing records may be changed slightly to add language names 
listed in ISO 639-3, and to put the 639-3 "reference name" first, but in no 
case will the Added date of an existing record be changed.

Thanks for the comment on RFC 4645bis -- there have been very few of those 
up to this point!

Is it already the case with 4646? Yes, according to section 3.4.
"Stability of IANA Registry Entries"

But, yesterday, the subtag baku1926 was modified (change in the
Comments) and the Added field *was* modified, from 2007-04-18 to
2007-04-20, which puzzles me (why changing it and why for a date two
months in the past?)

IANA's blunder or ambiguity in the procedures/RFCs?

No, I was not suggesting it myself but it is a good opportunity to
discuss it.

It seems reasonable to enumerate a macrolanguage "members "in the
macrolanguage itself. But I see some issues with this proposal:

1) What will be the stability rules for Encloses? Can an extlang be
dropped from a Encloses field? (if advances in linguistics show that
it was wrongly added here, for instance.) And can an extlang be added
to an Encloses? If yes (which seems reasonable), it means that the
macrolanguage entry can change quite often (consider Zapotec with its
dozens of enclosed extlangs).

2) It introduces a redundancy in the registry, an information which
was already there and could be computed from other records. Randy
Presuhn noticed it can be seen as a good thing ("it should be flagged
in its record, rather than requiring it to be computed by examining
all other records"). But more redundancy means more possibilities to
introduce contradictions.

3) 4646bis does not indicate an upper bound for the length of a field
("The content of this field is not restricted, except by [...]
reasonable practical size limitations."). Zapotec's "Encloses:" will
be at least 232 bytes long and sign langauges will be worse. While
there is a long discussion of length issues for tags, it seems there
is none for registry-parsing applications. I suspect that some of them
may have hard-wired limits for field lengths.

I am wondering if something on mis and the time frames in which 639-1,
639-2, and 639-3 apply can be added to the specifications describing the
matching of language tags???

The trick would be for applications to note the date on which content was
tagged, and then apply 639-1, 639-2, or 639-3 according to the date;
content creators would of course need to include in their documents the last
date each was updated.

Maybe this could be incorporated into the standards for matching language
tags???

(If anyone else thinks so??? )

Apparently an error in the second record that was sent to IANA, the one with 
Resat's replacement transcription.  IANA perfectly reproduced the record 
they were sent.  We'll ask them to fix the mistake.

You can't get much less ambiguous than this:

It's informative and thus could be changed. However, extlangs are 
permanent and stable (including their Prefix relationship), so they 
cannot be removed. Note that Encloses describes the function of the 
subtag, not necessarily the linguistic relationship (although in 
practice we hope that both are true).

I would assume that an extlang can't be dropped from Encloses, since 
stability rules prevent the Prefix or status of an extlang from changing.


  And can an extlang be added
> to an Encloses? If yes (which seems reasonable), it means that the

You mean a new extlang? Of course new extlangs could be added as ISO 
639-3 assigns new codes. But there is no such thing as an existing 
extlang acquiring a new Prefix (and thus a new Encloses relationship). 
It is banned by stability rules.

The extlang records have a computable relationship. The main problem 
will be grandfathered primary language subtags that are enclosed by 
other subtags linguistically but not in terms of tagging practice. That 
is, not all possible macrolanguage relationships are described by or can 
be computed from entries in the registry.

There isn't one.

Note that some comments approach or even exceed the sizes you note above.

I would tend to propose that we make Encloses a single field with 
structure simply because I find the multiple repetition of the same 
field unaesthetic. Of course, we went the other direction with Prefix, 
so there is some precedent for repeating the field.

I'd like to get a feel for what the concerns are about using UTF-8 for
subtag registry. Based on my testing locally, that works fine on IE, and
firefox (the latter both on Windows and Linux). If anybody happens to
use a shell or shell client that can't handle UTF-8, all they have to do
 when they see a mangled character is use one of many different clients
that can handle UTF-8. There's hardly any problem, as far as i can see.

P.S. I'm not a member of the list, but i'll try to track it down thru
http interface.

I guess there is already software that can read the subtag registry as
it is today, but i think if it was XML based, the whole process would
work as it were on steroids, especially in the long run. Then one could
use streaming XML APIs, and XSLT to read the registry.

I'm not doing a schema for this sample just yet, but a sample of what
they could look like follows below. One could have a parent element of
Prefixes for an array of Prefix elements, but i think it could also be
represented w/o it, as shown below.

The issue is that email is an essential part of the process, and
guaranteeing that email gets through the whole of the infrastructure
unmangled is still difficult.

A UTF-8 registry doesn't require that the format used to communicate
additions and changes also be UTF-8.  I think the real question is that
of how much one is willing to rely on the good folks at IANA to handle
the translation of whatever the updates look like into UTF-8.

Quite.  My notion is that the less IANA has to do (considering what
all else it has to do), the better.

Hoi,
It happens often that exactly because of the content is NOT UTF-8 that I get
the information mangled. With UTF-8 you either get the message or it will be
indicated that you have insufficient fonts installed. The notion that the
current encoding always works is wrong.
Thanks,
    Gerard

It always works for ASCII text, and the Registry is restricted to
ASCII text.

Hi -

As co-chair...

We've had this discussion  several times.  As long as there is
an insistance that the format for the communication of updates
is the same as that of the registry itself, I'm pretty sure the conclusion
won't change in the forseeable future.  Just on this list, we've all
seen the picturesque results of various incompatible mailers
(and even different configurations of the same mailer) mangling
what should be simple UTF-8.  Unfortunately, it doesn't appear to
just be a question of having the right fonts.

If this thread is to move forward to a different conclusion, the only
path by which I can see it succeeding is to recognize that the
email communication of changes might have to rely on a different
coding of non-ASCII things from what the registry itself uses.
 If we can agree that the existing email format is adequate for purposes
of communicating changes, then there are three decisions needed:
    (0) do we want to stick with email as our mechanism for communicating
          updates?
   (1) is a UTF-8 registry indeed desirable?
   (2) if so, are we willing to allow IANA to convert the apropriate bits
        of an update directive conveyed in ASCII into the "real" code points?

But please, let's not rehash the discussion we've already had.

Randy

The question is: can the LSR and/or his/her proxy (i.e. Doug) manage to 
send email to IANA encoded as UTF-8. All other emails are "nice to 
have", but not required. I think the answer here is that they can manage it.

The "compelling reason" against UTF-8 that I've seen has nothing to do 
with email or browser availability or IANA's skill set. It is simply 
that it is a change in the registry format and could break existing 
implementations that rely on the ASCII format.

As the original (and long time) proponent of a UTF-8 registry, I find 
that argument to be the one sticking point for which I cannot find a 
good counter argument. If we change it, we will have to make a conscious 
decision to break with the past on that point.

I note also that UTF-8 has failed to reach consensus on at least three 
separate occasions.

I think we should close this discussion. We're unlikely to make it 
further this time than last. I think UTF-8 is desirable and the 
procedural points can be solved to deal with it. But I don't think we'll 
find consensus down this path (or at least consensus that doesn't have 
multiple loud objections). Ditto on the XML proposal.

No need to dream, it is already there (and in many other formats,
too).

Your schema seems quite clsoe to mine
(http://www.langtag.net/registries/ltru.rnc) and I suggest that people
interested in moving this schema from the current draft to a "real"
schema, production-ready, gather in private since XML work is not well
received on the LTRU list.

Isn't it a problem that there is no way to know the modification date?
Should we work on a Modified: field in the registry?

I ask so because the LSR syndication feed
http://www.langtag.net/registries/lsr.atom would certainly benefit
from it. Its format, Atom (RFC 4287), makes a difference between
<published> and <updated> (other syndication formats do it as well).

For UTF-8 and XML, a possible path is to have unofficial,
automatically produced, copies of the registry in other formats (see
http://www.langtag.net/registries.html). It would solve most of the
use cases.

XML is already there, UTF-8 is certainly possible (any volunteer to
write the program?)

Yes. 

With Encloses: or a similar field, adding a new record (the new
extlang) will change *another* record (its macrolanguage), which is
questionable.

I don't think it's questionable. Inserting a new record that obsoletes 
an existing item can cause deprecation, change from 
grandfathered->redundant, or other changes.

It *does* mean that inserting an extlang requires two records to be 
submitted to IANA, instead of just one.

Ultimately, though, the question is whether having the information adds 
value in the registry in proportion to the disruption that adding more 
fields, maintenance rules, and so forth adds.

No. The text on langtag.net is wrong.

Grandfathered tags are always legal. These particular ones may become 
redundant (assuming Mark's idea of not implementing extlangs doesn't go 
forwards). But they'll always be legal.

I think what Stephane means is "tags which would otherwise be illegal 
but are maintained for compatibility".

The ISO 639 committee intends (as far as I understand) to remove
"(Other)" from these, widening them.  It will of course
remain best practice not to use them if more specific coding is
available and known to the coder.

The statement in the last clause is only partially true.
When I made an attempt at a consensus call on this issue (many months ago),
my recollection was that a slight majority of the people responding
favored moving to XML, but that that majority wasn't strong enough
to make the change, in particular because the people who would have
had to do the actual work (read: editors) weren't very excited.

It is true that if we stay with the current state (no XML), then
we shouldn't use the list to discuss XML, because we want to
concentrate to get our documents out.

Regards,    Martin.

When it is argued that the content should be in ASCII in order to be
readable, then please make it so that the content of the website parses
well. I get for instance "Ethiopic (Ge&#x2BB;ez) / Ethiopic (Ge'ez)". This
is nor humanly readable.

To me this notion that UTF-8 cannot be used because it might break
things is rather odd when I cannot properly read all the names of
scripts on langtag.net. To me it seems that things are broken anyway.

Thanks,
    Gerard

Do you prefer:

Ethiopic (Ge'ez)

only? 

If so, I can create an ASCII file where all descriptions with numeric
entities omitted. There is no general way to translate from these
entities to ASCII (that's why Unicode was invented, after all).

And note that, in scripts only, four subtags have no pure-ASCII
description (Hano, Nkoo, Lepc and Hang) so this would mean not only
selecting some descriptions but also parsing words inside
descriptions.

[Side note: the registry seems a bit inconsistent. Why:

Subtag: Ethi
Description: Ethiopic (Ge&#x2BB;ez)
Description: Ethiopic (Ge'ez)

and:

Subtag: Hang
Description: Hangul (Hang&#x16D;l, Hangeul)

Why not:

Subtag: Hang
Description: Hangul (Hang&#x16D;l)
Description: Hangul (Hangeul)

?

I would be glad to provide plain-text UTF8 versions of the registry as
soon as I have time to write the program. Since langtag.net is a
cooperative effort, any cooperation is welcome (probably better off-list).

As remarked recently in a different thread, applications are allowed
to use additional knowledge when matching.

The main problem with the idea proposed below seems that it relies
on information external to the language tag, information often not
available at all (in HTTP, there are quite some dates, but none
of them may be the date on which the language tagging occurred).

If enough people (which wouldn't include me) really care, this might
be an area for an extension. With 8 digits per label, a 'date' extension
would come out rather nicely (ignoring for the moment the y10k problem :-):
   mis-d-20070622
(assuming this extension gets the letter d).

Regards,   Martin.

Before we kill this off too quickly...

I don't remember all the discussion from the last time around, but seems to=
 me we at least have identified a small set of core issues:

1) Would UTF-8 be desirable (all other things being equal)?

2) Is such a breaking change in the registry acceptable?

3) Does the content of a registry edit have to be exchanged in email bodies=
 on IETF-languages and be in the same encoding in those emails?

Randy broke 3 into two parts, which I'll modify slightly:

3a) Do we need or want to stick with communicating proposed registry edits =
solely in the body of emails?

3b) If "yes" to 3a, then can we use a different representation in discussio=
n on IETF-languages and depend on the LST Reviewer (or his assistants) and =
IANA between them to convert the content as needed?


I think there is consensus on 1. If we are willing to discuss this a bit fu=
rther, it might be helpful to focus on 2 before 3.


Wrt 2: Non-ASCII content would appear in certain attribute fields accompany=
ing a subtag: only in description or comment fields. Would there really be =
parsers that make assumptions about the content of these fields, or that as=
sume only byte values within the range 0x20 - 0x7E would be encountered?

OK, looks like you guys have it covered. I would just prefer using XML
Schema for schema, because i think it's the most standard way, and while
i'm not an XML guru per se, it is likely to be the most powerful as well.
Also, it might be worth considering supporting multiple languages for
some textual elements (by requiring a lang attribute), as in:
	<Description lang=3D"en">
	Unified Turkic Latin Alphabet (Historical)
	</Description>

For what it's worth, i'm ready to vote for XML. Lemme know if you folks
ever need an extra vote.

It is neither the most standard nor the most powerful.

Well, i think for me the interest is whether the next release could
mandate UTF-8, so that we don't have to deal w/ escapes.
I guess there are 2 issues:
1. Email clients
2. Browser clients

On 1:
If you can see s w/ cedilla on the first line above, then your email
client handled UTF-8; if not maybe you could try choosing UTF-8 encoding
manually. I know that Thunderbird and Outlook don't have a problem w/
UTF-8. What other email clients are we talking about? If your pine
client thru your shell can't handle it, then really you will only have
few characters mangled, because charactes overlapping w/ ASCII are
rendered the same whether it's UTF-8 or ISO-8859-1. Then you still have
an option of using another email client to UTF-8 appropriately when you
really care.

On 2:
I don't think any up-to-date browsers have any problem w/ UTF-8 (IE,
firefox, seamonkey, opera). The only ones that would have problem could
be cell-phone based ones that don't belong to one of the brands above
and some shell-based ones, which probably depends on what shell is being
used. And then again i'd say it's not a big deal, because you can use
another client to read stuff if you care. Besides the pros of not having
to deal w/ escapes outweigh the cons of not having UTF-8 support on some
cell-phone devices and some shells.

So what exactly email and browser clients are we talking about that
don't support UTF-8? If it's only a matter of email, we could say: "when
using email, you can send requests using escapes, but these escapes will
be posted in UTF-8 in the registry"? If we adopt UTF-8 for new
submissions, we could also say "starting on <someDate/> all character
escapes in the registry will be converted to UTF-8."

Most importantly, if UTF-8 is going to be easier for 95% of mainstream
users, couldn't we tell 5% of peculiar users to deal w/ it? The registry
for the internet should probably be based on up-to-date technologies,
rather than trying to accommodate obsolete ones as well, which i think
are used to rarely to be cared about anyway.

Hi,

A suggested refinement to 3b below:

* Email discussion remains 7-bit ASCII with some escape
  convention.

* LSR (and helpers) send all official approved updates to
  IANA as plaintext email in US-ASCII with an attachment
  of the UTF-8 text for cut-and-paste into the Registry.

The necessary effort to use the ASCII to UTF-8 conversion
tool is moved back into the LSR's scope.

Hmm?

Cheers,
- Ira

<...snip...>

3) Does the content of a registry edit have to be exchanged in email =
bodies on IETF-languages and be in the same encoding in those emails?

Randy broke 3 into two parts, which I'll modify slightly:

3a) Do we need or want to stick with communicating proposed registry =
edits solely in the body of emails?

3b) If "yes" to 3a, then can we use a different representation in =
discussion on IETF-languages and depend on the LST Reviewer (or his =
assistants) and IANA between them to convert the content as needed?

I think there is consensus on 1. If we are willing to discuss this a bit =
further, it might be helpful to focus on 2 before 3.

I just read the updates thru http, and i agree w/ Randy and Addison's
idea of converting escapes
to UTF-8 after the email phase. The submitter can always verify the
correctness thereof thru http,
and object if there are any mistakes. If this is done by a little
program, that is written w/ some unit tests, and tested, then errors
should be minimal.
As far as passivity, if this takes effect w/ the next release of the
registry spec, and people know about it in advance, then it's natural
for it to not be passive. For temporary passivity, the old registry
could continue to exist w/o updates at the existing URL, and the new
registry to be updated could be exposed thru a new URL.
That happened in java betweem 1.3 and 1.4, and 1.4 and 5: it's
inevitable at early stages, and maybe even beyond. Deep down, do we not
all know that it will be UTF-8 and XML at some point? I think we do, so
passivity question will come up anyway, it's just a matter of managing
it well.

Yes, it's an option as a work-around, but it being unofficial will cause
people to avoid it most of the time.
Some notes:
http://www.langtag.net/registries/language-subtag-registry.xml
this has missing comments.

http://www.langtag.net/registries/language-subtag-registry2.xml
This shows UTF-8 and XML together quite well, although i'd lean towards
making tag an element rather than attribute.

- From baku1926 in the latter, does it seem to you redundant to have ASCI=
I
escapes next to UTF-8? I think it seems redundant to me, despite some
really made up characters in that alphabet.

I though nobody would notice :-) Anyway, it was simple to fix. Done.

[Aaahhh, the famous "element vs. attribute" fight of every XML-related
discussion :-) ]

There is no official XML schema for the LSR. If some people are
interested, we can set up a group to try to define one?

Standard? In what way? RFC 3470 "Guidelines for the Use of Extensible
Markup Language (XML) within IETF Protocols" does not give it any
special status. Some RFC use W3C XML Schema (RFC 4931), some use
another schema langage (RFC 4287).

Even at its birthplace of W3C, they now use Relax NG for some
standards (http://www.w3.org/TR/SVG12/).

Sorry, as you say, you are not a guru. One can say many things about
the strengths and weaknesses of the various XML schema languages but I
believe that there is a clear consensus that Relax NG is by far the
most powerful.

This is not possible for the recordjar2anything converters because the
information is not, unfortunately, in the registry.

I assume that if the extlang mechanism were abolished, then the special-case 
handling of "sgn" would not occur either, and American Sign Language would 
be indicated as simply "ase" (not "sgn-ase"), and "sgn-US" would be 
deprecated in favor of "ase".

I'm doing a lot of catching up, which means reading over a lot of material 
that others have already replied to.  So I apologize in advance if I rehash 
anything that's been decided.

Mark Davis <mark dot davis at icu dash project dot org> quoted John Cowan:

That isn't fair.  I doubt it could be said of any standard, or 
specification, or protocol, that every conceivable implementation 
ramification has been fully explored.

I agree with John on this point.  We did have an excellent idea of what ISO 
639-3 would be like by this time.  There have been virtually no structural 
changes in 639-3 since Peter originally formulated the extlang concept and 
we discussed it.  Of course somebody will have missed a detail somewhere, 
but we had the general idea.

I can see value in this approach, because I can see value in updating my 
implementation.  But we have shed so much digital blood over Suppress-Script 
on the basis that matching implementations won't be smart enough to match 
"nl-Latn-NL" with "nl-NL", and won't be updated to do so, that I continue 
not to understand why we should assume any will be updated to fall back to 
macrolanguages.

I have a real problem with the idea that tag producers should be encouraged 
to tag Cantonese as "yue", thereby drastically reducing the likelihood that 
tag consumers searching for "zh" or "zh-yue" will find it.  The outcome of 
such an scenario will be that tag producers will be reluctant to use the new 
4646bis subtags in general, and may ignore other changes from 4646 to 
4646bis.

I feel as though we are recanting what was said on ietf-languages at the 
time "zh-cmn" and friends were registered, that they would eventually become 
generative tags and wouldn't add to the grandfathered-redundant slag heap.

My case for extlang is that it allows simplistic RFR matching engines to 
retrieve "zh-yue" content when handed "zh", but still identifies the content 
as Cantonese for more sophisticated matching engines that can take advantage 
of extlang.  It puts the additional burden of identifying the content on the 
tag producer, where it belongs, not on the tag consumer.  The 
Suppress-Script argument shows that we don't trust tag consumers to be very 
sophisticated.

But there is no sense in having a Macrolanguage field unless we define a 
specific use for this information in 4646bis.  Just saying "this language 
has a macrolanguage" (or alternatively, "this is a macrolanguage that has 
this list of encompassed languages") doesn't add anything to tagging.  Some 
months ago I suggested a Language-Type field that would reflect the ISO 
639-3 classifications, and several people pointed out that it didn't add 
anything to tagging.

I don't like this, for at least two reasons:

1.  If the goal if to facilitate matching, then the direction of fallback 
ought to be from "yue" (or "cmn", etc.) back to "zh".  It doesn't make sense 
to put the fallback information in "zh" in that case.

2.  As Addison noted, we already have a precedent for using multiple fields 
to indicate multiple Prefix values.  I see no point in putting multiple 
values in a single "Encloses" field and introducing a new comma-separation 
convention for just this field.

I would be happy to jump through whatever hoops are needed to get the 
Registry established and maintained in UTF-8, if that is the wish of the WG. 
Certainly I can send mail in UTF-8, and even if I couldn't, I could attach a 
file.

I believe other people in the WG had arguments against a UTF-8 Registry.  I 
suspect they are using systems or applications that are not fully 
Unicode-enabled.  I would like to reiterate that browsers and fonts are by 
no means the only parts of a computer system that determine whether UTF-8 is 
supported or not.

This is true.  RFC 4646bis could specify that either UTF-8 or hex escapes 
are acceptable formats for the Registry, which would allow new 
implementation to read old copies of the Registry, but I don't know how to 
solve the reverse problem (if such it is).

One problem is that it's been conflated with other issues, such as XML  I 
applaud Randy's efforts to separate the discussions and get each question 
answered one by one.

We should first make sure we understand the purpose for adding this 
information.  We have an Added date so that tag users can see which subtags 
were available at any given time.  But because of certain stability measures 
we have taken, once a subtag is added, it should always be valid from that 
point on, with essentially the same meaning.  A Modified date might imply 
that the meaning of a subtag changed on that date, which isn't supposed to 
happen.

I split these out in draft-ietf-ltru-4645bis-01:

Subtag: Hang

Description: Hangeul

Just load the Registry into any editor that can convert hex NCRs.  Both 
UniPad and BabelPad can do this; there are probably others.

I'd like to suggest that the other "distilled" data at langtag.net be 
similarly converted from hex escapes to real Unicode characters.  The 
Registry contains hex escapes because it has to, not because the country 
denoted by CI is really called C&#xF4;te d'Ivoire.  As long as you're doing 
one type of processing, you may as well do the other.

Done for the tab-separated text files and for the SQL files.

UTF-8 SQL files have been tested with PostgreSQL and work fine.

Anyone to test tab-separated UTF-8 text files with MS Excel or a
similar tool?

I did not convert the XML files, because any XML processor is supposed
to read hex escapes.

Sorry, it's not quite trivial; I cannot produce the escape sequences for 
those utf-8 characters I cannot get to display (I'm sorry to say there is no 
way here!

Seriously we do not have the fonts available on most library computers; and 
no, patrons  are not authorized to download any updated fonts for viewing 
characters, or an updated browser, etc.

You Geeks forget that not everyone has internet access at home! or works 
from a work computer!  in the U.S., in a lot of places, people use the 
internet at the library; they have Microsoft Windows, games, music at home, 
but not the internet!

I've tried to set my browser to unicode encoding--when it's available; I've 
set my font to Lucida; I cannot get the characters people include in 
documents
to read but ??? and the little rectangles;
what else can I do???
Thx.

(Thus, while I like the utf-8 version of the registry you now have, I hope 
you will keep the ascii version with the escape sequences
http://www.iana.org/assignments/language-subtag-registry

and that we will add to it the transliterations!

Another option:

(1) encode an html version, using the escape sequences in the text source

make sure to point to the fonts that most people do not have (see:
http://www.w3.org/International/questions/qa-utf8-upgrade

"Fonts not available in a standard installation can often be downloaded from 
free sites by users, and you can point to those sites from your pages. It is 
not desirable to embed fonts in pages because the technology for that is 
proprietary and browser-specific.")


(More Notes:

http://www.w3.org/International/questions/qa-utf8-upgrade
"Although many mobile phones support UTF-8, some do not. "

Also older Windows operating systems do not support Unicode.

The IESG will solicit nominees for the position (upon adoption of this
document or upon a vacancy) and then solicit feedback on the nominees'
qualifications.

Qualified candidates should be familiar with BCP 47 and its requirements; be
willing to fairly, responsively, and judiciously administer the registration
process; and be suitably informed about the issues of language
identification so that they can draw upon and assess the claim and
contributions of language experts and subtag requesters.

Does "adoption" mean "IESG approval" or "RFC publication"?
Is the intent to cause the position to become vacant upon
approval, until the IESG is able to make an appointment?

"claim" -> "claims" ?
