Uhm... I see no reason why that should be the case. It's an
implementation detail really, but just for an example, CERN-style
meta files have been around for like 10 years; if using Apache you
can also use mod_asis, even though it's not optimal. Or even if
using static files you could pass all requests through a script
which determines the appropriate charset via your preferred
mechanism, and adds it to the MIME headers.

This is exactly the reason why I think no change is necessary. If
you are in a MIME environment, use MIME. If you are not, you MUST
use UTF-8. I think this is quite reasonable in fact.

You see - implementation errors. ;-) Even for clipboards, you do
have a choice - you can trancode to UTF-8 before sending the data
to the clipboard, i.e. before throwing away the charset information.

I agree with you that it would be nice to be universally compatible;
however, I don't think that should be done by compromising on the
present clean specification - expecially since I still haven't seen
a single example where implementations could not do The Right Thing (TM)
within the standard.

Absolutely not, they should convert everything to UTF-8. I honestly
can't see the reason for NOT doing that - since any conforming
implementation MUST be able to handle at least UTF-8, why go to
the effort of using anything else as a native charset? I mean I
can see the need to import or even export data in different
charsets, but UTF-8 should be the main one.

My web server doesn't support CERN-style meta files.

mod_asis is not supported by my web browser, and even though I agree it would 
serve the purpose of providing the MIME headers I still do not like the fact 
that requiring MIME breaks the fundamental encapsulation of iCalendar.

You could, but imposing that as a restriction to using iCalendar is not 
reasonable.

Again, the fundamental objection is: 2445 should work equally well outside of 
a MIME environment.

I mostly quite like that.
Unfortunately 2445 does not agree with us. 
Instead of a CHARSET property would you agree to rewording 2445 so UTF-8 MUST 
be used if not in a MIME environment?

Oh? You are going to expect all past and future software to do this? 
Notepad.exe for example?

The examples are endless: FTP for example, notepad editing a 2445 document and 
pasting to clipboard for another. Perhaps more importantly the possibilities 
are endless because not all environments are MIME environments.

This is a quick note to get a count of who will be at the IETF meeting in 
San Francisco.  If you are going and plan on being at the CalSch session, 
let us know.  Also, we will do our traditional Monday night dinner and 
meet in the lobby of the hotel around 6:30 pm.

That is not going to happen ether as several asian countries charsets
are more efficient then UTF-8 for them. We did not pick UTF-8 and the
wording in 2445 at random. It was discussed over a few years and agreed
upon. Changing 2445 in an incompatible way is just not going to happen.
If we changed it to a MUST it would make currently compliant applications
non compliant. Do you think they are just going to ignore that issue?

It is *not* the job of an interoperability protocol to be view-ready.
It is the job of an interoperability protocol to be interoperable
with multiple venders across multiple countries. Your OS tool specific
example is not relevant. The point made was that you can write
code to do copy/paste, do it or not but do not expect every
vendor to agree that they have to change.

Your point is not relevant to iCalendar as FTP and Notepad.exe were never
designed to be iCalendar aware as was an endless list of other unrelated
software.

Just because you do not want to write code to translate charset does
not mean the rest of the iCalendar compliant vendors should break
their code to make you happy.

If you have suggestions that can extend or make it more useful, great.
But making a new version of 2445 break or make non compliant existing
implementations is not going to happen.

Others have pointed this out to me too. I agree we can't force UTF-8.

My opinion is that 2445 should encapsulate charset so we can work outside the 
MIME environment, as mandated by the spec.

It is relevant because iCalendar states that it should work outside of a MIME

It is wrong of you to make this personal. It is wrong of you to publicly state 
that I want or do not want to do something when you have absolutely no idea 
what my reasons or intentions are.

Peace...

Perhaps it is me. Perhaps I just do not understand one single sentence in 
2445:

"However, the format in this memo is equally applicable
   for use outside of a MIME message content type."

Because of this, I maintain the spec is broken because the format will not 
work without a CHARSET property.

All arguments seem to be based around, "use MIME". But this is in conflict 
with the sentence above.

I see multiple organizations taking advantage of this to break 
interoperability in various ways (from calendar clients and servers to cell 
phones) and I feel it is only going to get worse.

There has not been a single better proposal than the CHARSET property for 
fixing the above statement.

I agree with Mark Swanson, we should add the CHARSET property.  I had to 
modify Notes code to allow  the recipient to try different charsets on 
attached iCalendar objects.  The reason was that some phones in Japan can 
generate iCalendar.  However they are being generated in SHIFT-JIS.  They 
are sent as attachments to email.  As a consequence to this problem 
Notes/Domino 6.0 always inserts an X-LOTUS-CHARSET <inana-charset> as just 
below the BEGIN: VCALENDAR.  Thus, if it was generated as an attachment by 
Notes (i.e sending some sort of combined event such as conference), I 
absolutely know the charset.

I'm not clear on where folding whitespace is allowed.

My strict reading of it leads me to believe that

B
 E
 G
	IN:
 VCAL
 ENDAR
END:VCALENDAR

should be parsed the same as

BEGIN:VCALENDAR
END:VCALENDAR

I also don't see any minimum required sizes. Do I have to parse lines
up to 8k long? Longer? Are there any length limits on names or at
least minimums I might be required to preserve?

thanks,
Larry

What is the MIME header for the attachment? What is the Content-Type

Then that is the real problem not the fact that the object
does not have its original charset inside the object. You seem
to be talking about how you store the object in your application.

If you are electing to save it in its original charset then that
is fine. If you charset it to UTF-8, then you would not need it.

What do you do when you get a charset that you can not read without first 
knowing the charset - after ripping off the MIME header?

It looks to me as if MIME and iCalendar is working as documented.
Otherwise you would not know that it was SHIFT-JIS. And that
is what iCalendar + iMIP is about - it is already 100% portable - correct?

So despite the fact that you want to add CHARSET to the object,
your telling me that as an interoperability protocol - you did
not need it. How you store object internally (which is what I seem
to think you are saying) is out of scope for this working group.

This is a multipart message in MIME format.
--=_alternative 0074BC1B85256CDE_=
Content-Type: text/plain; charset="US-ASCII"

When you try to OPEN an attachment, you must pass attachment to registered 
handler for the attachment.  So attachment is extracted and handed off. It 
is no longer in MIME envelope.

Then that is the real problem not the fact that the object
does not have its original charset inside the object. You seem
to be talking about how you store the object in your application.

If you are electing to save it in its original charset then that
is fine. If you charset it to UTF-8, then you would not need it.

What do you do when you get a charset that you can not read without first 
knowing the charset - after ripping off the MIME header?

It looks to me as if MIME and iCalendar is working as documented.
Otherwise you would not know that it was SHIFT-JIS. And that
is what iCalendar + iMIP is about - it is already 100% portable - correct?

So despite the fact that you want to add CHARSET to the object,
your telling me that as an interoperability protocol - you did
not need it. How you store object internally (which is what I seem
to think you are saying) is out of scope for this working group.

I was going to disagree, but I reread 2445, and I think your interpretation is
correct.  I know that there are applications (e.g., MS Outlook) that treat the
sequence '\n ' as if it were a single space, but the example (sec 4.1, p 13)
makes it clear that '\n ' or '\n\t' should be removed as part of the folding
process.  I'm not sure what you're asking about wrt length limits on names
(what kind of names?), but as far as I can see, an iCanendar object can, in
theory, be arbitrarily large.

In order to guarantee interoperability, many specs would say something
like: 'A "name" can be any size. Implementations MUST handle names at
least 1024 octets long.'

This way implementations can protect against denial-of-service attacks
but there's a guaranteed size that will interoperate.

That is what your implementation does. It is not because
of iCalendar. Besides even if you are using some kind
of library or tool on your OS, I can't believe that
the MIME data is unavilable, if it were you would also
loose encoding and other information. Its your CUA,
and if not then intercept the MIME data prior to being
sent to the MUA and send it to your CUA.

Adding CHARSET to iCalendar objects will only make
it work some times for some implementations and only
when they try and guess the charset. Not a portable
solution.

    Lines of text SHOULD NOT be longer than 75 octets, excluding the line
    break. Long content lines SHOULD be split into a multiple line
    representations using a line "folding" technique. That is, a long
    line can be split between any two characters by inserting a CRLF
    immediately followed by a single linear white space character (i.e.,
    SPACE, US-ASCII decimal 32 or HTAB, US-ASCII decimal 9). Any sequence
    of CRLF followed immediately by a single linear white space character
    is ignored (i.e., removed) when processing the content type.

Yes - however it is typical to break at the normal CRLF.

You don't have to :-)
However your might get one.

Same as above

As long as it is syntactically correct it makes no difference.

   As long as it is syntactically correct it makes no difference.

This is easy for things I generate. If I am writing a calendar store,
I might try to store arbitrary objects generated by other
implementations.

The format in the memo is perfectly applicable without MIME. However,
the fact that your application works without MIME doesn't allow you to
disregard charset issues; rather, it puts the burden on you to make sure
you know how to interpret iCalendar data properly. This I think is the
spirit of the above sentence, and thus the spec is doing its duty.

You've been repeatedly citing the example of passing iCalendar data around
with tools which are unaware of MIME. That's fine, you can either convert
the data to UTF-8 or pass around external metadata. For instance, if a MUA
saves a part from a MIME message and then calls an helper application to
read it, it can either convert from the original charset to UTF-8, or it
can pass the charset as a command line argument (for instance).

What makes you feel those organizations will update their applications to
this new iteration of the spec you are proposing?

Sorry, I don't want to sound blunt, but since you're raising the issue
and advocating a change, the onus is on you to bring evidence for the
change, not the other way around. So far the hasn't been a single
example of something which is not working because of a flaw in the
spec instead of a vendor mistake.

That is what EVERY implementation does!

Doug, you're resisting changing iCalendar because of the deployed base 
of CUAs; but what about the much larger deployed base of MUAs? If we 
want to be able to use iMIP, we cannot require that MUAs be modified to 
transport iCalendar safely.

What is the local charset? POSIX, for example, specifies that locale 
settings are stored in environment variables, which means that charsets 
are per-process, not per-user or per-machine.

   Doug, you're resisting changing iCalendar because of the deployed base 
   of CUAs; but what about the much larger deployed base of MUAs? If we 
   want to be able to use iMIP, we cannot require that MUAs be modified to 
   transport iCalendar safely.

Having redundant and potentially conflicting character set tagging is
harmful, too. Once the character set also exists inside the MIME
object, all tools that might try to do a character set transcoding must
be aware of the iCalendar format.

If you want to go ahead with iCalendar having its own character set
tagging system, you should choose a MIME type other than
text/calendar so that processing systems do not default it to
text/plain.

I have already stated the example where this is happening.
Phones in Japan create iCalendars in Shift-JIS and attach them to email 
messages.  Because  by standard you are suppose to hand the attachment to 
the registered handler on an OPEN, the attachment processor no longer has 
any MIME charset information.

The format in the memo is perfectly applicable without MIME. However,
the fact that your application works without MIME doesn't allow you to
disregard charset issues; rather, it puts the burden on you to make sure
you know how to interpret iCalendar data properly. This I think is the
spirit of the above sentence, and thus the spec is doing its duty.

You've been repeatedly citing the example of passing iCalendar data around
with tools which are unaware of MIME. That's fine, you can either convert
the data to UTF-8 or pass around external metadata. For instance, if a MUA
saves a part from a MIME message and then calls an helper application to
read it, it can either convert from the original charset to UTF-8, or it
can pass the charset as a command line argument (for instance).

What makes you feel those organizations will update their applications to
this new iteration of the spec you are proposing?

Sorry, I don't want to sound blunt, but since you're raising the issue
and advocating a change, the onus is on you to bring evidence for the
change, not the other way around. So far the hasn't been a single
example of something which is not working because of a flaw in the
spec instead of a vendor mistake.

Do they set the correct charset on the MIME part?
If no, then it's their fault, and they should fix it.
If yes, then it's the MUAs fault for not handling things properly.

4.1.4 Character Set

   There is not a property parameter to declare the character set used
   in a property value. The default character set for an iCalendar
   object is UTF-8 as defined in [RFC 2279].

   The "charset" Content-Type parameter can be used in MIME transports
   to specify any other IANA registered character set.


Which to me means: unless MIME header says otherwise (or your app knows
better) the native charset is UTF-8.


So to get back to my message you quoted: this example doesn't show
a fault in the spec (IMO).

Bye,
	Andrea

No modification is needed in a MUA, they work already as MUAs do
support MIME.

That works if it works for the implementation. However there is no
such restriction as to the stored charset. Just because my application
is running in en_US.US-ASCII, does not mean that it can not read
in a binary blob of SHIFT-JIS and charset translate it to UTF-8
for storage. The user view and data storage do not have to be in the
same charset. Nether does the view and the transport charset have
to be the same.

No, it means that they can do charset translation an never be aware
of the content.

I do not follow your logic on that point. I can charset translate
any text/plain to any other charset once I look at the MIME header
charset attribute and never know or care about the formatting
of the contents.

I am not aware of any such 'standard' that says '...suppose to hand
the attachment to the registered handler on an OPEN, the attachment
processor no longer has any MIME charset information' If it exists
please post the standards body name and the name or ID of the standard.

So far it looks to me as if you are using an OS library that does
that for you. That however is your implementation decision and not
a MUA, MIME, or iCalendar restriction.

It is, however, a de facto standard, because that's what everybody does. 
 Nobody's told everybody to do it, but everybody has to accept the 
reality that everyone else does it.

Once again: MUAs don't do that.

Since no existing MUA does what you want, it is not legitimate to say 
that what you want is "handling things properly".  Any new standard that 
uses RFC-X needs to take into account the environment of existing 
implementations of RFC-X.  iCalendar has failed to do so.

False.  Once again: the step of transporting the attachment from the 
MIME body to the helper application is not MIME-based.  The only cases 
where the CUA gets the MIME headers are those where the CUA is part of 
the MUA.

No. Implementations may have failed, however many work and
they do not do it by magic. It it because there are ways
to get the information, MIME headers, and iCalendar attachments.

   No, it means that they can do charset translation an never be aware
   of the content.

   I do not follow your logic on that point. I can charset translate
   any text/plain to any other charset once I look at the MIME header
   charset attribute and never know or care about the formatting
   of the contents.

That's correct. However, if iCalendar objects ("text/calendar")
contained their _own_ charset information (via a CHARSET:utf-8
property or whatever) a naive conversion routine would not know to
update that property.

They don't have to do that. That's not their job. We are
talking about a calendar aware program which can also be an MUA.
You CAN send iCalendar attachments using any MUA that I have
seen. MUA's are not responsible for displaying video attachments
any more or less than iCalendar attachments.

No where in RFC 244[567] or CAP does it mandate or suggest
that MUAs be calendar aware. iMIP simply shows how to transport
iCalendar data using MIME. 'MUA' is only used once in 2447
and it is not talking about mandating that MUA be CUAs.

The one I use (mutt) does, as all Unix MUAs which use metamail. In fact
metamail has been handling this correctly for the best part of a
decade. Correctly, in this context, means it's able to (be configured to)
pass the charset as a command-line argument to any helper application
it calls.

That said, I'll readily agree that this is a niche application. Still
it show that SOME existing MUA chose to do it right.

I don't use Windows so I can't easily check it, but given that
Unicode has been the native format from Win NT 3.5 (or was that 4?),
it would surprise me if no MUA chose to convert from the incoming
charset to some sort of Unicode before passing the data to an
helper application.

Everybody does not do that. And my other point is still valid. If that
method does not work - don't use it.  There are methods that do work.

No, the method that SOME use might work that way. If it does
not work for you or your application - use another method.

I can extract the MIME headers on Windows and Unix from e-mail.
It is an implementation decission - not a problem in the specification.

In the area of calendaring - yes you need a CUA. Just like to view
video you need some kind of viewer. That is orthogonal to the MIME
header issue as there are methods that do work to get he MIME headers
with the attachements.

Would it be fair to say this: you feel it is up to non-MIME environments to 
come up with their own charset solution, while I feel this should be solved 
by having the document state its charset.

My reason is because there exists a number of applications that do not provide 
a charset solution, and I'm sure there will be future applications that do 
not provide on either. It would seem to me that 2445 would only benefit from 
encapsulating the charset.

No. Someone in Japan can't use notepad to edit a SHIFT-JIS iCalendar document 
and ftp it to me because I will not know what charset the document is in.

I believe people will follow the spec if they can. Also, if the IETF releases 
a new spec people will have no choice if they want to interoperate. It's the 
same reason people try to comply the best they can right now.

There must be a disconnect as there are several posted by more than one 
person.

But there is no good method to do so without the cooperation of the MUA.

I suppose there are some *bad* methods.  If you know where the message 
came from (e.g., a local spool or an IMAP server), and have access to 
that source (might be tricky, if the IMAP server demands a certificate 
and the CUA doesn't have it, or if the IMAP server doesn't permit 
simultaneous logins--some don't--or if it's a nonstandard message 
store), you might be able to search for text/calendar attachments and 
read the MIME headers directly.  It'd be disgustingly slow, though.

Right.  And anybody that implements a Proposed Standard needs to know 
that they might have to change their implementation when it goes to 
Draft Standard--which, by definition, incorporates experience with 
interoperability problems.

Because MIME-encapsulation only works some of the time, and a CHARSET property
helps with that complimentary set.  


I cannot recall any MUA that transcodes attachments (I would be interested to
hear of an example), so I don't think that suggesting such transcoding is the
duty of the MUA is a useful resolution to this issue, nor do I think that the
potential problems with naive transcoding rule out a CHARSET property.

Some comments on other emails I recieved today:

The majority of non-EBCDIC character sets implement the invariant portions of
ISO 646, so the property would provide usable information in those cases.

Windows NT (and it heirs and assigns) are natively Unicode, but Unicode is not
commonly used as the storage format for text documents (in the US, at least);
the only UNICODE-capable editors than come to mind are TextPad and Emacs.

Until someone proposes and this WG agrees to a new iCalendar
transfer protocol. I do not know of any proposed inter vendor
issues with charset and iCalendar, iTIP, iMIP, or CAP. So
far all of the issues presented are implementation issues and
they are not protocol and transfer of information issues.

And makes some implementations objects in some charsets break.

This WG is concerted with transporting iCalendar objects between vendors
as an interoperability protocol. Why should we care if you can hand
edit an object or not? Copy/Paste and object or not?

I can not find anywhere in the charter or in 2445 that states only certain 
transfer protocols are allowed. To me, this means that the iCalendar object 
is encapsulated well enough that it does not matter what transfer protocol is 
used. Many statements in the rfc and charter back this up.

I care about how people will use ICalendar and I would like to see it used in 
many flexible ways. I believe the spirit of ICalendar is to have an 
encapsulated format you can send with any transport mechanism you like - even 
if that transport mechanism is something as simple as the clipboard.

It seems to me the original authors of the spec (perhaps we could ask them) 
went through enormous pain in order to provide this flexibility and succeeded 
in every way except for the charset issue. As Chris mentioned, there is even 
a quote from 2445:

Formal Definition: The character sets supported by this revision of
   iCalendar are UTF-8 and US ASCII thereof. The applicability to other
   character sets is for future work. 

This leads me to believe that we are doing this future work right now, and can 
complete the spec as it was intended to work.

Comments welcome as always.

The MUA I use does this as well, and it isn't based on metamail. (I've been
considering giving it access to content-disposition parameters as well.) And
the EMS callout interface in Eudora provides access to both content-type and
content-disposition parameters.

It is also worth pointing out that the mailcap format metamail and others use
that includes this ability to access content-type parameters is specified
in RFC 1343.

More than one, actually. FWIW.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Calendaring and Scheduling Working Group of the IETF.

	Title		: Calendar Access Protocol (CAP)
	Author(s)	: D. Royer et al.
	Filename	: draft-ietf-calsch-cap-10.txt
	Pages		: 148
	Date		: 2003-3-5
	
The Calendar Access Protocol (CAP) is an Internet protocol described
in this memo that permits a Calendar User (CU) to utilize a Calendar
User Agent (CUA) to access an [iCAL] based Calendar Store (CS).
The CAP definition is based on requirements identified by the
Internet Engineering Task Force (IETF) Calendaring and Scheduling
(CALSCH) Working Group.  More information about the IETF CALSCH
Working Group activities can be found on the IMC web site at http://
www.imc.org/ietf-calendar and at the IETF web site at http://
www.ietf.org/html.charters/calsch-charter.html [1].  Refer to the
references within this memo for further information on how to access
these various documents.

A URL for this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-ietf-calsch-cap-10.txt

To remove yourself from the IETF Announcement list, send a message to 
ietf-announce-request with the word unsubscribe in the body of the message.

Internet-Drafts are also available by anonymous FTP. Login with the username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then
	"get draft-ietf-calsch-cap-10.txt".

A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html 
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt


Internet-Drafts can also be obtained by e-mail.

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-ietf-calsch-cap-10.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.

OK, I'm dropping this line of argument; I was grossly ignorant.

Well, obviously, somebody cared when 2445 was written.  From the Abstract:

   addition, the content type is useful as an object for interactions

Clipboards tend to be typed, but I'm not aware of any that uses MIME 
headers.  Mac doesn't; X doesn't; I'm pretty sure Windows doesn't (not 
surprising, since all of these predate MIME--RFC-1341, 1992).

Admittedly, it doesn't actually seem to be covered in the WG's charter.

Hear, hear.  In fact, given the tarpit that awaits us if people fall 
into the trap of placing non-UTF-8 iCalendar objects into non-MIME 
environments (as they are starting to do), I'd say it might be important 
enough to split our attention and work on it alongside CAP.

I'm working on validating my 2445 parser (written in Python); can anyone point
me at a test suite?  I'm also interested in any data people can share about
differences between implementations; I've found some pages on the web about
Outlook compatibility, but that's about all.

Thanks -

The original spec (RFC2445) required that the fidelity of the iCalendar 
object be maintained even after all of the MIME information was stripped 
off. The interpretation was that if something (e.g., Clipboard) took the 
object and repackaged and retransmitted it, it would remain unchanged 
between (inclusive)

BEGIN:VCALENDAR
...
END:VCALENDAR

So even though the spec was for MIME-encoded transmission of calendar 
objects, the MIME/message header was not to contain anything necessary to 
interpret the object. Unless and until changed, I would take that to mean 
that after the message is decoded, it would be back to UTF-8 or US ASCII. 
The spec was for "over-the-wire" transmission but the iCalendar object 
itself contained the specified parameter tags and values necessary to 
recreate the event by the receiving application.

I would suggest:

4 iCalendar Object Specification
   The following sections define the details of a Calendaring and
   Scheduling Core Object Specification. This information is intended to
   be an integral part of the MIME content type registration. In
   addition, this information can be used independent of such content
   registration. ******** In particular, this memo has direct 
applicability for
   use as a calendaring and scheduling exchange format in file-, memory-
   or network-based transport mechanisms. ******** We wouldn't maintain 
the MIME wrapper for file-, memory, or network-based transports AND "can 
be used independent of such content" --RP

On the CHARSET issue... Doesn't this suggest the use of UTF-8 for the 
objects?
4.1 Content Lines
...
NON-US-ASCII       = %x80-F8
     ; Use restricted by charset parameter
     ; on outer MIME object (UTF-8 preferred)
... ********** Non-US-ASCII was specifically restricted to OUTER MIME 
objects only (UTF-8 preferred) -- RP

4.1.4 Character Set

   There is not a property parameter to declare the character set used
   in a property value. The default character set for an iCalendar
   object is UTF-8 as defined in [RFC 2279].

   The "charset" Content-Type parameter can be used in MIME transports
   to specify any other IANA registered character set.
********** the CHARSET can be used in MIME transports -- not iCalendar 
object -- RP

I would have to look at the rest but these are a couple of quick 
references.
Regards,
Ralph Patterson

I think the issues here is that none of the RFCs mandate how the
data is to be stored by the application. They talk about interoperability,
not implementation.

So it is working as specified and as you sited in your reply. We have
defined how to transport 2445 objects using e-mail and now CAP. And
the 2445 objects can be used in small devices and it will never
matter to any RFC how the small devices store the 2445 objects.
When small devices export a 2445 object they will take what ever
their internal format and charset, then send e-mail or use CAP.
If the small device uses another transport then it is ether going
to be some future proposed protocol or a proprietary protocol.
No one has proposed any other transport or protocol so I SEE
that as covering all of the issues.

Sorry for not answering before, I'm really busy at the moment and I
can't give the topics we are discussing the attention the deserve.
However, I think I should at least answer this one.

In 10.8 we have this text:

 The data in each result contains an iCalendar object composed of all
 the selected components enclosed in a "VREPLY" component.


First of all, I'm not sure this text is ok because SEARCH can select
"things" which are not components - and this sentence should be changed
to reflect that.

Apart from this, and assuming a query like SELECT * FROM VEVENT WHERE ....,
am I right in assuming I'll get back all selected VEVENT inside one VREPLY
(inside one VCALENDAR per target/method, as usual)? That is

BEGIN:VCALENDAR
BEGIN:VREPLY
BEGIN:VEVENT
...
END:VEVENT
BEGIN:VEVENT
...
END:VEVENT
END:VREPLY
END:VCALENDAR

and not:

BEGIN:VCALENDAR
BEGIN:VREPLY
BEGIN:VEVENT
...
END:VEVENT
END:VREPLY
BEGIN:VREPLY
BEGIN:VEVENT
...
END:VEVENT
END:VREPLY
END:VCALENDAR


I was just wondering whether this is intentional, given that this is
different from all commands (except GENERATE-UID).

Above all, this doesn't sound very useful when used with queries like
SELECT UID,ATTENDEE FROM VEVENT WHERE ...

If I'm just misunderstanding, then I think that sentence must be
clarified.

Bye,
	Andrea

Correct and thanks - I changed the text to be:

      The data in each result set contains one or more iCalendar components
      composed of all the selected results enclosed in a single "VREPLY"
      component per "QUERY".

      Only "REQUEST-STATUS" property and the properties mentioned in the
      "SELECT" clause of the QUERY are included in the components.
      Each "VCALENDAR" component is tagged with the "TARGET" property.

I updated the reply text of the example that matched the text you
quoted above from CAP to be:

      Here the request was successful, however one of the "VEVENT" components
      contents were not accessible (4.1).

I was reading another WG document this weekend and noticed that we
did not include a description of the sort order when two or
more results were a partial match of each other.

I would like to add to cap:

	When determining which object to return first on sorted results
         when two or more results partially match each other, the shorter
         match will be returned first. If the following:

		SELECT SUMMARY FROM VEVENT WHERE ...

	returned two matches:

		SUMMARY:ABC
		SUMMARY:ABCD

         The "VEVENT" component that had the "SUMMARY" property value of "ABC"
         must be returned before the longer "ABCD" result.

I really do not care if the longer or shorter one is returned
first - I just picked one. Any objections?

I'm not sure what this means.  The word "partial" doesn't appear in 
draft 10; are you talking about queries using LIKE? Why would the sort 
order depend on the nature of the query? The draft defines the sort 
order as depending on the order in which the columns are listed; I 
assume that means listed in the cap-cols production, which makes it 
independent of the query.

Why wouldn't you just use the ordinary string sort for the locale, as 
specified in 6.1.1.6?

What are partial matches?

[attempting to send this again,
 as it seemed to have not gotten to the list last time.]


recommendations for java beep packages (for use with cap)?
looked some or a lot at each of following.

simplebeep:
	does not look like any recent activity on this project
	quite a few installation prerequisites
beep4j:
	does not look like any recent activity on this project
permabeep:
	seems to have no sasl profiles
	but does include a mime library
	  (assumably could be used independent of the beep support)
beepcore:
	includes sasl anonymous and otp (whatever exactly those are)
	may be simpler to use than permabeep, but not as flexible?
	seems to require 1.4+ (java.util.logging).
are there better choices?

beepcore seems the most likely.


thanks in advance.

below are some suggested changes for section 1. of the cap-10 draft.
most of it is very minor (as minor as an extra space...).
I believe there is nothing reguarding the actual function of the spec.

reading it properly depends on mail not reformatting the text and
text being displayed in a fixed-width font,
so I am not sure how well it will come across.


the numbers in [] at the beginning of each are the page and line numbers.

I think the markup is obvious, but:
	X under text indicates it should be deleted
	^ under text indicates an insertion point (insert before)
          followed by the new text
	- under text indicates it should be changed (w/a specific substitution)
	  followed by the new text or a comment/question
	* under text indicates what is specifically being commented on
	  followed by a comment in ()

   This document specifies how a Calendar CUA interacts with a CS to
                                 XXXXXXXXX
----------------------------------------
[6;305]

   The definition of new components, properties, parameter's, and value
                                                          X
   types are broken into two parts.  The first part summarizes and
   defined the new objects.  The second part provides the detail and any
         -s
   ABNF for those objects.
----------------------------------------
[7;362]

   Within a query, the different parts are referred to as a "clause" and
   its value as "clause value" and the clause name will be in uppercase
   enclosed in quotes.  Example, The "SELECT" clause or if the "SELECT"
                        ***********************************************
   clause value contains ...
   *************************
(
this sentence seems inconsistant with the other like sentences and
does not seem constructed properly...
)
----------------------------------------
[9;459]

   Calendar Access Rights (VCAR) -  The mechanism for specifying the CAP
      operations ("PERMISSION") that a particular calendar user ("UPN")
      is granted or denied permission to perform on a given calendar
      object ("SCOPE").  The calendar access rights are specified with a
      "VCAR" component.  (Section 9.3.
                                     ^)
----------------------------------------
[9;482]

   Properties -  An attribute of a particular component.  Some
      properties are applicable to  different types of components.  For
                                   X
      example, the "DTSTART" property is applicable to the "VEVENT",
      "VTODO", and "VJOURNAL" components.  Other components are
                                                 ----------properties
      applicable only to an individual type of calendar component.  For
      example, the "TZURL" property may only be applicable to the
                                    ---is
      "VTIMEZONE" components.
----------------------------------------
[10;538]

   CAP Session -  An open communication channel between a CUA and a CS.
      If the CAP session is authenticated, the CU is "authenticated" and
                                          ^ then
      it is an "authenticated CAP session".

   Contained Component / Contained Properties -  A component or property
                                          ---y
      that is contained inside of another component.  A "VALARM"
      component for example may be contained inside of a "VEVENT"
      component.  And a "TRIGGER" property could be a contained property
      of a "VALARM" component.
----------------------------------------
[11;593]

   Owner -  One or more CUs or UGs that are listed in the "OWNER"
      property in a calendar.  There can be more than one owner.  The "
                                                                *******

I big time object.  This just makes the CS have to cache up ALL matching 
objects/values to return before it can return ANY so that it can sort them 
based on some implyed sort order (the order of the SELECT).  This makes 
bounded latency even worse!

The CS should NOT have to cache ALL results before it can send back any 
results at all.  The CS should be able to send back data as soon as it can 
thus allowing the data to flow back to the requestor as its available.  My 
users are looking for better performance, not worse.

True.  We've been over this before, though I don't remember the 
discussion well enough to know why we settled on sorting.

My take is that sorting is like any other CPU-intensive operation: if 
you want the system to scale, you need to push it to the edges.

I just noticed this e-mail on the IETF-general list.


-------- Original Message --------
Subject: I-D ACTION:draft-pessi-ical-isip-01.txt
Date: Tue, 11 Mar 2003 06:46:22 -0500
From: Internet-Drafts@ietf.org
Reply-To: Internet-Drafts@ietf.org
To: IETF-Announce: ;

A New Internet-Draft is available from the on-line Internet-Drafts directories.


	Title		: iCalendar SIP-Based Interoperability Protocol
	Author(s)	: P. Pessi, M. Mela
	Filename	: draft-pessi-ical-isip-01.txt
	Pages		: 13
	Date		: 2003-3-10
	
This document, proposes a binding from the abstract iCalendar
Transport-independent Interoperability Protocol (iTIP) using Session
Initiation Protocol (SIP) as transport and SIP/SIPS URIs as
addresses. This document proposes using the iTIP objects as a MIME
payload format with SIP. iTIP is an abstract transport protocol for
exchanging calendaring information between calendar systems using the
iCalendar, Internet Calendaring and Scheduling Core Object
Specification defined by RFC 2445. SIP is a application-layer
signaling protocol for creating, modifying, and terminating
multimedia sessions, retrieving user presence and sending instant
messages.

A URL for this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-pessi-ical-isip-01.txt

To remove yourself from the IETF Announcement list, send a message to
ietf-announce-request with the word unsubscribe in the body of the message.

Internet-Drafts are also available by anonymous FTP. Login with the username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then
	"get draft-pessi-ical-isip-01.txt".

A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt


Internet-Drafts can also be obtained by e-mail.

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-pessi-ical-isip-01.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.

What do you do with the other items that must be sorted that is
any different?

just so that I'm sure I understand your POV: are you objecting to
Doug's proposal or are you objecting to sorting in general? Sorting
is still in the draft and I don't recall anybody objecting to it in
recent times at least (read, last year).

My opinion is that sorting is irrelevant and badly specified anyway [1];
I agree with John that sorting should be done at the client.

Bye,
	Andrea

[1] the draft says the results are sorted depending on the order in which
columns appear in the query. This means the rather common SELECT * ... has
no specified order.

Sorting is in the latest draft as you noted.  However it was was added to 
Draft 08 (so sometime between March 2002 and June 2002).  It was (is!?) an 
issue before and I honestly do not recall reaching a concensus on it nor 
do I have cycles to research it. 

It was originally added to Draft 08 as just:

6.1.1.6 Ordering of Results

   Sorting will take place in the order the columns are supplied in the
   QUERY command.

and is now covered in 2 sections in Draft 10:

6.1.1.6.  Ordering of Results
    Sorting will take place in the order the columns are supplied in the 
QUERY command. The CS MUST sort at least the first column. The CS MAY sort 
additional columns. 

and

6.1.1.7.  Date sorting order

    If EXPAND=FALSE sorting will be by the "DTSTART" property value 
ascending as if it were in UTC. 
     If EXPAND=TRUE sorting will be by the "RECURRENCE-ID" property value 
ascending as if it were in UTC. 

I have an aversion to having the sorting requirement as stated as it 
precludes ANY ablity to send results back to the requestor as they are 
found.

I think that having the CS "sort all results alphabetically (or reverse) 
based on SUMMARY and then DESCRIPTION [and then by LOCATION...]" is not 
necessarily all that useful.  Sorting based on the order of the SELECT 
clause is something that the UI really wants, NOT that CAP itself needs 
IMHO.  Sorting is more of a rendering concern than a protocol concern 
really.

> My opinion is that sorting is irrelevant and badly specified anyway [1];

Make that 3 votes for sorting in the client rather than in the CS.  (If my 
MUA can insertion sort mail that arrives out of order in my Inbox, why 
cant my CUA?)

could the sort be specified in the query
(as in ORDER BY ... ASCENDING/DESCENDING)?
sorting would then only be done if and as desired.
or was that already discussed and rejected?

below are some suggested changes to and questions about
section 2. of the cap-10 draft.
a lot of it is minor text fixes or possible abnf problems.
but I also have some questions about some of the abnf.
I believe there is nothing reguarding the actual function of the spec.


(same format as my previous msg about section 1.).

Last night that kinda felt odd so I did another check this AM and found 
that it was actually added into Draft 03 which was Dec 2000.  I have to 
blame user error in trusting MSIE to search the archives on Dougs site for 
this (after all searching for "sort" should find any hits).  Time to use 
Opera again... 

In briefly going back to the archives I see that we had no real meaty 
discussion on adding sorting so some of the more heated discussions must 
have been at an IETF meeting.  The effort appears to have been triggered 
by Mark Pattersons discussion of ordering of results but in the context of 
the CAP requirements doc, not acutally in CAP discussions.

In any case since there are previously expressed concerns by both John 
Strack (ie: locale) and Andrea (ie: The '*') case as well as my own 
dealing with the impact to bounded latency I think some cycles need to be 
put into a better solution or we should remove the implicit sorting 
entirely.  I for one though have far fewer cycles to spare these days on 
CAP so I cannot offer any text now.  I can suggest we take the KISS 
approach and simplify the design for CAP 1.0 and remove the sorting 
entirely.  After all it was Doug who originally (1999) wanted to take this 
approach if I recall correctly...

So you are saying that just because you were busy (or for what ever
reason) and did not wish to participate in that discussion that it
does not count (as meaty)? Sorry - it was discussed and you elected
not to particapte for what ever reason. It is time to close CAP
and ship it.

I am confused - you site Mark Pattersons discussion of ordering (which
IS on the list) and yet declare there was not a CAP discussion? Explain
what a discussion is if that is not it?

It was in CAP-00, draft-ietf-calsch-cap-00.txt dated August 5, 1999 :


   orderby         = <any valid SQL string that goes into a ORDERBY
                    clause>

As some did not want SQL, this was changed into explicit sorting
as the debate went forward. It has been in CAP for years.

I've been watching the exchange of emails and many of them are bringing up
old topics.  At this point, I'd like to propose a last call on CAP.  Guys,
we need to get something out there for vendors to try to implement.  It's
only at that point that we really find out what does or does not work.  We
are NEVER going to have a perfect solution.  At this point, I'll take a
"mediocre" solution - because at least it's something.  So, that being
said, I am formally proposing a last call on CAP.  All those violently
opposed please respond to the list with specific reasons why you are
opposed.  Also, respond to the list if you are in favor of a last call.  We
can't do HMMMMs on the list - but we can do electronic "thumbs up".  Those
will work as well.  We'll talk more about this at the IETF meeting in SFO.
If you can not be there, try using the Jabber method to participate.

I am opposed to including sorting.  Server-side sorting:

    * Will increase CPU and buffering requirements on the server, which
      will hurt scalability.
    * Will increase latency.
    * Will not be of substantial benefit to clients.  Server-side
      sorting has been advocated as being helpful for
      resource-constrained clients such as PDAs; but, realistically, a
      client that cannot afford to sort a set of events is going to have
      difficulty displaying that set.
          o There is one narrow set of clients which are an exception
            here: Web-based CUAs.  Some simple UIs can be rendered more
            efficiently if the application can stream data down from the
            CS, transform each event it sees into HTML, and then discard
            the event without buffering; if the stream from the CS is
            not ordered, then it must be buffered and sorted.
          o However, this is less of a constraint than it seems.
             Normally, in a large-scale Web-based application, there are
            many Web servers and few database servers (or, in this case,
            few CAP servers); if the sorting has to be done, it should
            be done in the Web servers, to spread out the cost of
            sorting.  (Scalability again: it's normally cheaper to buy
            10 boxes with, say, 2 GIPS and 2G RAM apiece than to buy 1
            box with 10 GIPS and 10G RAM.)
    * Will actually increase costs for some constrained clients, such as
      wireless devices where connect time is charged by the minute.
       Increased latency means increased connect time, after all.

I realize that we've gone over this before; but, if Doug's dates are 
correct, then this is stuff I learned after we discussed it last, while 
building eCal's second-generation product.

ONe of the best ways I know to shake out bugs and fruit from a tree is to
ask for a Last call.  And, for the first time in a long time, we seem to
have concensus on something.  Be still my heart.  I am now hearing 4 people
say removing sorting to the client and out of the CS is a good thing.
Sorry, Doug, but that does indeed stand as concensus and not even rough.
Now, that being said, is this hard to do and does it break something else.
If so, maybe we can get some help from those who are arguing to have it
removed.  5 pair of eyes looking at the draft to remove this would really
help  a lot. 8-)

I vote against this. 

I've read the archives, I'm mainly a lurker with desires to build an
Open Source CAP Server (http://www.sf.net/projects/jical)

I would have thought ordering was a natural requirement of a server vs a
client. Surely your data store can make these things easier via indexes
etc. The comparison to an Inbox doesn't stack up. From reading the spec
- CAP Servers are more like a specialised RDBMS. Imagine if your RDBMS
did not support ORDER BY? An alternative would be to add the ORDERBY to
capabilities so that the client can query and see if the server can/will
handle ORDERBY.

As do I.

Would the others agree to a SORT capability? Where the default is "NONE"?
Something like:

	SORT:none         -> Any random order.
	SORT:SORT-1       -> As currently in CAP.

This would cause less changes and debate than removing SORT completely
and if we agreed then it is less change to CAP and allow us to
ship CAP sooner?

Comments?

Thanks

I vote against this.

I've read the archives, I'm mainly a lurker with desires to build an
Open Source CAP Server (http://www.sf.net/projects/jical)

I would have thought ordering was a natural requirement of a server vs a
client. Surely your data store can make these things easier via indexes
etc. The comparison to an Inbox doesn't stack up. From reading the spec
- CAP Servers are more like a specialised RDBMS. Imagine if your RDBMS
did not support ORDER BY? An alternative would be to add the ORDERBY to
capabilities so that the client can query and see if the server can/will
handle ORDERBY.

Not really, no.  Anything that can be done with equal ease on the server 
or on the client should be done on the client, because everything is 
more expensive on the server, where it has to be done many more times.

Indices can make sorting more efficient; but it gets really expensive to 
maintain indices on every column, which is basically what would have to 
be done to meet this requirement.

That wouldn't be much of a problem, actually; I'd just sort in the 
client-side code.  I use SQL pretty regularly these days, and I know of 
only two advantages for having ORDER BY in the language: (a) it's 
convenient for people writing queries by hand; (b) indices.  (A) is not 
something we should be worrying about; (b) is expensive.

(The big difference between indices for CAP and indices for a SQL 
database is that the schema of SQL databases tends to get customized to 
match the application; you can apply the indices that you think you're 
going to need.  A CS can't do that, because it has to work with any CUA.)

Not a good idea.  The more optional features we have in the protocol, 
the harder it is for a client author to make sure their client can 
interoperate with every server.

I mean, come on, guys.  We're talking about *sorting* here.  It's 
potentially CPU-intensive if you've got a huge dataset, but it's hardly 
a big deal to implement.  Any sensible language will have a generic 
sorting feature in its standard library; even C has qsort().  If you're 
on a constrained device, you can put a limit on how many items you're 
going to sort, which will probably be pretty close to the number of 
items you can reasonably display; if you can't sort, you put up an error 
message or something.  The tradeoffs to be made here depend on the UI, 
which means the decision should be made in the CUA.  If the protocol 
specifies that the server has to sort, then it has no idea what the 
tradeoffs are.

Not quite. 

Ive been one of the most consistanly active folks in the WG since it was a 
BOF.  There have been times when I was less than immediately responsive to 
postings (work pays the bills so it takes priority to the WG) but Ive 
always tried to keep up on the threads.  I cannot think of anyone else 
whose had my record of consistant engagedment in this WG so dont try to 
make it sound like I was not engaged.  Unless it was around the end game 
time of Notes R6 (~May - Sep 02) I've been involved in the discussion.

I did a FT search of the archives for the word "sort" and there was NOT a 
big discussion of sorting as you would suggest.  We did have some 
discussions on it and there was NOT the concensus you claim there is.  In 
fact so far I hear only a concensus that it should NOT be in CAP.

CAP has been drawn out over several years but I do not think we should 
just push it out the door because its taken so long.  I have listed 
several issues in the past that have NOT been addressed and we still have 
some (ie: Stored VQUERYs, sorting, a LOGOUT command, signatures, multipart 
MIME, etc) that need to be addressed before we can attempt a Last Call. 
There are also the blank areas related to BEEP that have not yet been 
filled in for anyone to review.  So I do not think CAP is ready for a Last 
Call yet.

Once we "ship" CAP 1.0 we have to live with the warts it has if we (or 
some future effort) tries to fix up and extend CAP to include features too 
tough to get into CAP 1.0.  I think we need to make sure the bigger warts 
are gone before we try to foist it off on folks and then sell products 
based on it.  Otherwise CAP becomes a wasted protocol since its too buggy 
or kludgy to implement.

Cant help your confusion any more than say go reread the archives.  A FT 
search of the archives all the way back to the BOF days reveals 374 
documents that contain the word 'sort'.  This includes:

11 messages under this subject (excluding any traffic after my last msg)
8 messages under the CHARSET discussion recently
270+ messages sent during iCalendar/iTIP/iMIP (and cruft) development 
discussions.  I kinda got lost after 280ish messages so Ill call it 270+
80+ messages unrelated to actual sorting.  Stuff like "intend to answer 
the sort of questions" or "I sort of was thinking...". or "going to work 
sort of " or  "taxes out it's just sort " from Johns .sig.

This rough check of 'sort' is ~369 messages.  Deduct that from the 374 
found and that leaves ~5 messages.  That must have been a very meaty and 
engaging discussion and concensus building.  Maybe it was done under the 
term "ORDERBY" and noone ever used the phrase "sort" (I guess its 
possible...).

FYI: The Mark P. thread was ~29-Nov-2000 under the Subject "CAP 
requirements draft resubmitted".  It only had ~8 msgs in that thread.  I 
would not call that "meaty" either.  Perhaps you do, I don't know.

In any case so far I hear 4 votes against the sorting and 1 for it.  The 
300+ rest are abstentions.  To me that sounds like rough concensus to 
remove it.

But then every client that cared about sorting would need to be able to
do sorting itself in case it was talking to a SORT:none server. And if
it has to have the code to do it sometimes, then why not do it all the
time?

Thats probably because we never reached concensus on some of them before 
moving on. 

I havent seen an updated CAP issues list in probably a year so its hard to 
tell if we've discussed them all and resolved them.  The last reference to 
it I can find (not an actual WG posting) was by George B. back on 
30-Jan-2002 under the heading "Updated CAP To Do and Issues List".  Until 
we can say we've at least covered THOSE issues I think we cannot go to 
Last Call.

Id prefer a solution that while not perfect does not make fixing things in 
the future so Bisentine or impractical as to be nearly impossible.  No 
protocol has been "perfect" out of the shoot (POP3 is 3rd revision, 
IMAP4rev1 is 4th revision, etc) but before we can push the baby out the 
door we need to make sure we dont have just danging holes in it or cruft 
that is not relevant / useful anymore.

We have unresolved issues that have not been declared as resolved:

1: Stored queries (no demonstrated usefulness for PDAs or 'fat' clients 
alike given our query language).
2: Sorting (see John's postings as far back as 2000 even).
3: The BEEP examples and registration profiles (ie: Section 12.1. BEEP 
Profile Registration  of the Draft 10-17Feb2003) is not even filled in 
_let alone_ discussed at all in the WG.  It is still "TBD" in the latest 
draft.
4: We have not made sure that any CAP issues that we overlooked have been 
addressed.  Examples of this include those:
        A: Deletion vs 'marking for deletion".  Its totally unclear what 
the disction is, what benefit 'marked for deletion" is and if it possible 
to undelete, etc.
        B: Multipart MIME support.  There is no text or examples dealing 
with how multipart MIME should be properly dealt with in CAP.  I had hoped 
we would have learned from iTIP interop testing but so far no...
        C: CAP preservation of IANA or X- properties/parameters, etc. 
Unlike iTIP where some properties are not guaranteed to be preserved by 
different implementations, CAP is how a CUA accesses a store so it SHOULD 
preserve everything.  This is NOT clearly defined and proscribed for any 
CS.
5: We have made

The last posted CAP issues list was dated 03/15/2001 12:45:39 PM by George 
B.  There is an online one at the calsch web site that may or may not be 
insyc with that list and it has 25 unresolved issues on it with various 
assignments.  Im sure some have to have been done by now but I say we 
update that list to make sure we cover them all.

There are 'known issues' that we have decided to ignore for CAP 1.0 but 
they are NOT listed in any "Known Issues" section of CAP and they should 
be.  It is MUCH better for us to say "Here are the areas we know are 
touchy and have decided to punt on.  Implementations cover them at their 
own risk....".  Better to acknowledge all the big cow patties than to 
pretend they are not there!

I wont be in SFO and cannot make any promises about eAttendance.  Last 
time I tired it did not even limp along.

Another issue from WAAAY back was the proliferation of top level Response 
Codes in CAP.  From Section 10.11. Response Codes:

    Code              Description
    --------------------------------------------------------------
    2.0               Success. The parameters vary with the
                      operation and are specified.

    2.0.3             In response to the client issuing an
                      "abort" reply, this reply code indicates
                      that any command currently underway was
                      successfully aborted.

    3.1.4             Capability not supported.

    4.1               Calendar store access denied.

    6.1               Container not found.

    6.2               Attempt to create or modify an object
                      such that it would overlap another object
                      in either of the following two circumstances:

                      (a) One of the objects has a TRANSP
                      property set to OPAQUE-NOCONFLICT or
                      TRANSPARENT-NOCONFLICT.

                      (b) The calendar's ALLOW-CONFLICT
                      property is set to FALSE.

    6.3               Bad args.

    6.4               Permission denied - VCAR restriction.
                      A VCAR exists and the CS will not perform
                      the operation.

    7.0               A timeout has occurred. The server was
                      unable to complete the operation in the
                      requested time.

    8.0               A failure has occurred in the CS
                      that prevents the operation from
                      succeeding.

    8.1               A query was performed and the query is
                      too complex for the CS. The operation
                      was not performed.

    8.2               Used to signal that an iCalendar object has
                      exceeded the server's size limit

    8.3               A DATETIME value was too far in the future
                      represented on this Calendar.

    8.4               A DATETIME value was too far in the past
                      to be represented on this Calendar.

    8.5               An attempt was made to create a new
                      object but the unique UID specified is
                      already in use.

    9.0               An unrecognized command was received.
                      Or an unsupported command was received.


    10.4              The operation has not been performed
                      because it would cause the resources
                      (memory, disk, CPU, etc) to exceed the
                      allocated quota.

This adds 6, count 'em 6, new top level classes above and beyond the 4 
defined in RFC 2445:

     |==============+===============================================|
     | Short Return | Longer Return Status Description              |
     | Status Code  |                                               |
     |==============+===============================================|
     |    1.xx      | Preliminary success. This class of status     |
     |              | of status code indicates that the request has |
     |              | request has been initially processed but that |
     |              | completion is pending.                        |
     |==============+===============================================|
     |    2.xx      | Successful. This class of status code         |
     |              | indicates that the request was completed      |
     |              | successfuly. However, the exact status code   |
     |              | can indicate that a fallback has been taken.  |
     |==============+===============================================|
     |    3.xx      | Client Error. This class of status code       |
     |              | indicates that the request was not successful.|
     |              | The error is the result of either a syntax or |
     |              | a semantic error in the client formatted      |
     |              | request. Request should not be retried until  |
     |              | the condition in the request is corrected.    |
     |==============+===============================================|
     |    4.xx      | Scheduling Error. This class of status code   |
     |              | indicates that the request was not successful.|
     |              | Some sort of error occurred within the        |
     |              | calendaring and scheduling service, not       |
     |              | directly related to the request itself.       |
     |==============+===============================================|

Nowhere can I find a description of these new top level classes and what 
they mean. (What the hell is a class 9x. response code good food for and 
how does it compare with a class 10.x or 8.x???). 

I have previously noted that there is NO 5.x description or class but that 
has somehow been overlooked.  I have also noted that we have a 10.4 but no 
10.0, 10.1, 10.2 or 10.3.  Basically we need to take a cleanup pass over 
the new status codes to make sure we organzie them properly and cleanly.

We should clearly define these new top level classes (ala RFC 2445) and 
possibly consolidate them down so we have a deeper response tree than a 
flatter one.  After all that is why we defined the value to be 
hierarchical in the first place in iCalendar.

I have seen the following link posted as a new draft.  http://www.ietf.org/internet-drafts/draft-pessi-calsch-isip-00.txt.  Does anyone know about this?  The draft says it's part of our working 
group - but I sure don't know about it.  It really should not say it is 
associated with our group if it's never been discussed here.  It can have 
a different title and be ok.  But it should not say CALSCH WG if it's 
never been discussed in the group.  So I'm checking here to see if anyone 
is aware of what this is.

Hi Pekka.  The document references that it is a CALSCH working group 
document.  We've never seen it discussed here nor is it a part of our 
charter.  Can you fill us in a little on what this is?  I see why you 
think it is part of our WG - however, we sort of have to get permission 
from our Area Directors to add items to our charter.

>I just noticed this e-mail on the IETF-general list.

                 I first received an automatic rejection reply, so I 
thought I'll
                 have to send it again after cutoff period. Christmas 
seems to
                 come twice this year.

                 The document now recommends using the "text/calendar" 
format,
                 and the examples have been converted to the iCal.

                 There are a few open issues, most important I think is 

                 *what to do when a recipient cannot be reached 
immediately?*

                 If delivery falls back to some other system than SIP, 
e.g.,
                 e-mail, what kind of addressing could be used? How a 
recipient
                 can process and an iSIP message if it is received via 
non-SIP
                 means?

                 There is no applicability statement in the draft. Our 
main
                 purpose here is to have off-line invitations to SIP 
conferences
                 with standard format describing attendees and resources 
of SIP
                 conferences.

                 Unfortunately I've had no opportunity to dig in iRIP, so 
I
                 really can't say for sure what makes iSIP radically 
different
                 from iRIP. In my opinion, iSIP is just an alternative 
transport
                 for iTIP with its own addresses. SIP is an existing 
transport,
                 which propably will live and prosper on its own. iSIP is 
useful
                 even if there is no real calendaring system available by 
SIP
                 user-agents. It also helps to integrate the calendar and
                 telephone applications in future mobile phones and PDAs.

The rule is only for things named "draft-ietf-calsch-", isn't it?  It's 
unusual to see an individual submission named for a WG when it hasn't 
been discussed there, but it isn't forbidden.  And this is related to 
calsch stuff.

(Mind you, I don't like it much; it leaves too much stuff undefined, and 
its abstract seems overambitious.  But that's another story.)

So if you take the REQUEST-STATUS e-mail that I sent one or two
weeks ago and add that into cap - does that solve *this* issue?

It was a proposal on how to merge/fix/update the REQUEST-STATUS
codes. I do not recall that you responded. I got NO negative feedback
and some positive feedback. So I assume the rest of the WG felt
it addressed those issues?

It has been discussed. Did you object to the conclusions? One to Many
or One to One replies? The issues were somewhat hot and you did
participate.

  CAP REQUIREMENTS:

    CAP MUST allow synchronization, meaning at a minimum that the CUA is
    able to find and retrieve new, modified or deleted entries for a
    given time period. The CUA MUST be able to find out which entries
    ...

The discussion that followed ...
You have to be able to tag the entries as deleted, so that a later
synchronization did not think they were new to the CS.

  CAP:

    When synchronizing with multiple CUAs, the marked for delete state
    could be used to inform the synchronization process that an object is
    to be deleted.  How synchronization is done is not specified in this
    memo.

Good point. Are there any objects to saying that CAP MUST store
ALL components, properties, and parameters sent to it by the CUA
subject to VCAR rules?

Thanks for clarifying that John.  The rules are "vague" and elusive until
one does something incorrect - then you find out in a hurry what the rules
really are.  I just wanted to make sure that I covered the bases as the
chair.  Afterall, we all want to have iCalendr used as much as possible -
especially for small footprint devices.

The rule is only for things named "draft-ietf-calsch-", isn't it?  It's
unusual to see an individual submission named for a WG when it hasn't
been discussed there, but it isn't forbidden.  And this is related to
calsch stuff.

(Mind you, I don't like it much; it leaves too much stuff undefined, and
its abstract seems overambitious.  But that's another story.)

I just posted in favor; but then I thought of a clarification: we need 
to permit the CS to ban components for administrative reasons.  For 
example, it seems likely that someone will write a CUA that's equipped 
to spread viruses; once that happens, people will need to be able to 
build CSes that do virus filtering--and that's not something that can be 
expressed in a reasonable VCAR syntax.  ;-)

No it has not!  When I mentioned this months ago the response I got was 
"Later, we want to get the rest of CAP done first.". 

If it was discussed then under what heading and where is the prose?

We were more focused on the issue of ordering responses in CREATE. Falling 
thru the cracks is a very good reason why we need to recheck and reupdate 
the issues list BEFORE we can go to Last Call dont you think?

I found your posting dated 02/22/2003 06:33:16 PM MST under 
"REQUEST-STATUS errors and issues for CAP" and I would have to say no, it 
does not solve the issue.  Here's why:

RFC 2445 does not define a top level 5 class of error but we somehow 
put/left them in RFC 2446.  This is a known issue with 2446 from, oh, 
about 2 or 3 years ago.  This should be fixed when we post errata or an 
update to 2445.  Neither 2446 NOR your posting has any prose on what a top 
level 5.x error code is.  Nothing close to the cited table from 2445 that 
clearly defines them. 

Nor does CAP have anything like it.  Nor does your message address the 
addition of 6 new top level classes in CAP without defining them either! 
Nor does your note address CAPs proliferation of so many near top level 
response codes.

So I guess that would be a definite, No your note does NOT solve _*this*_ 
issue.  If it does, could you point out what I missed so I can reconsider?

We were more involved with the ongoing discussion of ordering of results 
and CREATE and the UTF-8 issues in case you hadn't noticed.  I did not 
respond as it fell out of the active view of things.  In looking now I see 
no negative OR postitive responses.  When issues get squeezed out by more 
active and drawn out threads then silence is not always acceptance; it can 
be just a forgotten posting.

I like this idea.  No need for waffling.  If it failed we let them know. 
If it worked we should also let them know.  After all its only about 18-20 
octets more in the overall data stream. 

However you MUST be careful in how you mandate it so that you do not 
preclude CAP->iTIP fallback in the future (ie: CAP 3.x) since iTIP does 
not mandate REQUEST-STATUS always.

First off, as was noted many many moon ago there is NO 5.x class 
definition in RFC 2445 so:

1: There should be no 5.x error codes in 2446 OR
2: We need to clearly define what the 5.x error codes are used for in 2445 
in the same way that the other codes are defined:

      | Short Return | Longer Return Status Description              |
      | Status Code  |                                               |
      |==============+===============================================|
      |    1.xx      | Preliminary success. This class of status     |
      |              | of status code indicates that the request has |
      |              | request has been initially processed but that |
      |              | completion is pending.                        |
      |==============+===============================================|
      |    2.xx      | Successful. This class of status code         |
      |              | indicates that the request was completed      |
      |              | successfully. However, the exact status code   |

I expect there to be a class 5 error defintion for something like "Server 
Error" or "Service Error" to convey things like "Server internal error" or 
"Server shutting down.  No further commands allowed", etc.  This is 
something we need for CAP but did not need for iTIP when we only focused 
on iMIP usages.  However I have yet to see any kind of prose to this 
effect in CAP (see other threads of late).

Secondly 3.14 is defined in 2446 as:

| 3.14         | Unsupported capability     | Method or action MAY    |
|              |                            | be specified            |

and 5.3 is defined as:

| 5.3          | No scheduling support for  | ATTENDEE property value |
|              | user.                      | MAY be specified.       |

The former means that the METHOD used is unsupported entirely.  The latter 
means that a particular ATTENDEE cannot perform workflow (aka Scheduling). 
 It does not mean they cannot perform Calendaring.  The rest of the 
ATTENDEEs have no problem performing workflow.  The former is scoped to 
the iTIP message entirely.  The latter is scoped to a particular ATTENDEE. 
 Given this I would say that merging 5.3 and 3.14 is NOT the propery 
action.

Im not sure we should collapse them down given the strict definition of a 
class 3 error code.  It is clearly defined as "The error is the result of 
either a syntax or a semantic error in the client formatted request.". The 
inability of an ATTENDEE to perform workflow is NOT this kind of error. In 
looking at the 2445 definitions I think that merging it into 4.x is more 
accurate.  Heres why:

1: The 4.x error code is defined as "Some sort of error occurred within 
the calendaring and scheduling service, not directly related to the 
request itself."  This would easily match the analysis of the intent of 
5.14; a particular user cannot perform "scheduling".
2:The problem described by 5.3 is "No scheduling support for user" and 
error class 4 is defined generally as "Scheduling Error".

Perhaps 5.3 should become 4.1 since we only seem to have defined 4.0 in 
iTIP.

> [NOTE] So I propose that in CAP we specify that code '3.14' means

Why redefine 3.14 for just the ADD method??  It is equally valueable for 
those that do not support COUNTERs or other METHODs (even those TBD by CAP 
or some new effort).  I see no benefit in narrowing 3.14 down to just 
"ADD".  Also, I think this change would redefine the semantics of a clas 3 
error code from being "a semantic error" to being "ADD not supported" and 
thats clearly NOT how 3.x is defined.

Do not touch 3.14 for CAP, its use and meaning is already relatively clear 
and usable.  Its 5.3 we need to focus on instead.

See above first about reclassifying 5.3 as 4.x.

Next, 5.3 says that "scheduling" is not supported by the user".  It does 
NOT say that Calendaring is not supported.  That is, the user can still do 
PIM stuff, just no workflow.  I dont think we should include Calendaring 
as part of the error code semantics.  After all, if the user cannot do 
Calendar OR Scheduling then why the hell would they even use CAP (or would 
they even have a CAP server login)????

> [NOTE] Existing implementations should not be effected as they

Error codes of 3.x and 4.0 are NOT CAP specific and should be supported 
and used by any existing implementation.  As such we cannot just 
arbitrarily redefine the definition of 3.14 (without need!).

Again, if the CUA cannot perform any Calendaring or Scheduling then they 
surely do not use CAP since they essentially could do NOTHING!

This is correct.  The same applys for COUNTERs and DECLINE-COUNTERs 
(although not supporting a DECLINE-COUNTER but supporting COUNTER is kinda 
odd!).  It equally applys to any as yet undefined METHODs that a CUA could 
generate and send.

This is incorrect.  (Imagine that, a mistake in the RFC?!?!)  The VTODO 
prose should mirror that of the VEVENT.  It could be that the change from 
5.3 to 3.14 did not get fully applyed to iTIP prose and that left 5.3 
around (along w/the rest of the 5.x error codes).  After 255+ pages I 
guess noone was coherent enough to notice during Last Call.

In looking at Section 3.6 of iTIP I cannot see ANY prose that indicates 
this.  The restriction tables for each METHOD determine this and I think 
all but PUBLISH have "REQUEST-STATUS 0+".  I cannot recall any 
justification for not having 1+ on at least the REPLY message but perhaps 
that was another oversight.

One thing to consider, if you are going to PUBLISH your calendar then 
REQUEST-STATUS has NO meaning as there is NOT workflow involved.  As such 
mandating it in CAP for PUBLISHes is non-sensical.

Again, either noone saw it or we just thought leaving it out was ok.  Do 
you recall why we took this approach??

Thats because iMIP is just a binding of iTIP and iTIP does the acutal 
content definition.  iMIP just says how to bundle and send an iTIP message 
over email.

BTW: In case we didnt cover this before, in 2446 we have:

| 5.0          | Request MAY supported.     | Method property value   |
|              |                            | MAY be specified.       |

but its gramatically incorrect AND its use is totally vague/indeterminate. 
 Unless we can figure out what 5.0 is intended for and better describe it 
we should probably remove it from iTIP (or reuse it and redefine it in 
CAP)

Doug does not mean partial in the sense of "some matched, some did not". 
He seems to just be taking about substring ordering (at least if you 
follow his examples).  If there is something else then I too missed it.

Sorting is a client side preference/consideration to me. 

Each CUA can sort and resort the results any way the like, kinda like the 
way a good MUA will sort messages by Sender, Subject, Date, etc.  Does my 
mail server have to worry about how I want to sort or resort my data?  No. 
 Does my mail server know my locale settings so that it can sort the 
results accurately?  No.  Does my mail server resort 'new arrivals' 
recieved out of order so that it can render properly in my Inbox.  No, my 
MUA does that too.  The same logic applys to CUAs.

Making the CS sort the results means that the entire set must first be 
gathered THEN sorted THEN returned.  If the CS is going to have to send 
back all the results anyway (assuming I dont ABORT it because its taking 
too long) why not let the CUA do the sorting so that the CS is available 
for other things/users?

Any decent CUA is going to be able to sort / resort data for the CU so why 
not allow it to do the sorting entirely?  That would allow the CS to start 
returning results as soon as it starts to get them rather than having to 
cache them ALL. 

In addition, making a CS store and then sort the results instead of 
returning them immediately will not likely scale well to large user 
counts.  If the set of returned results will be the same no matter if the 
CS sorts them or the CUA sorts them but we get better scalability by 
letting the CUA sort them then what benefit do we get by making a CS do 
the work?

Sorry, the discussion of 1-to-many or 1-to-1 is NOT the sole consideration 
for 12.1 BEEP Profile Registration. 

There is simply NO prose in that section and there has been none given 
since we adopted BEEP last year!  How can we have Last Call on NO PROSE? 
We could NOT have had ANY "hot" WG discussion on NO PROSE, at least not in 
this universe.

I am NOT talking about sync related issues.  Im talking about the overall 
CAP design and how deletions are dealt with in a consistant manner by ALL 
implementations..

Ive mentioned this distintion at least 2 times before and I guess its 
still not clear to some so thats probably a bad sign. 

There is NO prose anywhere describing all kinds of questions around 
deletions such as:

1: The ability to 'unDELETE' entries "marked for deletion".  Is this 
possible / allowed?  (This ability is essentially 'soft deletes' for those 
that recall that topic.)
1.1: Do I actually delete a 'marked for deletion' (MFD) entry from the CS 
by reissuing a DELETE with no MARK parameter or is there some other way to 
actually remove it?
1.2: Does changing the state of the MDF entry effectively undelete it 
(assuming thats possible in CAP)?
1.3: Can an MFD entry be modified in any way (using the right SELECT, 
etc)?

2: Must a CS support marking for deletion (and thus soft deletions) or can 
it just do actual deletions? 
2.1: If a CS does not support marking for deletion then should it treat 
the MARK parameter as optional OR should it fail the DELETE?

3: Is MFD a required feature of a CS or can it just support DELETE but no 
MARK paramter?
3: If soft deletions are NOT mandatory we need some clear prose to 
describe how implementations that do not support it should respond to soft 
delete requests.

4: What are the effects of actually deleting an entry and not just MARKing 
it for deletion? 
4.1: Can a CUA just do this arbitrarily or SHOULD a CUA use MARK all the 
time?
4.2: What is the proper CUA & CS behaviour for dealing with responses to 
either an MFD or actually deleted (irregardless if the CS knows it was 
deleted or if it never existed yet!) entry?
4.3: Should we use DELETE to mean "mark for later deletion" and a _new_ 
(and yet undefined) command like PURGE or EXPUNGE to actually remove 
marked entries?

5: If we cannot unDELETE an entry then why should the CUA distinguish 
between actually deleting it (no MARK parameter) and marking it?  As far 
as the CUA is concerned the entry is gone.  As far as sync goes a sync 
engine just cares if the state is DELETED or not.

6: When does an MFD entry actually get removed from the system?

I am confused - part of my proposal was to renumber the error codes:


	I also propose that we call all 6.x codes CMD or CS codes
	and renumber all 6.x, 7.x, 8.x, 9.x, and 10,x codes to
	be 6.x codes.

  	We may also want to renumber some of these that are not
	used prior to CAP anyway.

So I agree. And please note that I proposed deleting the 5.x codes.
I also think we should/could re-map them into a 'command set' of
errors that are CAP specific.

They were defined, example:


	9.0              An unrecognized command was received.
       	                 Or an unsupported command was received.


And I do not care if it is y.z or 9.x.

Thanks Pat for calling for Last Call so Bruce would read and

Ah.  Substring ordering is definitely specified by any reasonable 
sorting rules; the CS should just stick to the ordering specified by the 
locale (assuming sorting makes it into the RFC, that is :-).

Doug, I did not do a last call so "bruce would respond to an email."  8-)  
I did a last call because we need to get this draft out - sometime in my

I am confused - part of my proposal was to renumber the error codes:


                 I also propose that we call all 6.x codes CMD or CS codes
                 and renumber all 6.x, 7.x, 8.x, 9.x, and 10,x codes to
                 be 6.x codes.

                 We may also want to renumber some of these that are not
                 used prior to CAP anyway.

So I agree. And please note that I proposed deleting the 5.x codes.
I also think we should/could re-map them into a 'command set' of
errors that are CAP specific.

They were defined, example:


                 9.0              An unrecognized command was received.
                                  Or an unsupported command was received.


And I do not care if it is y.z or 9.x.

I know that Outlook does NOT support any kind of multipart MIME types in 
its CUA but its MUA is multipart savy.  As such I had to perform some 
funky MIME bundling to send a richer rendering of iCalendar OR to use 
ATTACHments (which they totally ignore). 

More details can be found in the published interop results (I assume they 
are somewhere to be found on the WG site or in the WG list archives).

Essentially because iMIP did NOT include any prose on multipart MIME 
support or any multipart MIME exmaples, some vendors chose to _only_ 
support text/calendar and thus make interop testing hard/kludgy!

Thats NOT the same as having actual text around how multipart would be 
structured or even an actual multipart example (I know we all hate to put 
them into prose as they become gospel but thats only because we fail to 
provide prose describing exactly how they should be handled/returned).

For example, having some prose around how the CS would construct and 
return a VEVENT with an ALTREP for the DESCRIPTION or an ATTACHment or 
even both.   As a combined example, a CUA would send the following to 
create a VEVENT on the CUs calendar (prefix all lines below with "C: " to 
be consistant w/CAP):

A more complex example could be to replace the last MIME parth with one 
that was of Content-Type: multipart/related and that contained the both 
the text/html AND the image/gif that the HTML refers to!

An alternate way to construct the workflow so that non-CUAs at least 
RENDER it properly is to construct the entry so that the text/calendar is 
part of a multipart/alternative like:

Content-Type: multipart/alternative; boundary=------_alternative_1

        ------_=_alternative_1
        Content-Transfer-Encoding: 7bit
        Content-Type: text/plain; charset="us-ascii"

This latter snippet is really geared towards Scheduling messages rather 
than Calendaring ones but it is still legal and valid to do in both cases.

One unanswered question is how the CUA can tell the CS it only wants the 
text/calendar version / body part  when is uses "SELECT *  FROM VEVENT 
WHERE UID = "7B13A53223F7104C85256CE1005B90CD-Lotus_Notes_Generated"". Or 
will the CUA just get back the text/calendar bits and never see the 
text/html again?  I never found a way to tell the CS "yes send me the 
ALTREPs on DESCRIPTION" or "No, I want just the DESCRIPTION in 7-bit form 
and NO ALTREP this time."

<DIGRESSION>
Also, is there some way for the CUA to say SELECT all properties EXCEPT, 
say, the ATTACHments so that the CUA does not have to itterate over ALL 
possible properties in the SELECT clause and possibly miss or overlook 
some (ie: some extension or other iana-prop)??
</DIGRESSION>

That would probably fall under the "subject to VCAR rules" clause Doug 
suggested.

I for one am in favor of Dougs proposal.

Since when does someone call our VCAR syntax reasonable?  Actually, its 
quite powerful and could easily be used to prevent someone saving 
ATTACHments or other properties and there is nothing preventing a CS from 
rejecting a CREATE or MODIFY command because the contents of the payload 
were infected.  Thats a good reason use for the new 5.x error class 
("Server Error", ie 5.13.2.9: "Command failed due to administrative 
restriction.")

Or perhaps you are proposing we amend the clause to be "subject to VCARs 
or administrative policies"?

Can it check for a virus signature?

Yes, that's all.

In CAP Requirements:

       4.3.1   Deferred Requirements for Operations on a Calendar
	...
    	- How to undelete a calendar.


       4.4.3   Deferred Requirements for Component Management
	...
  	- Undelete and purge deleted calendar entries.

       4.5.5   Deferred Requirements for Search
	...
         - How to fetch all components marked for deletion in a certain
           range. This could include components somehow marked for deletion
           but not yet purged from the CS.


So - out of scope?

Would you be willing to write a draft on how to use Multipart
with iCalendar - perhaps a FYI? It is more than a CAP issue.


I *think* the WG would endorse it!?

Then we do not have to decide for CAP, just decide that we will
support multipart. Right now as you point out that knowledge
is not written down. This would help the those implementing
and help CAP ship sooner.

Sorry, I dont see any such proposal in your "REQUEST-STATUS errors and 
issues for CAP" posting 
(http://www.imc.org/ietf-calendar/mail-archive/msg05916.html).  Did I just 
miss it?

I dont think we need to delete 5.x codes, we merely need to clearly define 
their class ala RFC 2445 did for 1.x thru 4.x.  Then we could start using 
it.  We may want to make 5.x for "Server Errors" akin to the 3.xx class. 
You may want to collapse the 6.x thru 10.x codes down into 4.x since that 
is already defined in 2445 as for "Scheduling Error".

(After all why have 1.x thru 4.x and then 6.x but NO 5.x??)

This defines the code for 9.0, not the overall 9.x class.  An unrecognized 
command can be classified as a server error OR a client error (esp. if the 
client can tell what the server supports).  An unsupported command sounds 
like a 3.14 case ("Unsupported capability") and thats already defined in 
iTIP.

The same goes for the rest of the 6.x thru 10.x cases; they are defined as 
explcit values (ala iTIP) but not as an overall class (ala iCalendar).  I 
think if we consolidate them down and clearly define the 5.x (and 6.x?) 
cases then we can properly reassign them and consolidate accordingly.  In 
any case it needs to be done before Last Call.

This was not a Last Call call, it was a query to see if we should go to 
Last Call.  Dont put the RFC before the draft...

For the longest time your server was sending out CAP issues list postings. 
 Have you gone over that to make sure all are resolved in the latest 
draft??

Yea - I do not care what the numbers are.

I was asked to stop sending it. Perhaps because it was getting old. I
will happily start sending it again.

I stand corrected :-)
It is however nice to get feedback!

Yes I would also not look forward to a 10 year CAP anniversary.
This November will be the 5 year anniversary of capreq-00 publication.

We have two basic choices:

  (1) Fix the missing items - only (Plus only BUSTED items in CAP fixes).
      This would require that we all remind each other of NO CHANGES.
or

  (2) We keep this up for at least a year more to debate how each
      removal/fix is going to be written with MUST/MAY/SHOULD.

Missing:

   BEEP PROFILE:         Any volunteer proposals. (AS in if YES
                         send the *proposals* to the list).

   REQUEST-STATUS codes: I think the text is correct, we just need
                         to fix the numbers associated with those
                         errors.

below are some suggested changes to and questions about
sections 3. through 6. of the cap-10 draft.


(same format as my previous msgs).


<PRE>
----------------------------------------
[23;1273]

   CAP uses beep as the transport and authentication protocol.
            ****
[
intended to be rendered as ``BEEP'' or ``[BEEP]''?
]
----------------------------------------
[25;1363]

   GET-CAPABILITY - Query the capabilities the other end point of the
                                          ^ of
      session.  (Section 10.3)
----------------------------------------
[28;1529]

   Access rights are used to grant or deny access to calendars,
   components, properties, and parameters in a CS to a CU.  CAP defines
   a new component type called a Calendar Access Right (VCAR).
   Specifically, a "VCAR" component grants, or denies, UPNs the right to
                                          X          X
   search and write components, properties, and parameters on calendars
                                          X
   within a CS.
[
not certain of the punctionation rules for or- and and-lists,
but I think at least two of those three commas should not be there.
commas in or- and and-lists seems to be inconsistent in general in the draft.
]
----------------------------------------
[29;1587]

   CARID:REQUESTONLY -  Specifies the "GRANT" and "DENY" rules to UPNs
      other than the owner of the calendar the ability to write new
      objects with the property "METHOD" property set to the "REQUEST"
                       --------calendar
      value.  This CARID allows the owner to specify which UPNs are
      allowed to make scheduling requests.  An example definition for
      this VCAR is:
----------------------------------------
[32;1753]

   capurl   = "cap://" csid [ "/" relcalid ]
   csid     = hostport   ; As defined in Section 3.2.2 of RFC 2396
   relcalid = *uric      ; As defined in Section 2 of RFC 2396
   ***************************************************************
[
this seems to only allow CSID URIs and qualified CalIDs.
should it also allow relative CalIDs?
(looks like 8.36/TARGET and possibly other places say it should)

also, are qualified and relative CalIDs suppose to be special cases of CalID?
because (going back to section 1.3 [9;490]):
   Calendar Identifier (CalID) -  A globally unique identifier
      associated with a calendar.  Calendars reside within a CS.  See
      Qualified Calendar Identifier and Relative Calendar Identifier.
      All CalIDs start with "cap:".
]
----------------------------------------
[skipping 6.1]
----------------------------------------
[51;2832]

   Description: This data type is an identifier that denotes a CU or a
   group of CU.  A UPN is a RFC 822 compliant email address, with
   exceptions listed below, and in most cases it is deliverable to the
   CU.  In some cases it is identical to the CU's well known email
   address.  A CU's UPN MUST never be an e-mail address that is
   deliverable to a different person as there is no requirement that a
   person's UPN MUST BE their e-mail address.  A UPN is formatted as a
   user name followed by "@" followed by a Realm in the form of a valid,
   and unique, DNS domain name.  The user name MUST BE unique within the
   Realm.  In  it's simplest form it looks like "user@example.com".
              -----its

Not entirely.

4.4.3 does not cover the questions like "If my AA DELETEs a VEVENT and 
then I come in and try to modify it, what happens?"  Nor does it address 
all of my posted questions.  Those still uncovered are:

1.1: Do I actually delete a 'marked for deletion' (MFD) entry from the CS 
by reissuing a DELETE with no MARK parameter or is there some other way to 
actually remove it? 
1.3: Can an MFD entry be modified in any way (using the right SELECT, 
etc)? 

2: Must a CS support marking for deletion (and thus soft deletions) or can 
it just do actual deletions? 
2.1: If a CS does not support marking for deletion then should it treat 
the MARK parameter as optional OR should it fail the DELETE? 

3: Is MFD a required feature of a CS or can it just support DELETE but no 
MARK paramter? 
3: If soft deletions are NOT mandatory we need some clear prose to 
describe how implementations that do not support it should respond to soft 
delete requests. 

4: What are the effects of actually deleting an entry and not just MARKing 
it for deletion?   
4.1: Can a CUA just do this arbitrarily or SHOULD a CUA use MARK all the 
time? 
4.2: What is the proper CUA & CS behaviour for dealing with responses to 
either an MFD or actually deleted (irregardless if the CS knows it was 
deleted or if it never existed yet!) entry? 
(4.3 is semi answered but not entirely.)

5: If we cannot unDELETE an entry then why should the CUA distinguish 
between actually deleting it (no MARK parameter) and marking it?  As far 
as the CUA is concerned the entry is gone.  As far as sync goes a sync 
engine just cares if the state is DELETED or not. 

CAP currently has some prose that says how to do exactly what 4.5.5 says 
is NOT covered:

1.3.  Definitions
BOOKED - 
        An object in the calendar store has one of three conceptual 
states. It is in the "UNPROCESSED" state, "BOOKED" state, or marked for 
deletion which is the "DELETED" state. How the implementation stores the 
state of any object is not a protocol issues and is not discussed. An 
object can be said to be booked, unprocessed, or marked for delete. 
[Snip, snip]
        3.      A "DELETED" state entry is created by sending a "DELETE" 
command with the "OPTION" parameter value set to "MARK". To retrieve any 
deleted object, simply do a query asking for any objects that were stored 
in the "DELETED" state. 

and

6.1.1.5.  STATE()
        Returns one of three values, "BOOKED", "UNPROCESSED", or "DELETED" 
depending on the state of the object. Used in a CAL-QUERY "WHERE" clause. 
Where "DELETED" is a component in the marked for delete state. Components 
that have been removed from the store are never returned. 

so #3 and 6.1.1.5 do what 4.5.5 says is not covered.  Guess we need to 
remove it from CAP then (or revise the requirements??)

CAP Requirements are NOT going to RFC so any "Items we are not covering in 
CAP 1.0" should become some part of the CAP RFC so that readers will 
understand why there are apparent holes in the design or unanswered 
questions.  To some extent we have this with lines like:

How synchronization is done is not specified in this memo. 

Perhaps we should fold in the CAP requirements bits on what is "out of 
scope" in to some section so that we set reader expectations accordingly.

If I had more time I would but as it stands now my available WG time is 
dwindling as others start to take the load from me. 

Its definitely NOT just a CAP issue but Id like to make sure that CAP is 
very clear on the issue/usage given the interop issues from iTIP alone.  I 
would dearly love to make sure CAP fixes that oversight before it goes to 
Last Call.

PLEASE include at least 1 (preferably a few more) examples using multipart 
so that CAP readers will have something to get their heads around as they 
implement it (correctly).  Even if it is NOT mine, something rich... 
Please!!

Much of it should be in the CalConnect I - III notes somewhere.  I know it 
was in the notes we sent to Pat/Bob at least once...

It may be a bit old but it still has issues that need to be resolved (or 
marked as resolved) before we can go to Last Call.  After all the intent 
was to make sure we dont overlook any issues, yes?  Maybe we just dont 
need it automated every week...

Im sure that some issues are not on it as the list has not been updated 
publically since 2001 but we should fix that too...

I have been adding all CALSCH minutes to an indexed database on my server.
In the process, I found minutes from Atlanta, 2002.  There is a section on
the Agenda where the editors of the iSIP draft did talk about their work.
Since I did not attend the Atlanta meeting - I did not realize this had
happened.  So, my apologies to the editors of this draft regarding my "this
is news to me" note.

On that note, this is a good start - and I want to make sure I say to the
list that the draft editors have tried to talk about their work.  However,
there still is no discussion on the list.  I think if everyone reads this
draft (http://www.ietf.org/internet-drafts/draft-pessi-ical-isip-01.txt)
and then comment if they "don't like it" then that is goodness.  I still
have a problem with the draft saying it is one of our works.  In fact, with
no discussion on the list, and with nothing in our charter, it can not be
called one of our drafts.  So, that wording either needs to be removed from
the draft.  This will not be added to our charter.  We are trying to close
down - not add new drafts.  Hope that helps clear up a bit of things.

Can anyone get me up to speed on the issues relating to models and 
implementations of events which span a day boundary?  Every user-agent 
(most recently Mozilla Calendar) I recall using doesn't seem to be able 
to handle what seems to me to be such common use case.  I guess there's 
a good reason for that?

iCalendar has no such restriction. It is a vender issue.

I'm wondering whether you have to include a vtimezone component for
each vcalendar according to RFC 2445. You can certainly point to a
TZURL:

"The optional "TZURL" property is url value that points to a published
VTIMEZONE definition. TZURL SHOULD refer to a resource that is
accessible by anyone who might need to interpret the object. This SHOULD
NOT normally be a file: URL or other URL that is not widely accessible."
(RFC 2445 4.6.5 Time Zone Component)

- so can we just point to the descriptions of VTIMEZONES we already have
in separate files?

(we have them in RDF: http://www.w3.org/2002/12/cal/tzd/)

thanks for any pointers, and sorry if I've missed something.

cheers

Libby

Yes, this is a 'must'. See section 4.2.19 in RFC 2445, Time zone 
identifier definition.
"An individual "VTIMEZONE" calendar component MUST be specified for 
each unique "TZID" parameter value specified in the iCalendar object."
And STANDARD and/or DAYLIGHT must also appear in the timezone 
definition, so a simple TZURL won't be enough.

I guess I was just being picky, but could not 'specified' just be
'pointed to' using tzurl? Just a thought..

But the ABNF is clear that you MUST have at least one of standardc or 
daylightc.

I'm not sure why TZURL exists, actually.  Putting your timezone 
definition outside the iCalendar is a good way to get people to show up 
for the event at different times.

ok, thanks for the info everyone.
In an RDF context it would make sense to point to it, but I can see why
you might want to put it in the file as well.

	appropriate? Do you feel that iSIP should be a CALSCH WG item?

	In any case I'd like to keep the iCalendar people aware of the

	would cause problems to iMIP or CAP. The discussion can always
	be redirected to a more appropriate mailing list, if required.

There are no issues in iCalendar like this.  Entries can span any length 
of time desired.

Probably its not easy/clean/simple way to render an entry that starts at, 
say, 7:15PM today and ends at 11:30AM tomorrow in a way that wont confuse 
users (in addition to rendering other normal sized entries as well).  ("Is 
that start time 7:15 yesterday or the day before??"  "There is so much to 
try and squeeze into the UI that realestate is at a premium...") 
Eventually we may have a good example of how to do it but so far noone has 
seemed to find a solution for it.

For those of you interested, and/or could not attend the CALSCH meeting,
there is a log of the jabber discussions located at
http://www.jabber.com/chatbot/logs/conference.ietf.jabber.com/calsch/
.
In addition, the power point pages have been saved as text to a page on my
website - temporarily - until they show up on the IETF pages.

PS. Most Australian current affairs and news is produced on the east
    coast (UTC+10) - occasionally they refer to an event happening at
    say 8pm Australian time - which completely wrong for the part of
    of Australia (the west) which I live in which is UTC+8 ....

Folks - it is very important that any feedback to the -10.txt version of
the draft come in soon. Our plan is to be done VERY soon. We are looking
for things that are BUSTED.

What will be in the -11.txt version that we hope will be the LAST CALL
version. We will be doing the last "last call" *SOON*!

	Sorting will be removed and will be submitted as a separate draft.

	Saving of VQUERY's will be removed. we will keep the QUERYID
         property in reserve so that it can be added later in a separate
         draft.

         Clarify that marked for delete is the old tombstone flag and
         is only (currently) used for the unspecified synchronization.
         Clarify that it is unspecified how/when you clean those out.
         Clarify that un-delete is unspecified.

         Adding a MULTIPART example (thanks Bruce).

         Typo fixes, ABNF fixes, and miscellaneous grammar fixes.

The CALSCH meeting in San Francisco was interesting as were the
hallway, and dinner talks.

By directive from the IETF area directors - CAP will be shipping *SOON*.
Any changes from this point forward will require a HUGE majority before
being considered for the -11.txt version. There are over 300 subscribers
to this list and a handful of requests is not a huge number. Please
do not shoot the messenger :-)

Thanks for all of the responses, in summary:

* Not an iCalendar constraint.
* Ximian Evolution implements it and renders it pretty well.

Hi,
I'm looking at the xCal specification
(http://www.ietf.org/internet-drafts/draft-ietf-calsch-many-xcal-02.txt),
and had a question regarding the attach property.
The definition of the attach XML is:
          <!ELEMENT attach (extref | b64bin)>
          <!-- extref holds a reference to an external entity that -->
          <!-- has the attachment. b64bin holds the inline BASE64 encoded 
-->
          <!-- binary data for the attachment as defined in RFC 2045. -->
          <!ELEMENT extref EMPTY>
              <!ATTLIST extref uri ENTITY #REQUIRED>
          <!ELEMENT b64bin (#PCDATA)>
              <!ATTLIST b64bin fmttype CDATA             #REQUIRED>
              <!ATTLIST b64bin value   NOTATION (BINARY) #IMPLIED>

My question is: is the fmttype an attribute of only binary attachments, or
can it also be the attribute of a uri attachment?
by reading the iCalendar spec I understood it was the latter, but this is
not reflected in the XML definition.

The xCal mailing list is 'xcal-dev@inet-consulting.com'.

To subscribe:
	xcal-dev-request@inet-consulting.com

I have Cc'd that list and set the reply-to to be that list for this message.

In the newest (being edited an not yet sent) xcal: all components are tags.
                     all properties are tags.
                     all parameters are tag attributes.

The mapping is 1:1 to iCalendar, so if it is valid in iCalendar
it is valid in xCal. If it is invalid in iCalendar, it is invalid
in xCal.

This is a multipart message in MIME format.
--=_alternative 006FA68A85256CFA_=
Content-Type: text/plain; charset="US-ASCII"

Its unclear in the latest drafts so I wanted to ask the WG at large 
something.  Does CAP allow for a CUA to get busytime from the CS? 

The first paragraph in Section 1 says in part: 

             It further specifies how to search for available busy time 
information. 

but I dont see any prose that actually says how this is to be done in CAP. 
 All of the commands and examples appear to be oriented at entry 
creation/discovery/deletion but nowhere does there appear to be 
consideration of something like "How do I get Pats, Bobs and Dougs 
busytime?" 

Im merely guessing that I could SEARCH for it but all the examples/prose 
talk about entries like VEVENTs and VTODOs.  Since busytime is NOT an 
actual entry but rather a conceptual thing ("Take all of Bruces entries 
for today and that is his 'busytime' for today") Im unclear how (or even 
_if_) busytime is addressed in CAP.  Yes we have VFREEBUSY components but 
they are most typically synthesized by the system by amalgamating the 
other entrys rather than being an actually separately maintained _actual_ 
component. 

I may infer from the text under CREATE that I (or my CUA) must CREATE the 
VFREEBUSY for it to exist (see create-vreply and create-comp).   

I may also infer from the text under DELETE that I can delete VFREEBUSY 
data but not the actual entry that it represents (see delete-vreply) which 
can also cause some serious quandries ("The VEVENT is in my Calendar but 
it does not appear to be reflected in the VFREEBUSY data that I retrieved. 
 Why not?") 

Im more than a bit confused as to the usefulness of 'moving' VFREEBUSY 
data around since breaks any linkage means of relating the entries in the 
VFREEBUSY to any possible entries in a users calendar.  Why would I need 
(or even _want_ ) to move _my_ VFREEBUSY data onto, say, Pats calendar?? 
 Doing so would make it relevant to Pat and not me, right??... 

Beyond the cited 3 commands above there is no text or hints on "how to 
search for available busy time information." as promised in Section 1. 

Does anyone else share this confusion or am I just missing the obvious?

Yeah...it would probably make sense for the CS to synthesize the 
VFREEBUSY on the fly, in response to a query.  That'll complicate access 
control; do we have a way to say "Joe can't read my calendar, but he can 
read my freebusy"?

The same as with iTIP. You publish yours and make it available.

And you will notice that VFREEBUSY is in the ABNF for SEARCH.

We deferred 'roll-up' into VFREEBUSY. Yes it is unspecified. It would
be an unspecified CUA-BOT.

Yes.

TRANSPARENT entries will also not show up in your VFREEBUSY.
Plus if you don't what that, do not allow a CUA or CUA-BOT to do that.

CAP commands do not map 1-to-1 onto iTIP messages. 

In CAP I CREATE a component in one or more TARGETs which may have some 
METHOD property value.  In iTIP I send a message with a METHOD property 
value determined by iTIP.  CAP always uses CREATE to create new entities 
(hmm, how do updates happen!)

For busytime, iTIP uses the VFREEBUSY component with METHOD:REQUEST or 
METHOD:REPLY for requesting and responding, respectively.  In CAP, I guess 
that would crudely map to a CREATE command with particular TARGETs but 
there is NOTHING to lead me to belive that the CS must do any actual 
processing beyond the actual request creation. 

Nothing in CAP says that the CS works in realtime to process the VFREEBUSY 
with METHOD:REQUEST as a realtime busytime lookup and as such SHOULD 
result in busytime results being sent back rather than 
"REQUEST-STATUS:2.0;VFREEBUSY Created" response.  As such if my CUA 
CREATEs a VFREEBUSY with METHOD:REQUEST, all I get back is essentially a 
"Yes, your VFREEBUSY was created in the TARGET", NOT the actual results Im 
querying for!  So how does my CUA get the RESULTS of the workflow query?? 
CAP is realtime so I would assume that the query / response for busytime 
would/should be realtime too!

Actually it is not.  The only ANBF in SEARCH is: 

        search-cmd   = searchparam ":" "SEARCH"

       searchparam   = *(

                     ; the following are optional,
                     ; but MUST NOT occur more than once

                       id-param
                     / localize-param
                     / latency-param

                     ; the following MUST occur exactly once and only
                     ; when the latency-param has been supplied and
                     ; MUST NOT be supplied if the latency-param is
                     ; not supplied.

                     / action-param

                     ; the following is optional,
                     ; and MAY occur more than once

                     / other-params

                     )

Not a single mention of VFREEBUSY.  In fact the ABNF under search is 
incomplete compared with the ABNF under DELETE and CREATE which have 
create-vreply, create-vresponse, etc. but thats a different matter.

So the text from Section 1 is wrong; we do NOT provide a clear way to do 
realtime busytime lookups...

Given that a CUA can create VFREEBUSY and query for them, etc I strongly 
suspect that VFREEBUSY and its use has been overlooked or ignored.  What 
good is a calendaring and _SCHEDULING_ protocol if I cant get your 
schedule information??

If we treated VFREEBUSYs as 'meta' information instead of an actual 
component that can be crated/updated/modified by a CUA and thus NOT 
reflect the actual busytime of the TARGETs then I think its a step closer 
to being better.  Otherwise we totally misconstruct the busytime ablities 
in CAP to be totally useless compared to those in iTIP (where we assumed 
the data to be generated dynamically rather than statically and CERTAINLY 
NOT modifiable by the requestor/CU).

If we are going to defer it then we should put in some prose to that 
effect so that its clear that CAP 1.0 does not accuratly provide a 
busytime lookup mechanism.

Ugh, see above about iTIP vs CAP in this respect...

They show up with the proper fbparam property parameter on each FREEBUSY 
within the VFREEBUSY.  Go check 4.8.2.6 Free/Busy Time of 2445.

&gt; &gt; talk about entries like VEVENTs and VTODOs. &nbsp; Since busytime
is NOT an<br>
&gt; &gt; actual entry but rather a conceptual thing (&quot;Take all of
Bruces entries <br>
&gt; &gt; for today and that is his 'busytime' for today&quot;) Im unclear
how (or even <br>
&gt; &gt; _if_) busytime is addressed in CAP. &nbsp;Yes we have VFREEBUSY
components <br>
&gt; &gt; but they are most typically synthesized by the system by amalgamating
<br>
&gt; &gt; the other entrys rather than being an actually separately maintained
<br>
&gt; &gt; _actual_ component.<br>
&gt; <br>
&gt; We deferred 'roll-up' into VFREEBUSY. Yes it is unspecified. It would<br>
&gt; be an unspecified CUA-BOT.<br>
</tt></font>
<br><font size=2 face="sans-serif">So the text from Section 1 is wrong;
we do NOT provide a clear way to do realtime busytime lookups...</font>
<br>
<br><font size=2 face="sans-serif">Given that a CUA can create VFREEBUSY
and query for them, etc I strongly suspect that VFREEBUSY and its use has
been overlooked or ignored. &nbsp;What good is a calendaring and _SCHEDULING_
protocol if I cant get your schedule information??</font>
<br>
<br><font size=2 face="sans-serif">If we treated VFREEBUSYs as 'meta' information
instead of an actual component that can be crated/updated/modified by a
CUA and thus NOT reflect the actual busytime of the TARGETs then I think
its a step closer to being better. &nbsp;Otherwise we totally misconstruct
the busytime ablities in CAP to be totally useless compared to those in
iTIP (where we assumed the data to be generated dynamically rather than
statically and CERTAINLY NOT modifiable by the requestor/CU).</font>
<br>
<br><font size=2 face="sans-serif">If we are going to defer it then we
should put in some prose to that effect so that its clear that CAP 1.0
does not accuratly provide a busytime lookup mechanism.</font>
<br>
<br><font size=2><tt>&gt; &gt; I may infer from the text under CREATE that
I (or my CUA) must CREATE <br>
&gt; &gt; the VFREEBUSY for it to exist (see create-vreply and create-comp).
&nbsp;<br>
&gt; <br>
&gt; Yes.<br>
</tt></font>
<br><font size=2 face="sans-serif">Ugh, see above about iTIP vs CAP in
this respect...</font>
<br>
<br><font size=2><tt>&gt; &gt; I may also infer from the text under DELETE
that I can delete VFREEBUSY <br>
&gt; &gt; data but not the actual entry that it represents (see delete-vreply)
<br>
&gt; &gt; which can also cause some serious quandries (&quot;The VEVENT
is in my <br>
&gt; &gt; Calendar but it does not appear to be reflected in the VFREEBUSY
data <br>
&gt; &gt; that I retrieved. &nbsp;Why not?&quot;)<br>
&gt; <br>
&gt; TRANSPARENT entries will also not show up in your VFREEBUSY.<br>
&gt; Plus if you don't what that, do not allow a CUA or CUA-BOT to do that.<br>
</tt></font>
<br><font size=2 face="sans-serif">They show up with the proper </font><font size=2><tt>fbparam</tt></font><font size=2 face="sans-serif">

In fact we squashed the CS from doing any work for the CUA.
You need to have your CUA or a CUA-BOT do it for you.

Read more text...:

      comp-name  = "VEVENT"  / "VTODO"     / "VJOURNAL" / "VFREEBUSY"
                 / "VALARM"  / "DAYLIGHT"  / "STANDARD" / "VAGENDA"
                 / "VCAR"    / "VCALSTORE" / "VQUERY"   / "VTIMEZONE"
                 / x-comp    / iana-comp


And comp-name is used in:

   cal-query  = "SELECT"   SP   cap-val  SP
                "FROM"     SP   comp-name SP
                "WHERE"    SP   cap-expr
