Dear all,

this topic seems to have gone asleep since a while.

Can anyone provide me information on the process of suggesting changes 
to the RFC 6838 (Media Type Specifications and Registration Procedures)?

thanks in advance.

Paul

Post a new draft with the new template(*)? I can't promise that there
would be enough energy to get the update done, but seeing something
concrete would certainly help.

(*) - if you never done this, contact me off-list.

Thank you,
Alexey

I don't see a problem with a draft updating the template. Pretty low cost thing
to do. OTOH, nothing prevents a registration from including "additional"
additional information, nor is a registration precluded from omitting any or
all of the additional information fields.

So the value of formally adding the fields would be if it gets people to
list them when they wouldn't otherwise. Given past experience I'm skeptical
this will happen.

That’s pretty clear and it seems like, such an actualisation is 
probably useful to at least give a hint that clipboard types may be 
relevant.

Well, on this, I think it does depend a lot on the type.
Sometimes it makes no sense (to all or to some) to make consider put 
this into a clipboard (e.g. because a selection does not make sense) and 
for these, the authors will simply ignore it. At least, it seems to me 
that clipboard type names make more sense than Macintosh 4-letter codes.

thanks

It's not a question of what makes sense, it's a question of the information
people have available and thus what they are able and willing to put in a
registration.

Past experience says people are unlikely to go the extra mile to think
about any of this stuff even if we prompt them for it.

Speaking from experience, it occurs to almost no one to think about a
clipboard type name and then wedge it into an unreceptive form. I
believe that the folks who fill these out are pretty diligent. Clearly
marking optional fields as such and providing links to understand,
e.g. clipboard type names, allows said diligent netizens to leave less
interop to chance, which is why they're filling out the form in the
first place.

Some are. Many are not.

Having seen every registration that has come in for the past 10+ year, I
speak with some authority here.

Again, I have no objection to adding such fields if people want to spend
the time to do so. However, my skepticism as to their utility remains.

Hi,

I am new to this list, and hope I do not misunderstand its purpose.  I
would like to suggest a "new" mime type, and hope for your input on the
topic.

While testing a archive system on a subset of mails from the Debian
archive, I noticed the following unregistered MIME types on the top ten
list of MIME types used in the emails: text/x-patch and text/x-diff.

The fact that emailing patches as attachments is so popular make me
suspect it is time to register a MIME type for it.  But what type should
the suggested?  One of the above, or a new one without the x- prefix?

I think this negotiation must happen with the tool maintainers which
currently recognize text/x-{patch,diff}. Given that that's probably
impossible, the answer is almost certainly that you are stuck with
"x-". Thanks for picking this up.

I tried to answer your question but ended up puzzled by this text in
[RFC6838]:
[[
   Note that types with names beginning with "x-" are no longer
   considered to be members of this tree (see [RFC6648]).  Also note
   that if a generally useful and widely deployed type incorrectly ends
   up with an "x-" name prefix, it MAY be registered using its current
   name in an alternative tree by following the procedure defined in
   Appendix A.
]]

The only "x-" subtree in [IMT] is "x-www-form-urlencoded", and maybe
it's an exception. The tricky question is whether x-{diff,patch}
deserve the same exception. On one hand, we don't want a slippery
slope of exceptions, on the other hand, the tree's job is to document
current or achievable reality.

If an application includes extensions and/or Mac file type codes, is the

I'm looking at:

3. File extension(s): various media file types, such as .mp4, .mov, .mkv,
etc.

...and wondering if we're happy with that.

I have no idea how to identify the tool maintainers which currently
recognize text/x-{patch,diff}.  Perhaps at least the maintainers of
http://www.gnu.org/software/diffutils/ and
http://savannah.gnu.org/projects/patch/ are relevant contributors to
such discussion?  They do not really use or recognice MIME types, being
command line tools, but are responsible for the typical producer and
consumer of these files.

On Debian systems, text/x-patch and text/x-diff are set to be aliases
for each other, with text/x-patch being the primary one, according to
the /usr/share/mime/packages/freedesktop.org.xml file provided by the
shared-mime-info package.  I guess this provide one data point for
preferring text/x-patch over text/x-diff as the official MIME type.

Personally I would prefer to move to text/patch for the official MIME
type as diff produces a patch in text format, which I believe text/patch
expresses better than any of the alternatives.

I notice you mention application/*.  Is not text/* a better choice,
given that for example patches in emails could be shown directly in the
email and do not need a "viewer" to be readable to those of us receiving
patches?

custodians of the IANA register if any update should happen. :)
