IETF draft on MIME

not everyone up to speed

masinter: section 1 the web uses mime, section 2 history, 3 problems
... maybe i should combine 3 & 4
... they're trying to say what's wrong, why we have a problem
... section 5, what kinds of fixes could we apply? (without going into specifics)
... that's the overall plan. there were other comments i got that i didn't know what to do with
... differences were not significant or major
... procedurally better if we don't get everything in here perfect.
... I would like people to check to make sure that what I've said makes sense

yves: HTML5 is calling for violation of rules stated in mime registry; that is an issue
... fragments and mime types [?]
... need to find ways to document issues with already registered mime types. not easy to do

masinter: Does the document explain the issues well enough? are the proposed list of things to fix complete?
... I thought these things were mentioned in the draft. If not need to fix

yves: polyglot. text vs. image. the case of SVG if labelled as image/svg+xml or application/xml

masinter: things missing, or incorrect statements of problems / fixes?
... Maybe it's close to being done for now.
... how about if we talk about it on a telcon after the f2f

<noah> ACTION-472 to be discussed in future telcon, with aim of getting agreement to push forward..f2f time not needed.

ashok: It's a nicely written paper
... There were a couple things related to client side state work. Many registrations don't describe semantics of fragids...

<Ashok> A possible solution is to amend the definition in the media types that accept "active content" in them, like HTML and SVG, to acknowledge the fact that fragments might also be used (if not in contradiction with the 'static' use of those fragments) for programmatic purposes.

ashok: and maybe registrations should say something about active content?
... I didn't figure out where you came out on magic numbers - against, for, useful in addition, what?

masinter: In many contexts all you have to go on is the magic number. A heuristic that in many contexts is essential.
... There are situations where the mechanism of transmitting mime types hasn't been effective.
... Need to be clearer on what they're for. The sniffing doc has moved from being individual submission, to work item of security WG
... Need to think about authoritative metadata and sniffing
... sniffing isn't enough
... lots of confusion around language versions. sniffing doesn't tell you which version
... collisions in magic-number-space

<johnk> sorry, I have to leave early today

noah: do we need to go into this detail here? sniffing seems like a separate discussion

masinter: I want the doc to gather in one place all these related problems

noah: servers should do the right thing, because ...

masinter: Want to increase the scope of the document
... include charsets, talk about context in which mime types are used
... Doc can identify problems without solving them

raman: Talking about sniffing in this doc is unavoidable. you have to.

<Zakim> NoahM, you wanted to talk about self-describing Web and authoritative metadata

masinter: ready for detailed change suggestions; or new topics

noah: please lead the process that will lead to a decision to bless

<noah> ACTION-472?
