Dear all,
The minutes of today's telecon are available for review at
http://www.w3.org/2010/09/22-mediafrag-minutes.html (and in text format
below). We haven't been able to make progress for months because we
cannot have everybody on the phone when we need.
We need to resolve ASAP the question of extensibility for Media
Fragments. Philip will start a new thread on the mailing list. Please,
all, react asap on this thread and express your view. We will take a
resolution next week so please, try to make it.
Cheers.
Raphaël

I have not yet done this for IETF, TAG
3. MEDIA FRAGMENT EXTENSION:
Erik: no more news from Michael/Conrad should we be concerned?
Raphael: I don't think so ... there are no critical actions from
them we depend on
... if they can provide feedback, it's good
... we must progress without waiting
Philippe's proposal:

Philippe: this is just one part of the problem
... we could include this piece of ABNF in the doc
ACTIOn-173?

check the grammar of both the URI syntax and the Headers syntax --
due 2010-06-22 -- OPEN

spec itself -- open

Yves: action is still pending
... what I would like to have is what goes in the javascript stack
from the browsers when they meet a %encoded URL
... %encoded and html-encoded URL (with ampersand)
Erik: is this browser independent?
<foolip> html entities: &
<foolip> percent encoding: %64
Philippe: this never reaches javascript, this is handled by the HTML
parser
... for percent encoding, yes, the js sees the un-decode string
Yves: could you send to the mailing list the tests you have made so
we can test on another browser than Opera
Philippe: sure
<scribe> ACTION: philippe to send his list of test cases to the
mailing list for understanding how browsers handle %-encodded and
html-encoded URL [recorded in

<trackbot> Sorry, couldn't find user - philippe
<foolip> Philip
<scribe> ACTION: philip to send his list of test cases to the
mailing list for understanding how browsers handle %-encodded and
html-encoded URL [recorded in
[17]http://www.w3.org/2010/09/22-mediafrag-minutes.html#action03]
<trackbot> Created ACTION-186 - Send his list of test cases to the
mailing list for understanding how browsers handle %-encodded and
html-encoded URL [on Philip Jägenstedt - due 2010-09-29].
Erik: what's happened if browsers manage this inconsistently?
Raphael: the related problem deals with extensibility
... of the URI syntax
Philip: the whole thing is to have a break into name/value pairs
... and then be relaxed if you don't understand all name/value pairs
... I think we should have a syntax, that mandates what we should
have as name/value
... parsers fail for typos
... but implementations should be more relaxed
Yves: what bothers me that the ABNF tells both what the syntax is
and how to parse it
... the big issue is something that is not a media fragment can be
recognized as a Media Fragment
<foolip> "parsers fail for typos" isn't correct
<foolip> a validator would, but not a parser in a browser
Yves: we could put an algorithm for the browser
... we need to decide first what to do with extensibility
... then I don't see problem of having the algo closed to the ABNF
definition
... so Annex D will move up towards the formal grammar
Erik: I will not make the parsing instructions normative, they are
useful guidelines only
Philip: if we need to valid the whole URI before, then parsers will
be broken with version 2
Yves: yes, but if the new thing means already something you're
already into trouble
<silvia> ping?
Yves: I agree
s/agrre/agree with Philip
Raphael: could we just write a normative paragraph that states how
the parser should behave ?
Erik: a lot of test cases would need to be redefined
Yves: I want to have everybody on the phone to agree what we want to
do with extensibility
<Yves> I would note that we can try to get agreement on the ML in
the meantime
<scribe> ACTION: Philip to start a new thread about extensibility of
the Media Fragments in order to get consensus by next week [recorded
in [18]http://www.w3.org/2010/09/22-mediafrag-minutes.html#action04]
