resolved: 44


<raphael> close ACTION-44

<trackbot> ACTION-44 Take care of zakim bridge for F2F closed

raphael: next issue: meeting at TPAC or not? Maybe we don't want to fly there in November, too expensive?

Silvia: I probably won't make it

Thierry: annotations WG probably will meet

Raphael: suggests we meet at a cheaper place. Hotels in California are more expensive, and there's a fee too.
... next topic: teleconf time. Heads up that next weeks teleconf is an hour early too.

Silvia: back to f2f: maybe I can arrange something through csiro?

Raphael: lets postpone discussion to Barcelona. For now main point is meeting at TPAC or not (to meet other groups)


<raphael> http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-reqs/

raphael: some people seem to have CVS problems.

Silvia: yes, I do.

raphael: various people have no problems.

<tmichel> I have also sent an email to the system about checking in documents

<nessy> http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-reqs/

<erik> Erik: still problem (probably authentication issue)

Silvia: where is the document?

Michael: overview.html

Raphael: html does not match xml. Needs to be processed by stylesheet.

<raphael> Thierry has filled the section 3, I will checked it in

Raphael: cvs up should give you updated documents
... back to syntax.

<raphael> http://www.w3.org/2002/09/wbs/42785/MFRAGSYNTAXSEGMENT/

Raphael: The questionaire.
... Everyone happy with segment, which has the majority?

<mhausenblas> +1

<raphael> close ACTION-45

<trackbot> ACTION-45 Erik And Raphael to set up a questionnaire to find a name for the top level Media Fragment production rule closed

yves: does this also change the other production names?

Raphael: I think so. xxxfragment becomes xxxsegment for any xxx.
... Action 46 is ongoing.

yves: had no time to work on it. In another f2f.

2.2 use cases

Silvia: working on it, seems ok so far.

Topic 2.3: existing technology.

s/Topic 2.3: Topic: 2.3

erik: only need to do copying.

<raphael> close ACTION-23

<trackbot> ACTION-23 (together with Jean-Pierre) to add TV-Anytime also to Existing Technologies Survey closed

2.4 http implementation

<raphael> http://www.w3.org/2008/WebVideo/Fragments/wiki/HTTP_implementation

Raphael: need to use real media. Jack suggests using prerecorded video from Nice
... Does current text capture intention?

Yves: think so, need to check

Silvia: me too

Raphael: need to fill pro+con section, especially caching.

<raphael> Jack: suggest to flip the examples ... 4-ways handshake is better equiped to have different ranges

<raphael> ... while the 2-ways handshakes might return exactly what the UA has requested, and the UA will need to do an extra clipping

<raphael> Yves: multi mime answer?

<raphael> Jack: we do continuous segments or not?

<raphael> Raphael: see the issue page http://www.w3.org/2008/WebVideo/Fragments/wiki/Issues#Continuity_.2F_Discontinuity

Silvia: I want to reopen the discussion on 2way 4way
... maybe at next f2f.

<raphael> Raphael: agree to make it a major topic of our next telecon

Silvia: not reopen, more like clarify.

<Yves> btw: http://tools.ietf.org/html/draft-ietf-httpbis-p5-range-06

Raphael: Silvia, can you write an email with your comments?

Silvia: better to have everyone read it, and discuss it in 2 weeks time

Raphael: ok.

Silvia: will miss next week: product lunch
... (OR LAUNCH??)

<nessy> yeah, product launch :)

Raphael: Yves, what is the url you posted above?

(offtopic: too bad, lunch seems more fun)

Raphael: it's mandatory reading for everyone.

3. issues

Raphael: do we need to update mimetype registrations?

Michael: not necessary for first draft. I haven't done anything yet, but please keep it open.
... will come with proposal after talking to various people.

<raphael> +1 for Michael

<nessy> +1

Raphael: ok, should we keep it on agenda?

Michael: don't care

Raphael: on to issue 4. Track names.

Silvia: I'm both pro and con, actually.
... con because its up to the containerr
... pro because it's handy from user pov

<raphael> Jack: I'm also pro and con

<raphael> ... I'm against it at this point in time

<raphael> ... I'm afraid we standardize it incorrectly

<raphael> ... we are going more in the metadata field

<raphael> Raphael: agree, we might need more expertise and postpone that later

<raphael> Jack: I suggest we study it more, particularly the WAI

<raphael> Raphael: should we try to invite some of them in a telecon?

Raphael: I'll put it on the agenda for the next cross-wg teleconf with them
... but after first working draft.

<raphael> Jack: yes, but put a paragraph explaining the rationale in the WD

<raphael> +1

<nessy> +1

<davy> +1

5. AOB

Raphael: nothing on implementation. AOB?
... Nothing? Ok.
... Everyone needs to read http document.
... Also: everyone take care we copy all info to wd.

Michael: asks Yves to give occasional updates on httpbis

Yves: info is publicly available in minutes.

raphael, are you doing the magic?

Ah, yves does.
