<erik> +1

all: yes

erik: Michael, will you be able to go to Seoul?

Michael: no, other obligation

erik: will get back to the f2f issue next week
... on action-92, postponed until spec is out
... philippe said publication would be ok today or tomorrow. We wait.

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

erik: what do you all think of current state of the spec?

michael: comment on section 5 needs addressing

jack: wants to think about forward compatibility.
... forward compatibility is tricky: should have a way whereby newer implementations can retroactively
... tell older implementations to fail or ignore new feature

erik: michael, did Yves suggest we need an implementation?

michael: right
... let's address in the next draft

jack: +1

<erik> +1

conrad: yes, publish now

erik: how many implementations do we have? Ours
... yves has one

jack: mine is rusty. Will brush up in coming few weeks.

erik: silvia? conrad? implementations?

conrad: have uri handling, not full syntax yet. In the next few months.
... will work with silvia and ogg community

erik: we have server-side implementation.
... is up for testing, will post url.

<scribe> ACTION: erik to get URL for MF server, and post to group [recorded in http://www.w3.org/2009/11/25-mediafrag-minutes.html#action01]

<trackbot> Created ACTION-120 - Get URL for MF server, and post to group [on Erik Mannens - due 2009-12-02].

2 - short name issue

erik: should we omit -spec?

michael: yes

<silvia> I have client side implementation with HTML5

jackjansen: so we use short name for spec, and add suffices for aux documents

all: yes.

ACTION on Raphael to fix document names

<trackbot> Sorry, couldn't find user - on

ACTION Raphaël to fix document names

<trackbot> Created ACTION-121 - Fix document names [on Raphaël Troncy - due 2009-12-02].

TOPIC 3.1 media fragment syntax

erik: lets keep for next week

3.2 HTTP

erik: again, let's table

3.3 - track and id handling

erik: COnrads proposal, http://www.w3.org/2008/WebVideo/Fragments/wiki/Server-parsed_Fragments

silvia: need to wait on section 5 to be done.
... may jump in myself.
... Raphaël was working on section 3, don't think on 5 yet
... I will coordinate with him if I also start to edit.

erik: I will ping Raphaël.

silvia: we are missing all our publishing windows.
... and section 5 really needs work before publishing, to reflect changes to 3.

michael: should we really wait until 5 is complete?

silvia: yes, it contradicts 3 at the moment, I will look over it.
... three sections in section 3 have no counterpart in section 5
... must be fixed.
... cannot publish now, action-112 needs to be fixed.

michael: silvia, can you take this offline with Raphaël?

erik: I will call Raphaël today, tell that Silvia does not want to publish until action-112 and
... section 5 issues are resolved.
... I will send an email tonight on what the status is.

silvia: if it is needed I can put in time this weekend.

3.4 discovery of track and named fragments

silvia: I wrote about this in my blog.


<erik> rssagent, draft minutes

jack: not sure if the blog post doesn't need to be split into two: mechanism (roe, mpeg-21) versus
... application (semantics)
... thinks only mechanism is relevant to MF
... will try to write something up.

erik: will get back to it next week.
... Let's adjourn.


see you next week!

<mhausenblas> hm, seems Zakim didn't pick up the attendees
