<trackbot> ACTION-66 Look at the organisation of the 4th F2F meeting in Amsterdam on September 17-18 (just after IBC) closed
raphael: what shall we do jackjansen?
jackjansen: not so much in a
hurry. after IBC things here in A'dam are normal again
... that is we can wait a bit
raphael: so we can wait till end of June
jackjansen: silvia, we didn't
pick the slot due to IBC in the first place
... but we wanted to have somethin in 09/2009
... other question. is any other place/time doable for the
Aussies/SAfricans?
raphael: alternative proposal was SAMT09, Graz, Austria
Michael: not sure if it makes sense to rehash that topic
raphael: we will ensure to have
more virtual meetings as well
... the September meeting is still an option
... will be decided by end of June
raphael: no progress so far, will be done ASAP
<conrad> http://www.w3.org/2008/WebVideo/Fragments/wiki/UA_Server_HTTP_Communication#Conrad.27s_proposal
UA Server HTTP Communication (Conrad/Raphael)
conrad explains his proposal
raphael: question regarding
Accept-Range-Refer is similar to the original proposal?
... how is the conversion between sec and bytes done
<conrad> bah
<raphael> My first observation: Accept-Range-Refer ~= Accept-Ranges AND Range-refer ~= Range HTTP headers
Michael: same here
<Gui> what I remember from Conrad proposal is : 1. clarification on the order of fallback mechanisms and 2. more verbose HTTP headers
raphael: 1. question is sec to bytes conversion
conrad: Server is authoritative re conversion
silvia: we should have a
comparison of the three proposals on the table
... and having Yves on board would certainly help
raphael: now we should focus on the # solution, move ? to the bottom
jackjansen: I think we should keep the two as it might help establishing backwards compatibility, right conrad?
conrad: correct
raphael: ok, but we still need an
overview table comparing the proposals
... I also miss the number of roundtrips
... seems always one, no?
conrad: no, there are further requests
ACTION-63?
<trackbot> ACTION-63 -- Conrad Parker to update the Wiki with his more general approach with precisely the same examples -- due 2009-04-23 -- OPEN

<trackbot> Created ACTION-80 - Provide some rationalee and use cases for his proposal [on Conrad Parker - due 2009-05-27].

ACTION-79?
<trackbot> ACTION-79 -- Michael Hausenblas to summarise the options for 4xx status code for empty TC0002-0007 in a Wiki page -- due 2009-05-20 -- OPEN

<trackbot> ACTION-79 Summarise the options for 4xx status code for empty TC0002-0007 in a Wiki page closed
Michael: see http://www.w3.org/2008/WebVideo/Fragments/wiki/TestCasesDiscussion
PROPOSAL: In case an 'empty response' (such as found in TC0002-0006) occurs, the origin server MUST send an HTTP 416 status code if and only if the fragment range was given in an HTTP Range request header, otherwise a HTTP 406 status code MUST be send.
Michael: beside not knowing of other usages of 416/406 ...
jackjansen: has it already been decided to be 4xx??
<conrad> :)
jackjansen: why not using 204?
<davy> I think range 20-10 is the same error as 0-0 if we specify that the start has to be smaller than the end
<raphael> Discussion about what *is* an empty fragment?
<raphael> 204: a valid fragment but no content
<raphael> 4xx: an error, because the UA has nothing to present
<conrad> yeah :-(
<scribe> ACTION: Michael to update the TC discussion page with 204 proposal and ask Yves's opinion on the list [recorded in http://www.w3.org/2009/05/20-mediafrag-minutes.html#action02]
<trackbot> Created ACTION-81 - Update the TC discussion page with 204 proposal and ask Yves's opinion on the list [on Michael Hausenblas - due 2009-05-27].
ISSUE-3?
<trackbot> ISSUE-3 -- Does our MF URI syntax imply that we need to update MIME Type registrations? -- OPEN
<trackbot> http://www.w3.org/2008/WebVideo/Fragments/tracker/issues/3
ISSUE-4 ?
ISSUE-4?
<raphael> ACTION-73?
<trackbot> ACTION-73 -- Conrad Parker to change the phrasing of the issue 4 (just audio/video)? -- due 2009-04-24 -- OPEN
<trackbot> http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/73
conrad, re issue no. 4?
<conrad> ok
ISSUE-9?
<trackbot> ISSUE-9 -- Should we have the media type inside the Test Cases? -- OPEN
<trackbot> http://www.w3.org/2008/WebVideo/Fragments/tracker/issues/9
<scribe> ACTION: Michael to flesh out TC vocabulary re ISSUE-9 [recorded in http://www.w3.org/2009/05/20-mediafrag-minutes.html#action03]
<trackbot> Created ACTION-82 - Flesh out TC vocabulary re ISSUE-9 [on Michael Hausenblas - due 2009-05-27].
<conrad> issue-4: so i think we discussed not predefining lots of track names, but perhaps predefining "audio" and "video" only: in which case action 73 would be to change issue 4 to "Should we predefine track names for audio and video"
<trackbot> ISSUE-4 Should we pre-define some track names? notes added
raphael: to push implementations
we need the proposals a bit better discussed
... all actions here continue
[adjourned]
<Gui> thanks, bye
<conrad> thanks all
silvia: good idea
just send an email to the list with subject [MF-TC] or so proposing it
I'll add it to the Wiki then, ok?
<silvia> cool
