3. Specification

Yves: will do my action in the next 2 weeks

<Zakim> mhausenblas, you wanted to comment on structure of the WD

Erik: regarding action-67, I will provide an example

Michael: I want to talk about action-64
... I want to change the structure of this sub-section, this is the processing model
... and discuss what's happen on the UA side, and on the server side

Raphael: +1 for Michael's suggestion for the next iteration of the WD

<silvia> so the suggestion is to rename 6.4 to Processing?

<erik> +1 for next iteration

<mhausenblas> 6.4 -> Interpretation and Processing of MF

<silvia> good, like it

Michael: but not talk about semantics

<mhausenblas> 6.4.1 Overview

+1

<mhausenblas> 6.4.2 UA view

<mhausenblas> 6.4.3 Server

<silvia> +1

Conrad: I hope to complete my actions 63 and 69 later this week

4. Test Cases

<mhausenblas> http://www.w3.org/2008/WebVideo/Fragments/wiki/TestCasesOverview

Actual test cases: http://www.w3.org/2008/WebVideo/Fragments/wiki/TestCases

Michael: I motivated first the need for test cases
... I then provided examples of test cases, these need to be approved

<mhausenblas> TC setup

Email and issues from Michael: http://lists.w3.org/Archives/Public/public-media-fragment/2009Apr/0135.html

Raphael: no value means by default for the temporal dimension the start time (end time) of the resource

Yves: empty is different than not present ... i.e. sometimes, the dimension is not present, sometimes we have the default value

Michael: please, review the Test Cases, edit the wiki, mail the mailing list
... the intention is to go away from the wiki asap
... since it is really painful

5. Issues

<trackbot> http://www.w3.org/2008/WebVideo/Fragments/tracker/issues/4

<mhausenblas> http://www.w3.org/2008/WebVideo/Fragments/wiki/UserAgentMediaFragmentResolution

Raphael: I have finally understood this issue, this is the UA point of view of what's hapening

Michael: regarding the step 2
... I'm referring to Common User Agent Problems

<Yves> foo#bar in a redirect is currently not allowed

Michael: I just write the various possibilities
... perhaps we should just have the default behavior fallback, stating that the UA should write valid MF URI

<scribe> ACTION: Yves to investigate what's happened when facing an invalid Media Fragment URI, re step 2 of http://www.w3.org/2008/WebVideo/Fragments/wiki/UserAgentMediaFragmentResolution [recorded in http://www.w3.org/2009/04/29-mediafrag-minutes.html#action02]

<silvia> ok, understood :)

Michael: I will put this description and diagram in the document ... instead of semantics -> processing of the media fragments

ISSUE-8?

<trackbot> ISSUE-8 -- Missing collection of MF WG decisions -- OPEN

<trackbot> http://www.w3.org/2008/WebVideo/Fragments/tracker/issues/8

Do we want a wiki page that centralizes all the resolution?

Silvia: I think the issues page barely captures that

Michael: I don't think so

Silvia: the page captures our discussion, but I agree does not endorse the decision

Michael: can we misuse the tracker?

We have resolved all the polls

Michael: I volunteer to maintain this page if chairs create it

trackbot, status?
