Hmm .. that makes it a bit more difficult for me to attend. I will try

Thanks,
Silvia.

>> 2. USE CASES & REQUIREMENTS
>>
>> * ACTION-156: Conrad to add a "bandwidth conservation use case"
>>
>> 3. SPECIFICATION:
>>
>> 3.1 Media Fragment URI syntax: (Yves)
>>
>> * ACTION-151: Yves to modify the production rule for the track dimension
>> in order to allow multiple semi-colon separated values
>> * ACTION-152: Yves to change the formal syntax to reflect that we don't
>> need a subdelim for selecting multiple tracks but we allow multiple
>> track= in the URI
>> * ACTION-153: Raphael to review the complete document and check whether
>> there are more references to uniqueness
>>
>> 3.2 Protocol for URI fragment Resolution in HTTP:
>> * ACTION-123: Yves to come up with ABNF for header syntax
>> * ACTION-154: Yves to add a section 5.2.4 describing his new optimization
>> * ACTION-137: Jack to check that 5.1 is implementable using the protocol
>> * ACTION-155: Davy to draw diagrams to include in the spec, similar to
>> Yves's email, that shows which bytes from the headers and body of the
>> media file are sent
>>
>> 3.3 Rendering of Media Fragments URI in UA:
>> * ACTION-135: Davy, Erik to extend section 7 regarding spatial and track
>> dimension
>> * ISSUE-5 [Jack]: Handling spatial cropping requires information at
>> client-side
>>
>> 3.4 Discovery of 'Track' and 'Named' fragments:
>> * ISSUE-4 [Silvia]: Should we pre-define some track names?
>> * Davy's strawman implementation using ROE:
>>
>> http://lists.w3.org/Archives/Public/public-media-fragment/2009Nov/0014.html
>> * Silvia's blog post:
>>
>> http://blog.gingertech.net/2009/11/25/manifests-exposing-structure-of-a-composite-media-resource/
>>
>> * Jack's proposal to write up that we should distinguish the mechanism

>> * Corrib test tool: http://ld2sd.deri.org/corrib/
>> * ACTION-146: Jack to identify and add in corrib any missing test cases
>> for temporal fragments
>> * ACTION-158: Raphael to enter the big table of all test cases for the
>> temporal dimension in the wiki
>> * ACTION-147: Michael to add all MF WG members to corrib
>> * ACTION-148: Michael to add a copy TC functionality in corrib
>> * ACTION-149: Michael to come up with a fix for overview vs. edit single
>> TC in corrib
>> * Suggestion of nasty test cases by Philip:
>>
>> http://lists.w3.org/Archives/Public/public-media-fragment/2009Dec/0015.html
>>
>> 5. ISSUES
>>
>> 5.1 Active:
>>
>> 5.2 Non-Active:
>> * ISSUE-6 [Jack]: Temporal clips that require transcoding
>> * ISSUE-7 [Michael]: User Agent Media Fragment Resolution and Processing
>> * ISSUE-9 [Michael]: Should we have the media type inside the Test Cases?
>> * ISSUE-12 [Raphael]: What's the relationship between Images (CSS)
>> Sprites and the spatial dimension of the Media Fragments URI scheme?
>> * ISSUE-13 [Raphael]: Write a IETF draft for proposing how to register
>> the fragment scheme for all media types
>> * ISSUE-14 [Davy]: How to deal with embedded time stamps
>> * ISSUE-16 [Jack]: Combining axis is probably not going to be done by
>> LC, but we should write somewhere that this is doable
>>
>> 6. IMPLEMENTATION:
>> * ACTION-34: Jack to look at python-url library to see whether he could
>> implement the logic on client side
>> * ACTION-35: Raphael to look at curl and/or wget to see whether the
>> logic could be implemented on client side
>> * ACTION-70: Jack to commit in CVS (code directory) his python code
>> doing the parsing on client side of the media fragment

>> Javascript that does the client-side media fragments parsing?
