> 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-compos
> ite-media-resource/
> 
> * Jack's proposal to write up that we should distinguish the mechanism
> (ROE, MPEG-21) vs the semantics
> 
> 4. TEST CASES: (Michael)
> * 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:
>

> * 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
> * Someone to investigate whether he could have an implementation in
> Javascript that does the client-side media fragments parsing?
