1. ADMIN:
* Roll call
* PROPOSED to accept the minutes of the 14 April 2010 telecon:
http://www.w3.org/2010/04/14-mediafrag-minutes.html
* ACTION-119: Yves to request admins to set up a cvs notifications 
mailing list and notifications
* ACTION-92: Erik and Raphael to coordinate the writing of papers
** Postpone (new deadline is May 1st 2010)
* Next WG F2F: http://www.doodle.com/rt7fsz583hgzrcki
** Proposal: F2F meeting organized on 15-16 June in EURECOM/Sophia 
Antipolis by Yves and I

2. USE CASES & REQUIREMENTS

* ACTION-156: Conrad to add a "bandwidth conservation use case"

3. SPECIFICATION:

[close ACTION-159]

3.1 Media Fragment URI syntax: (Yves)

* 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

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-160: Yves to send an email reporting the issue for track names
* ACTION-137: Jack to check that 5.1 is implementable using the protocol

3.3 Rendering of Media Fragments URI in UA:
* 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 
(ROE, MPEG-21) vs the semantics

4. TEST CASES: (Michael)
* Corrib test tool: http://ld2sd.deri.org/corrib/
* ACTION-161: Silvia to integrate the test cases into the spec
* ACTION-146: Jack to identify and add in corrib any missing test cases 
for temporal fragments 	
* 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
* Someone to investigate whether he could have an implementation in 
Javascript that does the client-side media fragments parsing?
