* Roll call
* PROPOSED to accept the minutes of the 02 December 2009 telecon:
* Next F2F Meeting: see 
* ACTION-92: Erik and Raphael to coordinate the writing of papers (ongoing
... re-raise around 15/01/10)

* Discuss the 2 documents for publication (see Silvia's great work :)
** Go through changes:


ACTION: discuss & get resolution to publish (as is)
** Close actions 123, 124, 125?

2.1 Media Fragment URI syntax: (Yves)
* Bug in the npt specification found by Philip:

"I'd also like to point out that the ABNF for NPT does not match
RFC2326. It allows there to be 0 or more digits following the decimal
point, while the MF ABNF allows 1 or more digits."

ACTION to take?

2.2 UA Server HTTP Communication: (Conrad/Raphael)
* ACTION-123: Yves to come up with ABNF for header syntax

restructuration plan (see also 2.0)

2.3 Media Fragment Processing:
* Question of MF URI validity by Philip:
* Suggestion of nasty test cases by Philip:

2.4 Discovery of 'Track' and 'Named' fragments:
* ISSUE-4 [Silvia]: Should we pre-define some track names?
* Davy's strawman implementation using ROE:
* Silvia's blog post:
* Jack's proposal to write up that we should distinguish the mechanism (ROE,
MPEG-21) vs the semantics

3.5 Handling of 'Track' and 'ID':
Conrad's proposal (Fragment header):

4. TEST CASES: (Michael)
* Corrib test tool: http://ld2sd.deri.org/corrib/ 
* ACTION-108: Michael to add the missing test cases in corrib
* ACTION-115: Michael to come up with categorization of test cases wrt
empty, undefined, etc
* ACTION-118: Michael to come up with individual 'normal' test cases (+/-
* ACTION-119: Yves to request admins to set up a cvs notifications mailing
list and notifications

* 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
* ACTION-71: Michael to investigate whether he could have an implementation
in Javascript that does the client-side media fragments parsing
