5. ISSUES

close action-76

<trackbot> ACTION-76 Contact the editors of MPEG-21 Part 17 regarding the registry of their scheme closed

erik: not clear yet if MPEG fragment identifiers are registered

<mhausenblas> I'm looking at http://tools.ietf.org/html/rfc4288

section 4.11

<mhausenblas> Michael: really two issues here

<scribe> ACTION: Yves to find out more about fragment identifier registration [recorded in http://www.w3.org/2009/07/15-mediafrag-minutes.html#action02]

<trackbot> Created ACTION-89 - Find out more about fragment identifier registration [on Yves Lafon - due 2009-07-22].

<mhausenblas> Michael: one is re the SHOULD re frags in sec 4.11 of RFC4288

erik: status on a-62?

Yves: sent a mail to TAG, but no feedback yet

<mhausenblas> Michael: other is re registered image/*, video/* and audio/* - to me the answer here is: no, MPEG21 only has registered application/mp21 and hence we there is no clash

mhausenblas: A-82 is still ongoing
... this depends on reviewing and discussing the test cases

erik: resolutions for i-4 and i-10?
... no resolution yet on i-4, to be discussed further

<mhausenblas> Michael: re issue 10 the answer is easy

<mhausenblas> http://lists.w3.org/Archives/Public/public-media-fragment/2009May/0038.html

<Gui> We may need an action to resolve ISSUE-4.

<Gui> We should find what action ( or maybe a vote) is required at any next teleconf when Silvia is present

6. IMPLEMENTATION

erik: status?
... first work further on syntax and test cases?

<Gui> Yves has looked at libraries in Java

<Gui> Jack ( I think ) has looked at libraries in Python

Yves: looking for media slicing tools is part of the work, but do not depend on the syntax
... so we can start working on this kind of things
... not found a suitable non-transcoding media slicing tool

<Gui> Yves asks for help for implementation : how to slice the media without transcoding
