Hi all,

Apologies again for not being able to make the conference call. A
later time (about 2 hours later) would actually work better for me

I have some comments inside the minutes...

2009/3/25 RaphaŽl Troncy <Raphael.Troncy@cwi.nl>:

OK, I have now added the remaining "Required types of media fragments"
section and with this the use cases and requirements section should be

I agree with removing formal grammar. There's also a bit in the CMML section.

I disagree - I think this section should get slightly extended with a
description of how each of these schemes works. They explain our

5.1 and 5.3 are not identical - a lot of the 5.1 specs are not repeated in 5.3

I have a problem with CMML - CMML is not the temporal URI spec.
I think that section needs to be split into the temporal URI spec here
in and a CMML section in a new 5.3.3 section on "Named

We are also missing a "Track Fragments" section with examples where
that is already possible (if they exist).

I also offer to work over the "CMML" section and make it more
appropriate for the document.

Ogg does not need to be sliced - there are server extensions that do
that for you dynamically. I would suggest to install oggz-chop and the
cgi on the Web server if we can. Yves - would that be possible?

I sure would love to see that! Can you maybe do a screencast?
