Issues discussed and raised over the past week
issue-307?
<trackbot> issue-307 -- Conformance language and processor
profile rather than content profile. -- raised
<trackbot>
[13]http://www.w3.org/AudioVideo/TT/tracker/issues/307
[13] http://www.w3.org/AudioVideo/TT/tracker/issues/307
pal: I've added a note to the issue. I agree re language use
and consistency.
... IMSC is primarily a content profile.
nigel: I'm concerned with using the term profile for content
profile when it's defined as 'processor profile' in TTML1. We
know what 'content profile' means informally but it's defined
in TTML1 as a processor profile.
pal: I can amend to be explicit about content profiles too.
nigel: We should also make sure that content profile language
is aligned in TTML2 with what we want to use in IMSC
pal: One proposal is to use 'content profile'. In practice
everybody will use 'profile' so that will make the wording more
verbose.
... Can we wait for Glenn's advice before making edits?
nigel: yes, happy with that.
OPEN issue-307
s/
pal: another term that is used in SDP-US is "document profile",
which is fairly close to what IMSC uses today.
nigel: that makes sense too.
... have opened the issue.
issue-308?
<trackbot> issue-308 -- It is unclear how a document is
associated with a related video object -- raised
<trackbot>
[14]http://www.w3.org/AudioVideo/TT/tracker/issues/308
[14] http://www.w3.org/AudioVideo/TT/tracker/issues/308
pal: Related video object should be replaced with Related Media
Object everywhere.
... There's no constraint on related objects unless
ttp:frameRate is specified
... If you want the document to be independent of video frame
rate don't use times with frames.
nigel: This is an editorial issue on ยง4.4 3rd paragraph: I
think what is meant is that if time expressions with frames are
used then the frame rate in the related video object must be
the same as that set.
pal: In fact if frames are to be used then ttp:frameRate must
be set in IMSC so they are equivalent, but I can add a note to
make this clearer.
... I've added a note to the issue.
... I plan to wait for more comments, e.g. until the 3rd week
of May, and look at the comments received then before updating
the document.
Change Proposals

jdsmith: We need Glenn before closing this.
nigel: It would be helpful to have advance notice of any CPs
that we plan to work on.
jdsmith: I've reviewed internally and can discuss these on the
agenda next week - the CPs I own.
nigel: Thank you, I'll add them to the agenda.
