issue-401?
<trackbot> issue-401 -- Agent and actor circular references -- raised
<trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/401
nigel: I couldn't think of any semantic requiring the circular reference, so Glenn's proposal to prohibit the circular reference sounds reasonable to me.
close action-410
<trackbot> Closed action-410.
reopen issue-401
<trackbot> Re-opened issue-401.

<trackbot> issue-400 -- Make multiRowAlign and linePadding testfile EBU-TT-D compatible -- pending review
<trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/400
nigel: I resolved that issue

... We have the right people here to do that review. Frans,
Pierre?

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/406
nigel: Andreas updated me offline that there's no update on this so far.
action-409?
<trackbot> action-409 -- Nigel Megitt to Discuss liaison with unicode with richard ishida -- due 2015-07-09 -- OPEN
<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/409
nigel: There's been some activity
on this. I did send the new wording to Richard Ishida
... on Tuesday but he hasn't responded so far.
tmichel: I can ping Richard -
it's possible he's on vacation, but I can try. If we don't have
a response
... in a few days I think we can move on.
nigel: I wonder also if we could prompt Addison Phillips since Richard CCed him. I'm not sure what his role is.
tmichel: I'll check if they're on leave or if I can prompt them and let you know after the call.
nigel: Thanks.
issue-397?
<trackbot> issue-397 -- Sync recommended codepoints with CFF-TT -- pending review
<trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/397
pal: This is something that's
been on the to do list for a while. We were waiting for the
Unicode
... message to be ready before syncing with CFF-TT. There
haven't been many changes. Some
... of the Cyrillic scripts have had some code points added.
The proposed liaison to Unicode
... also contains the changed sets, so they should be identical
between CFF-TT, IMSC1 ED and the Unicode liaison message.
<inserted> nigel: They *should* be identical?
pal: Yes, ideally.
nigel: And you've checked that?
pal: Yes I did! I'm actually
working towards automating it but I'm not quite there yet so I
had
... to do a bit of manual work.
close issue-397
<trackbot> Closed issue-397.
nigel: Any more thoughts on the agenda?
pal: I really hope we'll be done
on IMSC 1 by then. I have a couple of people working on
... providing results to W3C, so I'm cautiously optimistic that
by late October we can move
... to PR. So then I think the topic might be what to do with
IMSC 2 and I suspect that will be
... a relevant topic at TPAC, so maybe we can add that to the
agenda?
nigel: Sure, sounds like a good idea.
pal: In particular, one of the
challenges that's been brought to my attention is that some
of
... the IMSC features don't have an exact (syntactic)
equivalent in TTML2 so that means that
... an IMSC 2 implementation also has to include an IMSC 1
implementation to parse some of
... those features. So that's a topic I suggest we should
discuss face to face.
nigel: Yes, makes sense.
pal: I understand there are
pluses and minuses and a lot of history. Purely from a user
standpoint
... without knowing the history it might cause a lot of
surprise to see that an IMSC 2 document
... uses different structures to achieve the same as IMSC 1.
Assuming that we're ready to move
... to IMSC 2 that would be a good time to have that
discussion.
nigel: You also need to understand if an IMSC 2 processor can process an IMSC 1 document.
pal: Yes. In other words the
current direction we're taking is one where an IMSC 1
document
... is not an IMSC 2 document (and cannot be). This is based on
the discussions so far.
nigel: Unless only the common set of features is used.
pal: Yes of course, yes. I think
this is worth discussion. In my mind this is intended to be
used
... so either we need a really good story or reason or change
plan or...
... We might even have incoming liaisons on this because there
are people interested in Ruby
... for example who are looking forward to IMSC 2. It's a topic
I think.
nigel: Agreed.
