14:07:54 <nigel> action-410?
14:07:54 <trackbot> action-410 -- Nigel Megitt to Raise issue regarding actor and agent references -- due 2015-08-06 -- PENDINGREVIEW
14:07:54 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/410

14:08:18 <nigel> issue-401?
14:08:18 <trackbot> issue-401 -- Agent and actor circular references -- raised
14:08:18 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/401
14:09:12 <nigel> 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.

14:09:28 <trackbot> Closed action-410.
14:09:33 <nigel> reopen issue-401

14:10:29 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/400
14:10:51 <nigel> nigel: I resolved that issue already - it's pending review.
14:11:33 <nigel> nigel: We have the right people here to do that review. Frans, Pierre?
14:11:44 <nigel> frans: Nigel, you spotted the error and fixed it already, so I think it's fine.
14:11:46 <nigel> pal: All good.
14:11:53 <nigel> close issue-400
14:11:53 <trackbot> Closed issue-400.
14:12:34 <nigel> action-406?
14:12:34 <trackbot> action-406 -- Andreas Tai to Follow on creating a strawman re: html cue extension specification -- due 2015-07-16 -- OPEN
14:12:34 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/406
14:12:45 <nigel> nigel: Andreas updated me offline that there's no update on this so far.

14:13:15 <trackbot> action-409 -- Nigel Megitt to Discuss liaison with unicode with richard ishida -- due 2015-07-09 -- OPEN
14:13:15 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/409
14:13:52 <nigel> nigel: There's been some activity on this. I did send the new wording to Richard Ishida
14:14:04 <nigel> ... on Tuesday but he hasn't responded so far.
14:15:24 <tmichel> ok move on ...
14:16:16 <nigel> tmichel: I can ping Richard - it's possible he's on vacation, but I can try. If we don't have a response
14:17:20 <nigel> ... in a few days I think we can move on.
14:18:09 <nigel> nigel: I wonder also if we could prompt Addison Phillips since Richard CCed him. I'm not sure what his role is.
14:18:24 <nigel> tmichel: I'll check if they're on leave or if I can prompt them and let you know after the call.
14:18:26 <nigel> nigel: Thanks.
14:18:46 <nigel> Topic: Issues
14:19:00 <nigel> issue-397?
14:19:00 <trackbot> issue-397 -- Sync recommended codepoints with CFF-TT -- pending review
14:19:00 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/397
14:19:40 <nigel> pal: This is something that's been on the to do list for a while. We were waiting for the Unicode
14:19:56 <nigel> ... message to be ready before syncing with CFF-TT. There haven't been many changes. Some
14:20:12 <nigel> ... of the Cyrillic scripts have had some code points added. The proposed liaison to Unicode
14:20:39 <nigel> ... also contains the changed sets, so they should be identical between CFF-TT, IMSC1 ED and the Unicode liaison message.
14:20:50 <nigel> pal: Yes, ideally.
14:20:54 <nigel> nigel: And you've checked that?
14:21:11 <nigel> pal: Yes I did! I'm actually working towards automating it but I'm not quite there yet so I had
14:21:16 <nigel> ... to do a bit of manual work.
14:21:54 <nigel> close issue-397
14:21:54 <trackbot> Closed issue-397.
14:22:46 <nigel> Topic: TPAC 2015
14:22:50 <nigel> nigel: Any more thoughts on the agenda?
14:23:04 <nigel> pal: I really hope we'll be done on IMSC 1 by then. I have a couple of people working on
14:23:17 <nigel> ... providing results to W3C, so I'm cautiously optimistic that by late October we can move
14:23:34 <nigel> ... to PR. So then I think the topic might be what to do with IMSC 2 and I suspect that will be
14:23:48 <nigel> ... a relevant topic at TPAC, so maybe we can add that to the agenda?
14:23:52 <nigel> nigel: Sure, sounds like a good idea.
14:24:04 <nigel> pal: In particular, one of the challenges that's been brought to my attention is that some of
14:24:18 <nigel> ... the IMSC features don't have an exact (syntactic) equivalent in TTML2 so that means that
14:24:30 <nigel> ... an IMSC 2 implementation also has to include an IMSC 1 implementation to parse some of
14:24:42 <nigel> ... those features. So that's a topic I suggest we should discuss face to face.
14:24:52 <nigel> nigel: Yes, makes sense.
14:25:07 <nigel> pal: I understand there are pluses and minuses and a lot of history. Purely from a user standpoint
14:25:21 <nigel> ... without knowing the history it might cause a lot of surprise to see that an IMSC 2 document
14:25:34 <nigel> ... uses different structures to achieve the same as IMSC 1. Assuming that we're ready to move
14:25:43 <nigel> ... to IMSC 2 that would be a good time to have that discussion.
14:26:13 <nigel> nigel: You also need to understand if an IMSC 2 processor can process an IMSC 1 document.
14:26:28 <nigel> pal: Yes. In other words the current direction we're taking is one where an IMSC 1 document
14:26:55 <nigel> ... is not an IMSC 2 document (and cannot be). This is based on the discussions so far.
14:27:05 <nigel> nigel: Unless only the common set of features is used.
14:27:19 <nigel> pal: Yes of course, yes. I think this is worth discussion. In my mind this is intended to be used
14:27:33 <nigel> ... so either we need a really good story or reason or change plan or...
14:27:49 <nigel> ... We might even have incoming liaisons on this because there are people interested in Ruby
14:28:00 <nigel> ... for example who are looking forward to IMSC 2. It's a topic I think.
14:28:02 <nigel> nigel: Agreed.
14:28:30 <nigel> Action: nigel Add draft topics for TPAC to wiki page as discussed today and last week
14:28:30 <trackbot> Created ACTION-412 - Add draft topics for tpac to wiki page as discussed today and last week [on Nigel Megitt - due 2015-08-13].
