15:06:19 <nigel> Nigel: Light agenda today - TTML2, TPAC and TTML Profiles Registry
15:06:33 <nigel> .. Any points to make sure we cover, or any other business?
15:06:35 <mike> mike has joined #tt
15:06:57 <nigel> group: [no other business]
15:07:08 <nigel> Topic: TTML2 2nd Edition
15:07:28 <nigel> Nigel: I noticed a change to the IR recently, by Glenn. Any other discussion points on this?
15:08:25 <nigel> .. We have a placeholder for ttml2#1211 if anyone has anything to raise?
15:08:34 <nigel> group: [no points to discuss on that at this time]
15:08:47 <nigel> Topic: Virtual TPAC 2020 Planning
15:08:57 <nigel> Nigel: I think we're good in terms of meeting times.
15:09:04 <nigel> .. And I see TPAC registration is now open.

15:10:00 <nigel> -> https://www.w3.org/2020/10/TPAC/ TPAC 2020 public page
15:10:09 <nigel> Nigel: Please do register!
15:10:23 <nigel> .. It's free this year.
15:11:11 <nigel> .. Any queries about any of our joint meetings?
15:11:21 <nigel> group: [no queries]
15:11:37 <nigel> Topic: TTML Profiles Registry
15:11:58 <nigel> Nigel: I merged the open pull request yesterday so our favourite perennial #71 is now closed.
15:12:42 <nigel> Mike: I haven't opened the PR for #76 yet but I will.
15:13:10 <nigel> Nigel: And the other open issue is for the reference to TTML 1, which cites 2nd Ed instead of 3rd Ed.
15:13:25 <nigel> Mike: I think that's editorial.
15:13:35 <nigel> Nigel: Formally, I'm not sure if it's editorial, but the change is the right thing to do anyway.
15:14:12 <nigel> Cyril: Piece of information on the profile registry. ISO BMFF part 12, 6th Edition should get
15:14:24 <nigel> .. published soon. When it gets published, it now defines the codecs parameter, so you
15:14:39 <nigel> .. should expect a change to RFC6381, so I don't know if this will impact our registry.
15:15:08 <nigel> Nigel: Will part 12 be publicly available at no cost?
15:15:09 <nigel> Cyril: Yes
15:15:26 <nigel> .. But the base syntax for codecs is not moving, only the meaning of the parameter in
15:15:49 <nigel> .. the context of MP4. It's only the note about where the codecs parameter is defined for MP4
15:15:56 <nigel> .. that might change.
15:16:00 <nigel> .. I don't think it's a big deal.
15:16:14 <nigel> Nigel: So to clarify, the syntax reference to the RFC will not need to change?
15:16:18 <nigel> Cyril: I don't think so.
15:16:24 <nigel> Nigel: Thanks, that's good information.
15:16:55 <nigel> Cyril: One other thing - the status of the registry says Editor's Draft. Is there another
15:16:58 <nigel> .. type of document we could use?
15:17:07 <nigel> Nigel: The one on TR?
15:17:13 <nigel> Cyril: No, the TR one is WG Note.
15:17:17 <nigel> Nigel: That's what I expect
15:17:25 <nigel> Cyril: So we expect to update the TR version?
15:17:37 <nigel> Nigel: Yes, the only formal process is we need to resolve to do it.
15:17:44 <nigel> Atsushi: Yes we just need WG consensus.
15:18:59 <nigel> Nigel: I think we should aim to do that as soon as we can, practically.
15:19:16 <nigel> .. I'm not sure what people think of publishing every time a pull request gets changed?
15:19:45 <nigel> .. The lag between e.g. adding the 4cc for IMSC 1.2 and publishing is something I would like to redue.
15:19:50 <nigel> s/redue/reduce
15:19:51 <atsushi> https://www.w3.org/TR/clreq/
15:20:01 <nigel> Cyril: Can we point TR at the ED?
15:20:11 <nigel> Atsushi: No, we can publish a WG Note Draft like the link above.
15:20:32 <nigel> .. It is updated on the 1st day of every month, by copying from the ED
15:21:14 <nigel> Nigel: I'm not sure if it helps to have another version of the document that is not the official one.
15:21:22 <nigel> Atsushi: It's just for information, this option is available.
15:21:31 <nigel> Nigel: I understand.
15:22:28 <nigel> Nigel: How do you feel about the idea of publishing a WG Note every time we merge a pull
15:22:32 <nigel> .. request into the ED?
15:22:50 <nigel> Cyril: I think it's a good idea
15:23:04 <nigel> Nigel: If we wanted to do that, what would we have to do to make it happen?
15:23:22 <nigel> Atsushi: There's no requirement, so we can just record the CfC here.
15:23:40 <nigel> Nigel: I meant mechanically, can we trigger an action to update TR
15:23:56 <nigel> Atsushi: No, someone would have to trigger echidna, but a link to the resolution of consensus
15:23:59 <nigel> .. is required to run it.
15:24:41 <nigel> Nigel: I think I'm arguing that we have enough process in the WG that agreeing to merge
15:24:53 <nigel> .. the pull request into gh-pages counts as consensus, but I can see there's risk associated
15:24:58 <nigel> .. with this approach as well.
15:25:24 <nigel> .. Anyway right now I think we should be aiming to get these last two issues resolved as
15:25:30 <nigel> .. soon as we can and then resolve to publish.
15:26:18 <nigel> Topic: Meeting close
15:26:27 <nigel> Nigel: We've completed our agenda. Thank you everyone. [adjourns meeting]
