Topic: this meeting
15:08:08 [cyril]
nigel: some imsc topics, and TTML2 IR, and tests
15:08:20 [cyril]
... there is one AOB which is planning for TPAC
15:08:37 [cyril]
... is there any other business ?
15:08:50 [cyril]
... I noticed a open PR with a stalled discussion
15:09:28 [cyril]
[silence]
15:09:45 [cyril]
Topic: IMSC1.2
15:10:08 [cyril]
nigel: we seem to have a way forward to have the rec link fixed on the published spec
15:10:21 [cyril]
atsushi: last week we discussed editing the spec
15:10:31 [cyril]
... but that was invalid
15:10:41 [cyril]
... the only way is to do in place editing
15:10:49 [cyril]
... simply editing the HTML not using respec
15:11:19 [cyril]
nigel: that's ok we just need to make sure in respec that future editions will have the correct spec
15:11:46 [cyril]
nigel: any other thoughts?
15:11:50 [cyril]
pal: sounds good
15:12:12 [cyril]
pal: very quickly on IMSC1.2
15:12:26 [cyril]
... HR still no feedback on 2 PR from the APA?
15:12:36 [cyril]
nigel: I had an action to ping Michael Cooper
15:12:46 [cyril]
... he responded to my email saying he'd look at it
15:12:51 [cyril]
... but so far hasn't
15:12:57 [cyril]
pal: this is frustrating
15:13:07 [cyril]
... we were responsive in responding to their comments
15:13:20 [cyril]
nigel: I had his response on April 8th
15:13:25 [cyril]
... over a week now
15:14:54 [cyril]
nigel: the earliest date to advance to PR is the 5th of May
15:15:21 [cyril]
... but we need a version integrating comments
15:15:26 [cyril]
... I should nag them
15:15:30 [cyril]
... this is critical path
15:16:23 [cyril]
cyril: if it were a non HR comment, we would have closed the comment already
15:16:36 [cyril]
pal: we should include the team in the email thread
15:17:32 [cyril]
Topic: TTML2 2nd Edition Implementation Report - tests
15:17:58 [cyril]
nigel: we have 2 open PRs
15:19:23 [cyril]
... those PRs are againts 2 open issues on TTML2 test
15:20:19 [cyril]
glenn: I just updated PR 252 this morning to add the line breaks as you had requested
15:20:29 [cyril]
... if you are satisfied we can dispatch it
15:20:31 [cyril]
nigel: I will
15:20:37 [cyril]
... have a look
15:21:05 [cyril]
glenn: the other one, I'll run through the issues next day or so
15:21:17 [cyril]
... I need to make a run on the IR document
15:21:34 [cyril]
... still don't know if anybody is working on actual implementation other than BBC on audio
15:22:05 [cyril]
nigel: as far as audio and BBC, we integrated it to our tests and it succeeds
15:22:26 [cyril]
... it's public and visible so I'll add a link in the IR
15:23:03 [cyril]
cyril: Netflix will have a very limited report regarding the new tests
15:23:16 [cyril]
glenn: at least we'll have an implementation by the end of April
15:23:20 [nigel]
-> https://www.w3.org/wiki/TimedText/TTML2SecondEditionImplementationReport TTML2 Second Edition Implementation Report
15:23:29 [cyril]
... for all the presentation tests and validation tests
15:23:50 [cyril]
... I'll have to coordinate with Cyril with what they can provide and then see what's missing
15:24:13 [cyril]
cyril: I suspect we will be missing a second validation implementation only
15:24:32 [cyril]
glenn: correct. previously we had other validation implementations, from Pierre and Andreas
15:24:58 [cyril]
... in this particular set of tests, it's a mixture of presentation tests and validation tests
15:25:07 [cyril]
... 50/50
15:25:38 [cyril]
nigel: the current IR does not need much change
15:25:56 [cyril]
... quite a few, maybe 50 validation tests, and 20-25 invalid, 3 presentation tests
15:26:05 [cyril]
... I know more presentation tests need to be added
15:27:11 [nigel]
s/does not need much change/needs a review because I know some tests are missing. There are
15:27:15 [nigel]
s/50/15
15:27:54 [cyril]
nigel: anything else on that agenda topic?
15:28:02 [cyril]
[silence]
15:28:24 [cyril]
glenn: there are TTML2 editorial issues (typos)
15:28:33 [cyril]
... you had a request to make a change to an example
15:28:41 [cyril]
... I don't like to do it in 2nd edition
15:28:53 [cyril]
... I'd prefer to delay it to 3rd ed
15:29:03 [cyril]
nigel: I already did a PR for a typo fix
15:29:12 [cyril]
... for the other one, I did not understand the concern
15:29:24 [cyril]
... I suggested changing 2 lines in the example
15:29:36 [cyril]
... you made a comment that they have been stable since TTML1
15:29:56 [cyril]
glenn: we are only on record that the only changes that we would do are typo changes
15:29:58 [cyril]
... this is not
15:30:12 [cyril]
... this is not a WR or HR either
15:30:46 [cyril]
nigel: I would consider it HR as it is completely editorial
15:31:02 [cyril]
... not a big deal, but clearly caused confusion
15:31:25 [cyril]
glenn: it wasn't part of the review before CR
15:31:34 [cyril]
nigel: I just received the feedback
15:32:02 [cyril]
... I'll continue to prepare the change regardless of when we merge it
15:32:21 [cyril]
... people were taking the example in the introduction as a good practice for positioning
15:33:46 [cyril]
... it seemed to me that it was worthwhile to address that feedback
15:34:29 [cyril]
glenn: you said that if you have a body that specifies a region and an children with another region, some content would disappear
15:34:35 [cyril]
nigel: yes, it gets pruned
15:34:46 [cyril]
... we had a long discussion in the past and concluded that
15:34:55 [cyril]
glenn: hmm... I believe you are right
15:35:04 [cyril]
nigel: that's why I think it's a bad example
15:35:20 [cyril]
glenn: it's not applicable to the actual example
15:35:45 [cyril]
... that could be resolved by adding a note to the example
15:35:55 [cyril]
nigel: why not
15:36:21 [cyril]
glenn: I would be amenable to adding a note now
15:36:29 [cyril]
nigel: let me have a look
15:36:43 [cyril]
glenn: I just don't want to change the example
15:37:25 [cyril]
Topic: TPAC Planning
15:37:38 [cyril]
nigel: you might have seen TTWG issue 112
15:37:53 [cyril]
... staff have sent chairs a link to a survey
15:37:58 [cyril]
... as usual
15:38:22 [cyril]
... obviously this year is weird
15:38:29 [cyril]
... not clear we will have a physical meeting
15:38:40 [cyril]
... they have added questions about a virtual meeting
15:38:55 [cyril]
... not sure the best way is to have the discussion now
15:39:09 [cyril]
... so please have a look
15:39:14 [nigel]
github: https://github.com/w3c/ttwg/issues/112
15:39:31 [cyril]
nigel: the virtual meeting questions are
15:39:53 [cyril]
... general attitude towards having it (too complicated, ...)
15:41:19 [cyril]
atsushi: W3C opened several pages of notes for operations under the current situation
15:41:41 [nigel]
-> https://www.w3.org/Guide/meetings/continuity.html Continuity of Operations under Travel Restrictions
15:41:44 [cyril]
... for this past one month, there were several F2F 3-4 meetings per day over 1 week
15:42:03 [atai]
q+
15:42:03 [cyril]
... short meetings is considered an alternative meeting for offline TPAC
15:42:28 [cyril]
... it might be possible to have TPAC over several weeks
15:42:46 [cyril]
.. there are several discussions, no solid decision to have online or offline
15:43:15 [cyril]
pal: I want to echo that trying to recreate TPAC virtually is a fool's errands
15:43:18 [atsushi]
continuity of operations under travel restrictions -> https://w3c.github.io/Guide/meetings/continuity.html
15:43:27 [cyril]
... virtual meetings have to be planned differently
15:43:50 [cyril]
... on the other hands, having a time and place to bring together multiple threads is very valuable
15:43:57 [cyril]
... on many weeks or one week
15:44:02 [cyril]
... is a good idea

15:46:46 [nigel]
.. at something like 0500, 1000 and 2000 UTC time.
15:47:00 [nigel]
.. I think we should avoid trying to do something like that.
15:47:04 [nigel]

15:47:24 [nigel]
Andreas: I agree. It's worthwhile thinking about the goals of TPAC and trying to
15:47:33 [nigel]
.. achieve the same goals virtually in whatever form.
15:47:46 [nigel]
.. It's a good opportunity to say that what is special about TPAC is not WG meetings,
15:47:57 [nigel]
.. but joint meetings, because every group is organised in the same place.
15:48:11 [nigel]
.. It would be a good idea to meet maybe over several weeks in fixed time zones over 2-3
15:48:21 [nigel]
.. hours, with short WG meetings for preparation and post-joint-meeting discussions.
15:48:36 [nigel]
.. It will be good to wait until the May AC meeting experience, which will also be virtual.

15:49:20 [cyril]
s/XXXXX/I'm the best/
15:49:35 [nigel]
.. It should be focused on joint work and I don't think that individual groups should
15:49:47 [nigel]
.. be encouraged to meet. My observation is that virtual meetings can be more efficient
15:49:52 [nigel]
.. but require a lot more pre-planning.

15:51:00 [nigel]
Pierre: When meeting face to face sometimes people take shortcuts, and it is easier
15:51:10 [nigel]
.. to have side conversations. Maybe people feel they've set aside the time so they can
15:51:17 [nigel]
.. fill it more flexibly. It's hard to tell.
15:51:27 [nigel]
.. I like the idea of a TPAC where common threads are brought together but please
15:51:33 [nigel]
.. let's not schedule WG meetings during that week,

Atsushi: Just for info about the AC meeting next month.
15:52:02 [nigel]
.. It is quite different from WG discussions so W3C will provide pre-recorded videos
15:52:18 [nigel]
.. for talks over 9-10 hours and try to have 90 minute conversations, two times.
15:52:27 [nigel]
.. That's how virtual AC 2020 will be organised.
15:52:51 [nigel]
.. It's quite a different set of conditions from our WG meeting.

15:55:08 [nigel]
Nigel: Would it be a good idea to try to simulate side-conversations?
15:55:17 [nigel]
Pierre: If anyone can crack that it would be great progress for humanity in general!
15:55:30 [nigel]
.. If there's a way to solve it that would be great. Current platforms make it really
15:55:33 [nigel]
.. hard to have those conversations.
15:55:52 [nigel]
.. Those side conversations only happen during meetings, and it isn't facilitated in breaks etc.
15:55:59 [nigel]
.. If any org can do it, W3C can!
15:56:09 [nigel]
.. It is the missing thing from virtual meetings.
15:56:21 [nigel]
.. People work around it somehow. Maybe it can be integrated in meeting planning.
15:56:34 [nigel]
.. That's a stretch goal. It is possible to plan TPAC as a virtual meeting, but will require
15:56:37 [nigel]
.. more planning than usual.
15:57:39 [nigel]
Nigel: Another question is on the duration and timezone. A single TPAC timezone,
15:57:51 [nigel]
.. or using only a small part of the working day that works best globally?
15:58:23 [nigel]
Pierre: I would be pragmatic here for a big plenary. For joint meetings, base it entirely
15:58:33 [nigel]
.. on the membership, and who can attend and where they are.
15:58:57 [nigel]
.. Picking a single time zone is not pragmatic. It is simple conceptually but makes nobody
15:59:07 [nigel]
.. happy other than the people in that timezone. I don't like that solution at all.
15:59:40 [nigel]
Glenn: Was there a location originally planned?
15:59:43 [nigel]
Nigel: Vancouver
15:59:55 [nigel]
Pierre: I'd love it in Vancouver's time zone but I think it's a terrible idea.
16:00:49 [nigel]
.. For individual group meetings I would base it entirely on the attendees.
16:00:57 [nigel]
q?
16:02:07 [nigel]
Nigel: We are out of time for today and we covered a lot, but we may need to come back to canvas
16:02:17 [nigel]
.. opinions on some of the questions we haven't tackled.
16:02:33 [nigel]
Gary: One idea for the side conversation is time scheduled for a Webex where anyone
16:02:47 [nigel]
.. can join, regardless of group, especially if we are doing the remote thing.
16:02:55 [nigel]
.. Some people may still have travel restrictions in place.
16:04:32 [nigel]
SUMMARY: Initial discussion: don't try to reproduce TPAC virtually, focus on the joint meetings and main benefits of cross-fertilisation of ideas and groups.
