And consider the ARIB liaison response. … TTML2 IR - I've had a look and would like to mention a couple of things … Lastly a small amount of TPAC planning. … Any other business, or points to ensure we cover? Pierre: Is that TTML2 issue on the agenda? Nigel: Not currently. Pierre: 1211 - the one about writingMode and direction … I guess if Cyril is not on the call maybe it will be a short discussion. Nigel: We can raise it. group: [no other business] IMSC 1.2 Rec Nigel: Congratulations all, and thank you all for your work on this, it's great to publish! … Special shout out to Pierre for Editing. [13]IMSC 1.2 Rec [13] https://www.w3.org/TR/ttml-imsc1.2/ Nigel: I think there is no more to do on this? Atsushi: I don't think there are any additional tasks for this Rec. Pierre: So Pull Request #563 should be merged? … And 565 good to merge too? Atsushi: Yes, that's in the Rec. Pierre: So all the outstanding Pulls should be merged? Atsushi: Please be careful not to conflict 564 and 565 Pierre: Yes, though the current ED is the Rec because there's no modification Atsushi: Right Pierre: Thank you, I will merge. Atsushi: 564 is the actual source file I used for publication. <atsushi> [14]https://github.com/w3c/imsc/pull/ 564#issuecomment-667834906 [14] https://github.com/w3c/imsc/pull/564#issuecomment-667834906 Pierre: I will be careful with that then … And in the Rec the group has been changed in the respec settings? Atsushi: No, the respec config is internal now, replacing the settings doesn't change the output. Pierre: Ok that's fine. But the Rec did not include pull 563 Atsushi: Yes, it does not include it, but it does include 565. Pierre: Alright, I will take care of that. I will merge 565 into 564 and then that will be the Rec, … and then separately will merge 563. Atsushi: sure. Pierre: OK I'll take of this, thanks. ARIB liaison response Nigel: Thank you to those who proposed changes on the google doc, they all made sense … so I accepted them all. … Just checking in, did anyone try to look at the google doc and fail? group: [silence] Nigel: Ok, a good sign. … I think this is good. There's one TODO on it, so we should do that and send. Pierre: There's some cleaning up, but I'm happy with the substance. Commas and full-stops … missing etc. Nigel: I will proof-read before sending. … For the TODO, I need to point them at somewhere for joining TTWG. … Could put me, or the home page, or the Charter. Is there a normal way to do it? Atsushi: Normally there would be a cover page, but for this time I think it is fine to include … the Charter/Home page and How to Join in that section of the response. Nigel: If I'm suggesting someone to talk to, should I mention the Chairs and yourself Atsushi? Atsushi: I suppose they will take the Chairs and team contact as myself from the liaisons page. Nigel: If ARIB members see this they are unlikely to know about the W3C liaisons page. … Better to be clear about how to join and who to talk to. … That's the Chairs and Team Contact I think. Good. Nigel: What review opportunities do we want? … By default, I think we're at the point where I can edit this and send it almost as is. … But if anyone wants more review time, please say! … I won't come to this until Monday at the earliest. Pierre: My recommendation is if you want to make the editorial pass, post it through the … reflector, give people 1 day and then proceed. Nigel: Thanks for that. … I think it's in the remit of the Chair to send this, and I really appreciate the input so far. … I will give a short review cycle and then proceed. … Thank you all! … We've spent a lot of time on this and I feel it is worthwhile. TTML 2 2nd Ed. Nigel: Last week I mentioned that the IR covers a lot of features, none of which are at risk. … I checked again and I think the structure of the IR doesn't quite match what the exit criteria … need. In particular there are changed features that have validation tests but no presentation … tests, and we may have presentation implementations that could usefully be brought in. … I'm thinking in particular about the implied audio features, where there is only a validation … test but there may be a presentation implementation. … Therefore I think we may need to restructure in relation the changed features and group … the tests like that instead of around validation pass/fail + presentation tests. … My thinking on that is work in progress. … I think the action for me is to follow up on this with Cyril and Glenn. Virtual TPAC 2020 planning Nigel: Thank you for your ongoing help organising, Atsushi. … Things are in progress with MEIG and Media WG, and with CSS WG. … However with CSS WG we don't have a list of agenda items, and I think it would be … helpful to begin putting that together if we can. … They may not be obvious, for example font fingerprinting could be one of them. Pierre: I think Cyril is key to this - he's recently filed an issue against Chrome for example. Nigel: I saw that, about oblique. Nigel: Then there's a request to us! … Janina from APA asked for a joint meeting about formalising synchronisation requirements … for making media accessible when there are different representations, e.g. text + audio. … That was my understanding. … I think we should say yes. We obviously do care about synchronisation of timed text … against media, and we don't know the shape of what they're proposing at this time. … Assuming there are no naysayers, I will respond positively. Gary: No objections here. … This goes hand in hand with what Chris Needham from BBC has been doing about the … timing of the cue events and time updates in the media element and how, because they … happen so infrequently, it's hard to synchronise. Nigel: Yes, I think it does. … I think one of the things APA is interested to know is if there are different thresholds for … synchronisation accuracy for different kinds of presentation. … This email was sent to me and Gary. I think she may not know about the links with … MEIG and Media WG, so we should respond to inform APA about that work. Nigel: I Chair ADCG too and asked them if they would like to spend time with us here, but … so far the silence implies they're happy for us to continue, I think. Nigel: Separately I think we have dates for the AC week in virtual TPAC 2020 now... … Thank you Atsushi for sending the details to the member-tt reflector. AOB - Chairing on 2020-08-13 Nigel: Regrets from me for next week. Assumption is the meeting goes ahead as normal? Gary: I can probably Chair it. Nigel: It doesn't seem that there's a huge amount for the agenda. Atsushi: do we plan long group meeting in solid date/time? Nigel: During TPAC? Atsushi: yes. 3 weeks of proposed meetings. … 1st joint. … 2nd group meetings. … 3rd breakouts … Do we plan to have our group meeting during TPAC? Nigel: I would be in favour - I think there are topics that could warrant a longer session. Pierre: Everybody is going to get the same slots so unless we need a WG meeting we should … avoid doing so. Nigel: I'm thinking about topics like IMSC future requirements, ADPT, TTML Live extensions … etc. and that will need a lot of prep. I think we could use a longer session, but it needs … prep time and it doesn't have to be in virtual TPAC, it could be later. Pierre: Exactly. Nigel: In answer, I think we quite likely won't meet, and if we do then it would likely be … maximum one day. Atsushi: We need to complete the wiki form, so if we can fix that it would be a great help … for me. Nigel: Understood! (AOB) Interaction between tts:writingMode and tts:direction on <p> w3c/ttml#1211 github: [15]https://github.com/w3c/ttml2/issues/1211 [15] https://github.com/w3c/ttml2/issues/1211 Nigel: One thing I note about this is Direction003 used to be in TTML tests and has moved … to IMSC tests and that has confused a couple of people independently recently. … Does anyone else feel that an explainer for Where to Find TTML Tests would be a useful document? Pierre: Looking at Glenn's comments, he thinks TTPE's presentation is wrong. Nigel: He thinks the reference render is wrong though. Pierre: [explains how the lines in the p all use the whole width so the layout direction - scribe failure] Nigel: Is textAlign used in the test? Pierre: It would be weird for textAlign to be affected by writingMode. … I think we need an answer from Glenn. Nigel: How do you know the line areas cover the whole width? That seems unusual. Pierre: Exactly. Pierre: Maybe we need to get everyone around the table for that with examples. Nigel: I'm sure if we schedule this for a meeting and invite Glenn then we can gather him and … anyone else interested. Andreas: I planned also to look into this issue so please keep me posted if you schedule a … separate meeting. Nigel: My default here would be to use one of these TTWG weekly calls if possible. Nigel: Let's allow the conversation to continue on the issue thread, and convene a meeting … perhaps in 2 weeks time, if there are outstanding questions. Pierre: Alright. SUMMARY: Continue discussions on the issue thread for the time being. Meeting close Nigel: The clock has just ticked over to the hour, and we've completed our agenda. I'm adjourning this meeting!
