Any other topics? 14:07:51 glenn has joined #tt 14:07:52 tmichel has joined #tt 14:07:54 Present+ Mike 14:08:53 nigel: One AOB from me is next f2f planning 14:09:03 Topic: Profiles Registry 14:09:15 nigel: One new issue: https://github.com/w3c/tt-profile-registry/issues/26 14:09:57 nigel: The IANA registration has been updated in place. There's an RFC change issue as above. 14:10:13 Present+ Thierry 14:10:33 mike: This does not impact us technically, it's more a housekeeping thing. At the moment 14:10:47 ... our document says one thing and the IANA one says another so that seems reason to 14:10:52 ... update it. 14:10:55 nigel: I think so, yes. 14:11:37 nigel: Thierry has already made the pull request: https://github.com/w3c/tt-profile-registry/pull/27 14:12:39 tmichel: I did this - there were 2 occurrences of this RFC to fix. 14:13:12 mike: I haven't looked at what was done yet. 14:13:23 tmichel: I changed the RFC number and also the URLs because the location is different. 14:13:31 mike: I'll look at it, but I see no reason not to go ahead. 14:13:49 nigel: There are 3 other issues open. 14:14:05 mike: They are unrelated to the media type registration but it would be good to look at them. 14:14:12 nigel: https://github.com/w3c/tt-profile-registry/issues/17 14:15:14 nigel: This just needs someone to follow the agreement from May to add some recommendation text. 14:15:28 mike: The more we write the more developers can get reasonable expectations of what to do. 14:15:42 nigel: The next one is https://github.com/w3c/tt-profile-registry/issues/13 14:17:42 nigel: The two tables in ยง4 have no explanatory text. 14:17:53 mike: It would be good to have a volunteer for this. 14:17:56 nigel: I volunteer. 14:18:24 nigel: The next one is https://github.com/w3c/tt-profile-registry/issues/8 14:18:44 ... which is to merge the profiles document with the note on TTML versions, which is my issue also. 14:19:19 ... https://dvcs.w3.org/hg/ttml/raw-file/5ee90ec0d897/ttml-status/index.html 14:20:10 pal has joined #tt 14:25:36 group: Discussion of what to do with the "TTML Recommendations" snaphot note. 14:25:50 ... Conclusions: 1. Make sure the information is available via the group home page 14:25:55 ... 2. Remove the document. 14:26:16 mike: We should check in with Cyril too on this. 14:26:18 nigel: Agreed. 14:27:14 nigel: I've added a note to the issue on the profile registry and closed it. 14:28:10 mike: I'll check the pull request and merge it. 14:28:17 tmichel: It will then be updated on github. 14:29:16 Topic: TTML2 14:31:35 action-481? 14:31:35 action-481 -- Glenn Adams to Provide nigel with a list of new features in ttml2 to begin reviewing -- due 2016-09-26 -- OPEN 14:31:35 http://www.w3.org/AudioVideo/TT/tracker/actions/481 14:32:12 glenn: There is already http://w3c.github.io/ttml2/spec/ttml2-changes.html 14:32:51 nigel: The action is to editorialise this into something more useful for reviewers. 14:36:12 action-481: [Meeting 2016-10-06] Glenn points to http://w3c.github.io/ttml2/spec/ttml2-changes.html as a technical list. 14:36:12 Notes added to action-481 Provide nigel with a list of new features in ttml2 to begin reviewing. 14:42:35 nigel: Okay I'll draft something if Glenn will review that draft text. 14:42:53 Action-481: Nigel to draft high level summary, Glenn to review. 14:42:53 Notes added to Action-481 Provide nigel with a list of new features in ttml2 to begin reviewing. 14:43:04 action-480? 14:43:04 action-480 -- Thierry Michel to Request schedule time for horizontal review of ttml2 -- due 2016-09-26 -- OPEN 14:43:04 http://www.w3.org/AudioVideo/TT/tracker/actions/480 14:43:44 tmichel: i18n was initiated with TPAC, and some questions have been answered. 14:44:27 ... Then there's the accessibility review - I sent a heads-up notice to them and have not heard back yet. 14:44:49 ... There are two new questionnaires: one is from TAG but I don't think we need to go through 14:45:03 ... that - I discussed with Philippe and Yves and it does not seem to be mandatory. 14:45:17 ... The other is about security - I responded to that for TTWG review. Nigel added a few 14:45:31 ... remarks, so it is still pending. I do not know if I should send the response with Nigel's 14:46:17 ... updates. 14:46:50 pal: What's the latest version? 14:46:51 nigel: https://lists.w3.org/Archives/Public/public-tt/2016Oct/0005.html 14:49:06 glenn: I would also add to q3.6 that we do not consider condition to be a scripting language. 14:50:01 nigel: I agree with that. 14:52:08 pal: We could ask them in q3.6 is only about script loading and script execution. 14:52:11 nigel: Good idea. 14:52:36 ... That would help us understand how to answer this, since we do allow loading of resources, just not scripts, and the question as worded is ambiguous. 14:53:46 glenn: It is true that we have indirectly brought in fetch semantics by the introduction of external resource loading. 14:54:04 ... Also the addition of links on spans that can have hyperlinks. Those two things are probably 14:54:14 ... worth pointing out somewhere. 14:57:04 pal: Somehow they are presumably interested in cross-origin. Maybe in 3.6 we should mention 14:57:15 ... that the specification introduces external resources and let them deal with that. 14:58:20 glenn: There's nothing in TTML2 now that discusses fetch processing. I've given it some 14:58:31 ... thought and I think we are probably going to need to put something in. I want to make it 14:58:36 ... as minimal as possible. 14:58:54 ... My plan is to delegate this to the document processing context. 15:01:07 nigel: We need some words for 3.6. Thierry, do you have enough to write this? 15:01:13 tmichel: I think so, I can craft something. 15:02:53 nigel: Thanks, Thierry if you can edit the responses and recirculate that would be helpful. 15:02:56 tmichel: Yes, will do. 15:03:55 glenn: I want to go over the pull requests that are in process and how to proceed on safe crop area. 15:06:42 nigel: There is an action to submit an issue on CSS - I'm not sure who should take that. 15:07:08 glenn: My preference is for someone active in CSS to file this, because it's more likely that something would happen. 15:08:05 glenn: I'll review a draft issue report. 15:08:10 nigel: Okay, thanks, I'll prepare one. 15:08:45 glenn: I just submitted a new pull request last night, to add new feature designations in 15:08:54 ... Appendix E for most/all of the new features. 15:09:20 ... I have also processed all of the editorial notes that propose new features. 15:09:57 nigel: I think it's too soon to have review comments on this - my concern would be that we 15:10:02 ... get the right level of granularity. 15:10:15 glenn: I am sure that we will tweak this list as we advance towards PR. 15:13:55 nigel: What we need to worry about now is if anyone wants to hold back on a merge of this 15:13:59 ... to allow extra time for review? 15:14:17 nigel: Well it seems that noone does, so go ahead in 2-3 days and merge if you need to Glenn. 15:16:07 glenn: By the way if problems are raised later they would still be fair game for addressing later. 15:17:13 glenn: On Safe Crop Area, I plan to create a new pull request with different wording and 15:17:38 ... incorporate the points raised by Pierre as well as Nigel's original intent. 15:18:28 pal: I have three concerns: 1) Safe Crop Area is not a good term. I would call it Active Area. 15:18:54 ... 2) Should vs Shall. I think it should all be 'should'. 15:19:14 ... 3) We have to make sure it works correctly preserving aspect ratio of the root container. 15:26:38 group: [discussion of these points - too fast for scribe (who is involved!) to write down] 15:27:15 glenn: I propose to separate mandation from feature definition, using feature designation. 15:27:34 pal: I would need to see the pull request to understand if that works for me in this case. 15:29:30 glenn: I think I have enough information to take a stab at text that we can move forward with. Let me do that and I will create a pull request for that purpose. 15:32:24 tmichel has joined #tt 15:36:20 Topic: Next face to face meeting 15:36:41 nigel: I am still offering BBC in February for the next F2F meeting, dates currently tbc, 15:36:57 ... but also want to note that I will likely be at the CSUN conference in San Diego from 1-3 March 15:37:17 ... so having a meeting in California around that time would be a logistical possibility at least 15:37:22 ... for me. 15:38:07 nigel: Okay, we took an extra half hour today - thanks all who were able to linger, for your flexibility.
