It may be useful to have 2 hour meetings on an occasional basis to handle overflow. 14:17:51 nigel: We'll schedule next week's meeting (the 19th) for 2 hours. I'll be absent for the next two weeks after that. 14:18:38 topic: SMPTE liaison 14:19:03 Proposed response at https://lists.w3.org/Archives/Member/member-tt/2014Jun/0000.html 14:20:48 nigel: I'll make the change proposed to request for notification of changes to ST2052 14:21:34 glenn: I'll review the response - give me until the end of the day. 14:21:58 nigel: I will aim to send this on Monday next week if there are no further amendments. 14:22:21 topic: Change Proposal 2 14:22:33 https://www.w3.org/wiki/TTML/changeProposal002 14:23:51 jdsmith: We don't need to make the change to step 6 described in the CP because of the way that Glenn has implemented this. 14:24:06 ... I think there's some editorial note to elaborate too. 14:25:05 glenn: I'm in the process of elaborating that editorial note. The final hook is the semantics of inline regions, in particular how the associate region algorithm works in the context of inline regions. 14:25:15 ... I think we can go ahead and close the CP. 14:25:47 jdsmith: Is there another CP that drives the editorial notes? 14:26:13 glenn: Inline regions was a general solution and then this particular proposal formulated it in terms of a syntactic shorthand. 14:26:22 jdsmith: I agree the syntactic element is taken care of. 14:26:42 issue-176? 14:26:42 issue-176 -- Adding support for extent and origin attributes on block elements -- closed 14:26:42 http://www.w3.org/AudioVideo/TT/tracker/issues/176 14:26:54 nigel: Issue 176 is closed at the moment. 14:27:24 jdsmith: The substance of the change proposal is already implemented. 14:28:36 ACTION jdsmith Fix up change proposal 2 to reflect decision on how to implement and edit out now unnecessary sections. 14:28:36 Created ACTION-299 - Fix up change proposal 2 to reflect decision on how to implement and edit out now unnecessary sections. [on Jerry Smith - due 2014-06-19]. 14:29:12 RESOLUTION: Close change proposal 2 following completion of ACTION-299 14:29:34 topic: Pending Review actions and issues 14:29:53 action-293? 14:29:53 action-293 -- Pierre-Anthony Lemieux to Research appropriate namespace for forceddisplay feature in imsc 1 for issue-312 -- due 2014-06-05 -- PENDINGREVIEW 14:29:53 http://www.w3.org/AudioVideo/TT/tracker/actions/293 14:30:42 pal: I completed this action by moving the new attributes introduced by IMSC to an IMSC-specific namespace as proposed by glenn. 14:30:56 pal has joined #tt 14:31:05 pal: the prefixes used are ittp: and itts: 14:31:26 close action-293 14:31:26 Closed action-293. 14:31:50 issue-263? 14:31:50 issue-263 -- profile feature set may not match intended feature constraints -- pending review 14:31:50 http://www.w3.org/AudioVideo/TT/tracker/issues/263 14:33:07 nigel: mike has specifically mentioned this before so I'm minded to hold off closing this until he has had a chance to comment. 14:33:50 glenn: Do we need to go back and amend SDP-US to use the extension and restriction of features. We don't normally update notes post-publication. 14:34:36 nigel: I think we may need to consider a new version of SDP-US based on TTML2 later in our process. 14:35:40 plh: It is not covered by the charter to put SDP-US on a Rec track. 14:35:55 nigel: An alternative is to consider IMSC (1 or 2) as superseding SDP-US. 14:36:21 plh: If we make it a sub-profile of IMSC and update the SDP-US note to point to IMSC that might do the trick. 14:37:26 nigel: Do we need to make a decision on SDP-US to close this issue? 14:38:28 glenn: It would be worth adding a note to the issue. 14:39:34 ACTION glenn to add note to Issue 263 explaining how TTML2 additions for @{extends,restricts} (partially) addresses this issue 14:39:35 Created ACTION-300 - Add note to issue 263 explaining how ttml2 additions for @{extends,restricts} (partially) addresses this issue [on Glenn Adams - due 2014-06-19]. 14:39:37 nigel: After these edits and when Mike has had the opportunity to verify that this meets the requirements he has previously mentioned we can close this off, assuming no objections. 14:39:57 issue-312? 14:40:02 issue-312 -- forcedDisplay attribute is metadata so should be in ttm not tts namespace -- pending review 14:40:02 http://www.w3.org/AudioVideo/TT/tracker/issues/312 14:41:19 pal: In addition to fixing the bug and changing the namespace I added a specific recommended processor behaviour. 14:49:43 nigel: Expresses concern that the approach to conditional content is different to the approach for issue-309 14:50:46 nigel: We also have change proposal 16 https://www.w3.org/wiki/TTML/changeProposal016 to provide for this requirement. 14:52:04 glenn: When we get around to defining something like this in TTML2 I would want to address this not as a special case so I doubt that we will end up with a forcedDisplay style property in TTML2. 14:53:33 nigel: Our options are to omit the feature, add a note in IMSC saying that this is IMSC1 specific, or specify this feature 'properly' and carry forward into TTML2. 14:54:22 pal: I'd propose to do the second option and add a new issue for IMSC 2 to log this. 14:57:40 glenn: By publishing this from this group it will add legitimacy to the feature and possibly people will try to make us carry it into TTML2. 14:58:07 ... I think we should put a note in, if we include it in IMSC1, to the effect that it may not be specified in the same way in TTML2 to cover our tracks and prevent future complaints. 14:59:01 ... I understand that we can't predict the future but it's useful to the reader that they can not expect backward compatibility in a future version. Notes are lightweight anyway. 14:59:58 pal: Entering an issue against IMSC 2 is powerful too. 15:00:05 nigel: Let's do both things. 15:00:39 ... I will add a note to the issue and re-open it immediately after this meeting. 15:02:45 -glenn 15:02:48 -Frans_EBU 15:02:49 -pal 15:02:49 -Plh 15:02:51 -jdsmith 15:02:51 rrsagent, make logs public 15:02:59 -tmichel 15:02:59 Regrets: mdolan 15:03:05 rrsagent, generate minutes 15:03:05 I have made the request to generate http://www.w3.org/2014/06/12-tt-minutes.html nigel 15:03:49 -nigel 15:03:50 SYMM_TTWG()10:00AM has ended 15:03:50 Attendees were +44.192.341.aaaa, nigel, jdsmith, +1.720.897.aabb, glenn, pal, Plh, +41.22.717.aacc, Frans_EBU, tmichel 15:45:13 glenn has joined #tt 16:27:57 Zakim has left #tt
