I'm largely happy with the agenda as it stands. 14:09:43 https://www.w3.org/wiki/TimedText/geneva2014 14:11:21 atai: We want to propose a mapping from a restricted TTML subset to WebVTT 14:11:59 glenn: One point of advice for that mapping: The best approach is to map TTML document to an ISD sequence, and then map the individual ISDs to VTT cues. 14:12:41 ... my plan is to include in TTML2 a formal definition of an interchangeable form of a sequence of ISD documents. I'll probably define a format: either a single XML document where each child is an ISD document 14:13:04 ... and maybe a second format that is a ZIPped sequence of ISDs with a specific naming format to sequence them in the ZIP file. 14:14:38 nigel: That's an interesting point because there's an alternative which is to create a cue per piece of text with a distinct lifetime, by semantic analysis of the document. I can see merits to both. 14:14:49 glenn: I may have some working code by the F2F to drive some discussion. 14:15:10 topic: Action Items 14:15:32 action-296? 14:15:32 action-296 -- Glenn Adams to Define default for @validationaction to be warn if @validation is optional; otherwise, default is abort -- due 2014-06-12 -- PENDINGREVIEW 14:15:32 http://www.w3.org/AudioVideo/TT/tracker/actions/296 14:16:30 close action-296 14:16:30 Closed action-296. 14:16:35 action-302 14:16:35 action-302 -- Nigel Megitt to Re-review issue-313 -- due 2014-06-26 -- PENDINGREVIEW 14:16:36 http://www.w3.org/AudioVideo/TT/tracker/actions/302 14:17:20 issue-313? 14:17:20 issue-313 -- Presented Region section is informative only -- open 14:17:20 http://www.w3.org/AudioVideo/TT/tracker/issues/313 14:18:12 close action-302 14:18:12 Closed action-302. 14:20:57 issue-313: An acceptable proposal would be to change the wording in §4.6.1 specifically to define the term "Presented region". 14:20:57 Notes added to issue-313 Presented Region section is informative only. 14:21:22 action-303? 14:21:22 action-303 -- Nigel Megitt to Add priority column to change proposal index -- due 2014-06-26 -- PENDINGREVIEW 14:21:22 http://www.w3.org/AudioVideo/TT/tracker/actions/303 14:21:59 https://www.w3.org/wiki/TTML/ChangeProposalIndex 14:23:49 nigel: I've added the priority column - please could the owners of each change proposal now review each and edit the index page to assign the appropriate priority value. 14:24:05 ...

There was also a comment about rounding up vs down. 14:29:34 ... For extent and lineHeight we round up so I added a comment on extent that explains the rationale for this. 14:29:40 nigel: Looks good to me. 14:30:52 pal: I'll take a look. 14:31:06 action-258? 14:31:06 action-258 -- Glenn Adams to Work with pal to resolve edits needed for issue-259 comments -- due 2014-04-01 -- PENDINGREVIEW 14:31:06 http://www.w3.org/AudioVideo/TT/tracker/actions/258 14:31:42 glenn: this is related to action-207. 14:31:44 -Thierry 14:33:02 topic: Issues 14:33:12 issue-263? 14:33:12 issue-263 -- profile feature set may not match intended feature constraints -- pending review 14:33:12 http://www.w3.org/AudioVideo/TT/tracker/issues/263 14:33:44 +Thierry 14:33:49 glenn: I think we're looking for Mike's review of this. 14:34:18 issue-316? 14:34:18 issue-316 -- Wording of 5.2 doesn't make sense -- pending review 14:34:18 http://www.w3.org/AudioVideo/TT/tracker/issues/316 14:35:24 close issue-316 14:35:24 Closed issue-316. 14:36:16 issue-309? 14:36:16 issue-309 -- Image profile needs to permit text equivalent -- open 14:36:16 http://www.w3.org/AudioVideo/TT/tracker/issues/309 14:38:18 nigel: We met the accessibility folk on Monday. The feeling is that as long as there's availability of a text equivalent and a method to find it then the WCAG requirement is met. 14:38:36 pal: Reviewing the changes I've made: 14:39:42 https://dvcs.w3.org/hg/ttml/raw-file/tip/ttml-ww-profiles/ttml-ww-profiles.html 14:39:56 ... in §3.1 the text is clarified to say that distributors should provide a text form of image data that the system can find automatically. 14:40:31 ... in §4.5.4 there's an altText attribute to allow a text string to be added. 14:40:34 q+ 14:41:03 ack nigel 14:41:21 nigel: The normative text doesn't mention accessibility - shouldn't it? 14:42:05 pal: The harm for IMSC to say MAY have accessibility is we don't want accessibility /only/ to be in the alt text because it's better to have a complete alternate text profile document. 14:42:49 pal: Of course there's no prohibition on usage of altText but it's not at all a recommendation. 14:44:23 glenn: defining the contents as #PCDATA is appropriate for an element that can contain text. 14:45:12 atai: This section says "{any attribute not in the IMSC 1.0 Metadata namespace}" which would allow any attribute in TTML 1 namespace, which doesn't seem right. 14:45:40 glenn: That's correct - the table near the top of TTML defines all the tt namespaces that should not be permitted here. 14:46:32 pal: I'll change it to "any attribute not in the default namespace or in the TT namespace or in the IMSC 1.0 Metadata namespace" 14:46:54 s/Metadata / 14:47:53 pal: John Birch provided some text re WCAG so I've moved that to Annex C. 14:47:57 q+ 14:48:06 ack nigel 14:49:39 nigel: The term "application" has been used in various places normatively so I think it needs to be defined. 14:49:44 pal: Or I could remove it. 14:49:52 nigel: Either way - but application is used in several places now. 14:52:44 nigel: I wonder if we should say "In order to meet the guidelines of [WCAG20] the following considerations apply:" 14:52:50 pal: I like that. 14:53:18 pal: I'll create an issue prior to committing those changes. 14:53:55 pal: I've added in Annex D.5 the #altText extension designator is defined. 14:54:44 nigel: I think the #altText extension needs to be added to §6.4. 14:54:46 pal: I'll add that. 14:56:25 glenn: I just added a new issue for IMSC - issue-326. 14:56:47 issue-317? 14:56:47 issue-317 -- IMSC should not require frame alignment -- open 14:56:47 http://www.w3.org/AudioVideo/TT/tracker/issues/317 14:57:21 pal: I've added a note that hopefully captures the use case. 14:57:36 ... in §4.4 15:01:16 nigel: We're close on this one but I need to come back with some proposals for edits. 15:06:24 nigel: adjourns meeting 15:06:49 -Andreas 15:07:49 rrsagent, generate minutes 15:07:49 I have made the request to generate http://www.w3.org/2014/07/17-tt-minutes.html nigel 15:07:55 -Courtney 15:08:01 -glenn 15:08:04 -Thierry 15:08:06 -pal 15:08:10 -nigel 15:08:11 SYMM_TTWG()10:00AM has ended 15:08:11 Attendees were glenn, Thierry, nigel, +1.408.771.aaaa, pal, Andreas, Courtney 17:16:15 Zakim has left #tt
