15:10:51 [plh]: ... David Singer is working on it
15:11:07 [plh]: ... the issue which is holding us up is the document license one

15:12:16 [plh]: Pierre: at the f2f meeting, we had a thorough review of the charter and everybody seemed happy
15:12:27 [plh]: ... struggling to udnerstand why there is further delay
15:12:48 [plh]: Nigel: yes, but document license is an issue
15:12:54 [plh]: ... hoping we can revert
15:13:04 [nigel]: http://www.w3.org/2013/10/timed-text-charter.html
15:13:12 [plh]: Pierre: which version are we looking at?
15:13:57 [plh]: plkh: problem is that the charter doesn't allow the use of the CC-BY license
15:14:04 [plh]: s/plkh/plh/
15:14:21 [plh]: Pierre: my understanding was that it can take a lot of time to resolve this
15:14:36 [plh]: ... how long are we going to wait?
15:15:02 [plh]: Nigel: we need confirmation that not using an open license is acceptable
15:15:56 [plh]: ... from David
15:17:11 [plh]: Mike: what's the purpose of listing the external groups?
15:17:14 [plh]: plh: getting reviews from them
15:17:34 [plh]: Mike: concerned with DVB and ATSC. no individual/human there who cares
15:18:02 [plh]: ... so we have those groups but no one care to review those documents
15:18:17 [plh]: Nigel: DVB has a subtitle group
15:18:25 [plh]: ... which will be brought back to life
15:18:34 [plh]: ... with ATSC, I can see your concern
15:18:48 [plh]: Mike: problem with ATSC is internal
15:19:14 [plh]: ... my first choice would be to remove DVB and ATSC, since our list is not prohibitive
15:19:27 [plh]: ... if those orgs don't care, I'd prefer not to list them
15:19:41 [plh]: ... how about we leave them off for now?
15:20:37 [plh]: Nigel: do we need to receive a reply?
15:20:48 [plh]: plh: we don't need to, but we should contact them
15:21:41 [plh]: Nigel: adding ATSC came out of the WebTV IG
15:22:19 [plh]: Mike: this came out of a new member from WebTV IG, but no real group within ATSC
15:23:10 [plh]: Thierry: we can't force folks to review our documents
15:23:13 [plh]: Mike: ok, that's fine
15:24:55 [plh]: --> http://www.w3.org/2001/11/StdLiaison Liaison page
15:25:13 [plh]: Pierre: when do we expect the AC review to happen?
15:25:32 [plh]: Nigel: I'll continue to talk to David and get a resolution on this, within the next calendar week
15:25:45 [plh]: ... but I'm dependent on the response from David
15:26:17 [plh]: zakim, move to next agendum

15:46:45 [trackbot]: http://www.w3.org/AudioVideo/TT/tracker/actions/164
15:47:18 [plh]: Glenn: I can send you some email about the issue
15:47:28 [plh]: ... since we don't use CSS syntax, we use XML
15:47:44 [plh]: ... there is an escaping mechanism in CSS that we didn't use
15:48:00 [plh]: ... unicode escaping mechanism
15:48:47 [plh]: ... the question is: if you have a TTML document, and serialize it in CSS, you'll need to be careful
15:49:12 [plh]: Jerry: this seems that it was a cautious choice, there is a note in the spec
15:49:21 [plh]: Glenn: I made the choice, but would like feedback from implementers
15:49:57 [plh]: Jerry: I'll close the loop with Sean
15:50:34 [tmichel]: I amp now back.
15:50:52 [plh]: Mike: do we have an issue here?

15:51:27 [trackbot]: http://www.w3.org/AudioVideo/TT/tracker/issues/286
15:52:43 [plh]: Nigel: slightly extending the background does improve readability, raised within EBU
15:52:56 [nigel]: http://lists.w3.org/Archives/Public/public-tt/2013Dec/att-0000/mim-xmlsubs0149r01.ebutts-padding-diagram.pdf
15:53:44 [plh]: Nigel: we were concerned on this behavior on arbitrary spans. we relaxed the requirement to be on each line
15:54:19 [plh]: ... the pdf illustrates our intent
15:54:51 [plh]: ... proposal is to add an attribute
15:55:26 [plh]: Glenn: didn't have a chance to look at it yet
15:56:29 [plh]: ... we can use padding on span
15:56:53 [plh]: ... not about repetition of padding at line breaks
15:57:34 [plh]: Nigel: CSS box declaration break is at risk
15:57:43 [plh]: ... lack of browser implementation
15:57:48 [plh]: ... and we wuld need it
15:58:17 [nigel]: http://www.w3.org/TR/css3-background/#box-decoration-break
15:58:39 [plh]: Glenn: there is some support for them
15:58:44 [plh]: in opera and chrome
15:59:46 [plh]: Nigel: we'll come back to this one
16:00:01 [plh]: issue-288?
16:00:01 [trackbot]: issue-288 -- Rules for splitting and accumulating documents -- open
16:00:01 [trackbot]: http://www.w3.org/AudioVideo/TT/tracker/issues/288
16:01:28 [plh]: Mike: is this related to the temporal extend of the document?
16:01:30 [plh]: Nigel: yes
16:02:16 [plh]: http://lists.w3.org/Archives/Public/public-tt/2013Nov/att-0026/mim-xmlsubs0133r05.EBU-TT_Segmentation.pdf
16:03:23 [plh]: Mike: this is adding complication and don't prefer it
16:03:33 [plh]: ... would prefer to have hints and metadata
16:03:51 [plh]: ... this piece of content is going to continue in an other document, please watch decoder
16:05:09 [Zakim]: -Plh
16:05:19 [nigel]: Mike: not in favour of constraining the temporal containment, would prefer a hint mechanism
16:05:23 [Zakim]: -Glenn
16:05:29 [glenn]: i need to drop as well
16:09:49 [nigel]: Mike: happy to provide a proposal
16:11:54 [nigel]: nigel: one issue is the scope of uniqueness of xml:id
16:12:16 [nigel]: mike: yes we could typecast the id and add extra uniqueness rules as a hint
16:12:36 [nigel]: ... This may be useful in the archive context too
16:13:04 [nigel]: ... It's not a good idea to try to compute deterministically 'sameness' by comparing text, position, styling etc.
16:13:52 [nigel]: action mike to make proposal re segmentation hints to reflector
16:13:53 [trackbot]: Created ACTION-250 - Make proposal re segmentation hints to reflector [on Mike Dolan - due 2013-12-12].
