13:09:22 [Mark_Vickers]
Topic: Revised TTWG charter
13:10:16 [Mark_Vickers]
Pierre: The main addition to the charter is WebVTT
13:11:02 [olivier]
q+
13:11:09 [Mark_Vickers]
... There seems to be support in the TTWG, but some opposition on AC list discussion. Can the Web & TV industry provide some direction.
13:13:15 [Mark_Vickers]
Olivier: One thing that could be useful is to point to adoption of both specs. Both specs have wide adoption. AC statements that TTML is irrelevant & noxious are concerning.
13:13:49 [olivier]
q-
13:13:55 [Mark_Vickers]
Pierre: TTML has had great adoption. It is the responsibility of W3C to harmonize the two.
13:16:38 [Mark_Vickers]
Glenn: Harmonize implies merging into one. I expect both will exist. I think it will be good for both to be in one group. There has been much misinformation on TTML, for example on XSL. Having both in one group will decrease partisanship.
13:17:37 [Mark_Vickers]
... Cox has asked for specific language in the charter asking for a level playing field and support of both.
13:18:28 [olivier]
Mark_Vickers: we've had too much of a focus on tech issues, not enough IMHO on doing what's best for people with hearing impairments
13:18:34 [glenn]
http://lists.w3.org/Archives/Public/public-tt/2013May/0082.html
13:18:35 [olivier]
... more important than this vs that architecture
13:18:46 [glenn]
http://lists.w3.org/Archives/Public/public-tt/2013May/0087.html
13:18:49 [olivier]
... in that regard fewer specs would be better than more
13:19:10 [olivier]
... would be good to see all TTML variants pulled into one
13:19:31 [olivier]
... and make sure we can maximally map the semantics between the two, if there are to be more than one spec
13:19:46 [olivier]
... if there can't be a mapping, we would lose information

13:21:06 [Mark_Vickers]
glenn: Do you think it's realistic that one community will give up one sntax?
13:23:46 [Mark_Vickers]
olivier: I don't think that it's realistic for there to be one spec given current usage.
13:24:32 [Mark_Vickers]
mark_vickers: I agree it's unlikely to be one spec, but I think it's worth stating that it's an ideal.
13:25:30 [Mark_Vickers]
glenn: I don't agree with a single spec notion because I think it's impractical and causes more trouble.
13:26:08 [Mark_Vickers]
... I agree it's important to serve the community for captions, both hearing and hearing-impaired.
13:26:32 [Mark_Vickers]
Pierre: What about the goal of maximizing semantic compatibility?
13:27:19 [Mark_Vickers]
glenn: To some degree. The goals of TTML were broader, for example in the use of SMIL. I wouldn't expect WebVTT to adopt that.
13:27:47 [Mark_Vickers]
Pierre: But to the amount that one is a semantic superset of the other>
13:29:53 [Mark_Vickers]
mark_vickers: what about when semantics cannot be mapped?
13:30:07 [Mark_Vickers]
glenn: browsers need to support both formats
13:31:13 [Mark_Vickers]
glenn: The superset format can be mapped, but some information will be lost.
13:31:24 [pal_]
http://www.w3.org/2011/webtv/wiki/Timed_Text_Efforts
13:32:22 [Mark_Vickers]
pierre: Would it be worth sharing the TF list of adoption of TTML & WebVTT to show adoption of both?
13:32:41 [Mark_Vickers]
... Can we come up with a requirement that all are happy?
13:34:54 [Mark_Vickers]
glenn: it would be useful to identify the caption communities
13:39:16 [Mark_Vickers]
olivier: the audio group has a hierarchy of developer, implementor, spec maker. In the case of timed text: user, author, implementor, spec maker
13:40:10 [Mark_Vickers]
glenn: I'd order user, author first, but whether implementor or spec maker is first is unclear
13:41:02 [Mark_Vickers]
olivier: an example is if something is tedious to specify, but important for implementors, you need to do the spec
13:43:52 [Mark_Vickers]
glenn: I see the order as user, {author, implementor, spec maker} with the latter an unoredered list
13:44:36 [Mark_Vickers]
pierre: I think author is a priority over the latter two
13:45:15 [Mark_Vickers]
glenn: How about user, author, {`implementor, spec maker}?
13:46:11 [olivier]
"ensure maximal interop"?
13:46:48 [Mark_Vickers]
pierre: Some progress on community. How do we get to agreement on the points on mapping?
13:47:06 [Mark_Vickers]
olivier: I like maximize semantic mapping
13:49:57 [Mark_Vickers]
... what really worries me is that if the two evolve together, there will be mapping from one to the other, but if there's not a clear decision of which is a superset, we're in trouble
13:50:22 [Mark_Vickers]
glenn: I like "Ensure maximal semantic interop"
13:51:06 [Mark_Vickers]
... right now I beliebe WebVTT is a subset of TTML, as far as I'm aware.
13:51:51 [Mark_Vickers]
... for example TTML ability to specifiy feature priority
13:53:20 [Mark_Vickers]
... if WebVTT is kept as a subset of TTML, that would maximize interop
13:53:56 [Mark_Vickers]
pierre: that is beyond the ability of this group,
13:54:06 [pal_]
- pal's notes
13:54:10 [pal_]
- need to provide better information
13:54:13 [Mark_Vickers]
glenn: Perhaps just state one could be superset of another
13:54:19 [pal_]
- minimize profiles
13:54:26 [pal_]
- user, author, {implementer, spec maker}
13:54:35 [pal_]
- ensure maximal semantic interop (one syntax might be a superset of the other)
