This meeting

   nigel: Scans through agenda, requests AOB

   group: no AOB

F2F

   nigel: We have our F2F on Thursday and Friday next week.
   ... The wiki page is at
   [11]https://www.w3.org/wiki/TimedText/F2F-april-2015

   ... We have one request to hold the WebVTT discussion topics
   late morning or early afternoon.
   ... I propose that we do that on the Friday
   ... I'll update the agenda later, possibly on Tuesday.
   ... Let's start on the WebVTT and mapping topics at around
   11:30 on the Friday and continue it after lunch.

     [11] https://www.w3.org/wiki/TimedText/F2F-april-2015


   glenn: We can be flexible on the lunch schedule because I'm not
   ordering any lunches - there are
   ... lots of eating opportunities so we can just head out to
   somewhere local when we're ready.

   nigel: Just for everyone's expectations, does that imply that
   lunch will be covered?

   glenn: I'll pick that up.

   nigel: Thank you!
   ... Are there any specific topics that anyone would like to
   have firmly on the agenda and/or
   ... present on at some point?

   glenn: I'll add some items that are flexible in timing - I'll
   do that in the next couple of days.
   ... They may correlate with the wiki page topics already added.
   ... One thing I've been thinking about is background painting
   and the extent of backgrounds.
   ... I'll add an item if necessary.

   nigel: There are some topics that we've planned to discuss for
   a while, such as the timing.
   ... Is there anything else?

   glenn: I'm going to talk about the extent and position
   semantics and pixel aspect ratio.
   ... I've just implemented these in the TTV verifier and a
   presentation engine so I have some direct
   ... experience - it turns out to be pretty straightforward.

   nigel: The agenda isn't closed yet - there's likely to be more
   I suspect, possibly some from me.
   ... If there are no other specific topics for now then I want
   to re-iterate the survey re Sapporo
   ... and the 2015 TPAC. Thanks to everyone who has already
   responded. If you haven't, the survey is
   ... at: [12]https://www.w3.org/2002/09/wbs/34314/TTWGTPAC2015/

WebVTT comments

   tmichel: A couple of months ago I talked to the staff contact
   of the interaction domain for CSS,
   ... HTML and i18n, and requested them to ask their WGs to
   review the WebVTT FPWD. About a
   ... month later we have received a good set of feedback
   comments from i18n. We're still missing
   ... the other three. A few days ago I pinged again Bert and
   Mike. For CSS, Bert has added the
   ... review request to the next CSS agenda. For HTML Paul Cotton
   has followed up on Dave's message.
   ... So we should be set on those two. For accessibility, I know
   plh has pinged Judy again a few days
   ... ago so I hope to get feedback from them but I can't say
   when. I'd like to get the feedback so we
   ... can move to CR when ready.
   ... Another issue is how we handle the comments. Currently
   they're archived in the CG. So at some
   ... point we will have to respond to the commenter and get
   agreement from them so how are we
   ... going to track that?

   atai: Because the comments are on the CG bug tracker and the
   responses are there, should this be
   ... delegated to one place so that everyone can see them? I
   don't think it makes sense to have a
   ... separate tracker for that.

   tmichel: Okay. At some point we have to demonstrate wide review
   to the Director, so are you saying
   ... just look into the archive?

   atai: So it has to be proved that there has been a review and
   that the comments have been
   ... incorporated into the document?

   tmichel: We should have responded to the comments and got
   acceptance for whatever action we
   ... have taken.

   atai: Does this need to be a formal list of raised issues and
   how they've been communicated and dealt with?

   tmichel: Yes, at some point we should have a list of the
   comments and at least some wording from
   ... i18n to say that they're satisfied with each comment. That
   would be good enough.

   atai: Can this be done in the CG, to ask them to follow a
   specific procedure to satisfy the process?

   tmichel: It's not a problem to have it in the CG. We just need
   to show the evidence to the Director.

   atai: My only question is how we handle the same spec in
   parallel in the CG and the WG. Is there a
   ... communication with the CG about the complete process?

   tmichel: I think the CG chair is Dave Singer and there's no
   staff contact. It doesn't matter who
   ... does the job of reporting. What we need is at least a basic
   document describing the dispositions.

   nigel: For IMSC 1 we used the dispositions tracker, but I guess
   that's not the only way.

   tmichel: Agreed. We need at least something.

   atai: Is it possible just to have a spreadsheet referencing the
   bugs?

   tmichel: Yes I think that's good enough.

   atai: And then link to the bug tracker?

   tmichel: Yes that's good enough. You do need the final
   agreement from i18n.

   atai: So we check back with them?

   tmichel: Yes

   pal: We just went through that with IMSC 1 - why not go through
   the same process?

   tmichel: We certainly can.

   atai: I see the problem being additional overhead. Of course it
   worked fine. From my perspective
   ... we need to check that it's okay for the CG. That's my only
   concern.

   pal: But there's only a single consensus group for this work,
   and it's this group. The other group
   ... could be a place for the exchange of ideas, but the formal
   place where the work happens is in
   ... this group if I'm not mistaken.

   atai: That's right, but the groups work differently.

   pal: But as far as W3C is concerned there's only one group and
   its this one.

   glenn: Agreed. Managing the comms is the challenge. There have
   been a lot of cross-postings
   ... which is useful for allowing everyone to have an input, but
   I think the formal decision process
   ... has to happen here.

   atai: Can we agree on this without Dave Singer being here?
   ... What would be good would be to have a close cooperation
   with the CG.

   nigel: There are a number of people interested in progressing
   WebVTT who are in both groups
   ... so I'd encourage those people to take the lead on this.

   Loretta: I think we'd have a hard time persuading the CG to do
   the paperwork but any changes to
   ... the document do need to be agreed by the CG.

   pal: I think by choosing to put WebVTT on the Rec track that
   demonstrated a commitment to follow
   ... the W3C process so that needs to happen.

   nigel: Can I propose that someone who is a member of the WG
   takes ownership of the comments
   ... and documents them, and liaises with the CG to agree all
   actions and responses in both groups?
   ... Can anyone volunteer for that?

   Loretta: Can we pick up on this next week?

   tmichel: Are you proposing a 'two tick' system where both the
   CG and the WG approve every
   ... response to each comment? As well as the original commenter
   e.g. i18n.

   nigel: We could do that - I'm not actually bothered about
   whether the trail of approval between
   ... CG and WG is on the dispositions document or if its managed
   separately. But what I do care about
   ... is that the WG doesn't propose a response that is not
   acceptable to the CG.

   tmichel: This is fairly new so we don't have much prior example
   to work from.

   nigel: It's a good time to be creative with ideas!
   ... If you do have any ideas please bring them to the table
   next Friday.

F2F

   nigel: What is the lead time for dial-in if we want to setup
   Zakim?

   tmichel: I can set up a bridge just a few minutes beforehand.
   ... I had an agenda question: the topics list starts with IMSC
   1 Implementation Report and Test Suite.
   ... My understanding is that we're not ready to report on or
   test implementations during the F2F.
   ... Is that right?

   nigel: I don't know.

   tmichel: Are we expecting anyone to bring along implementations
   or something similar?

   nigel: I don't know. I don't rule out doing so myself! It would
   certainly be welcome.

   tmichel: It would be a great step forward if people do have
   implementations to demonstrate.
   ... That's an invitation!

   nigel: I second that. At the moment it's just a topic
   placeholder.

   nigel: I completed this, uploaded the PNGs and updated the wiki
   page. Not sure if anyone had a chance to review it?
   ... Sorry if I've stepped on your toes there Pierre!

   pal: I looked at it and it looked okay to me. I didn't see any
   problems.

   atai: I haven't had a chance to review yet.

   nigel: In that case I'll leave this pending review for another
   week.

   action-381?

   <trackbot> action-381 -- Pierre-Anthony Lemieux to Prepare new
   list of changes to imsc 1 since cr1. -- due 2015-03-26 --
   PENDINGREVIEW

     [14] http://www.w3.org/AudioVideo/TT/tracker/actions/381


   pal: I sent round a list of the issues and a diff of the html

   nigel: Would you be able to stick the URLs into the W3 diff
   service and send the link round to the output?
   ... It would help make the differences stand out.

   pal: Sure, I'm doing it right now...
   ... Shall I add this to the previous email?

   nigel: That would be good yes.

   action-383?

   <trackbot> action-383 -- Glenn Adams to Missing XML declaration
   -- due 2015-04-30 -- OPEN

   <trackbot>
   [15]http://www.w3.org/AudioVideo/TT/tracker/actions/383


     [15] http://www.w3.org/AudioVideo/TT/tracker/actions/383


   glenn: I want to push this out to the end of April.
   ... I'm going to have to dive deep into the jaxb binding and
   xerces implementation, so I'm not sure
   ... when I'm going to have time to do that.

   nigel: Is this a required part of the authoring process?

   glenn: Yes, I generate the bindings whenever I change the
   schemas.
   ... This isn't a blocking issue, and anyone using the schemas
   is free to add the declaration.
   ... It might be useful if I add a comment in the schema file to
   explain why its missing.
   ... None of the tools I'm using seem to have a problem with the
   missing declaration, and technically
   ... speaking XML doesn't require it. It looks like the reporter
   uses a tool that does want the XML
   ... declaration.

   nigel: I see you've already set the date to April 30th on that
   issue.

Issues

   nigel: There's one raised issue, which I mentioned last week.

   issue-380?

   <trackbot> issue-380 -- The width of content elements' areas is
   unclear, especially looking at the examples -- raised

   <trackbot>
   [16]http://www.w3.org/AudioVideo/TT/tracker/issues/380


     [16] http://www.w3.org/AudioVideo/TT/tracker/issues/380


   nigel: I guess this is what you were referring to for
   discussion next week Glenn?

   glenn: I've been thinking about ways to allow the background of
   a content area to be fitted to the
   ... text content, using a similar approach to what we adopted
   for textAlign, using an inline block and
   ... applying the background colour to the containing regions
   content rectangles only. That might
   ... achieve the right result. I'm going to experiment with CSS
   and see if we can handle it that way.

   reopen issue-380

   <trackbot> Re-opened issue-380.

   nigel: There are 4 pending review issues on IMSC 1, which I'd
   like to close if we can.

   issue-367?

   <trackbot> issue-367 -- Clarify initial value override for
   tts:textAlign -- pending review

   <trackbot>
   [17]http://www.w3.org/AudioVideo/TT/tracker/issues/367


     [17] http://www.w3.org/AudioVideo/TT/tracker/issues/367


   issue-375?

   <trackbot> issue-375 -- Use of the ebutts:linePadding and
   ebutts:multiRowAlign in IMSC 1 -- pending review

   <trackbot>
   [18]http://www.w3.org/AudioVideo/TT/tracker/issues/375


     [18] http://www.w3.org/AudioVideo/TT/tracker/issues/375


   issue-377?

   <trackbot> issue-377 -- Use TTML 1SE rounding rules -- pending
   review

   <trackbot>
   [19]http://www.w3.org/AudioVideo/TT/tracker/issues/377


     [19] http://www.w3.org/AudioVideo/TT/tracker/issues/377


   issue-378?

   <trackbot> issue-378 -- Relax constraints on ttp:frameRate and
   related video object -- pending review

   <trackbot>
   [20]http://www.w3.org/AudioVideo/TT/tracker/issues/378


     [20] http://www.w3.org/AudioVideo/TT/tracker/issues/378


   atai: I've reviewed issue-375 and the changes are fine with me.
   On the informative note I proposed
   ... to delete it because in the block where the application of
   the features is described, it says they
   ... can be specified on style, region, body, div and p because
   IMSC allows inline styling and EBU-TT-D
   ... does not. In the note further down it says EBU-TT-D allows
   linePadding and multiRowAlign only
   ... as children of the style element. Although this is all
   true, I misread it and possibly others would,
   ... to think that because EBU-TT-D is the core reference both
   attributes can only be applied to the
   ... style element. Either we can omit the note or tweak the
   wording to be more in line with what is
   ... said above. I made the proposal in the issue.

   close issue-367

   <trackbot> Closed issue-367.

   close issue-377

   <trackbot> Closed issue-377.

   close issue-378

   <trackbot> Closed issue-378.

   nigel: We're out of time now, so I'll adjourn the meeting. See
   everyone who can be there in person
   ... next week, 9am on Thursday, Las Vegas time! [adjourns
   meeting]
