This meeting
Nigel: I've scheduled 1 hour for today. On our agenda we have
TTML2 Horizontal Review,
... IMSC (just tests I think), WebVTT. Anything other business,
or other topics to cover?
group: [silence]
Nigel: I won't be available for the next 2 weeks - anyone want
to Chair?
Thierry: I'm out not next week but the following week.
... (the 24th)
Nigel: OK so let's cancel our meetings on 17th and 24th August.
TTML2 Horizontal Review

Nigel: I've done this, and am awaiting any requests for
specific timeslots from CSSWG members.
close action-497
<trackbot> Closed action-497.
Nigel: When I met CSSWG remotely on Friday last week one of the
requests was that we
... don't simply provide a set of attributes/features but
requirements with use cases so
... that the CSS WG can understand better what we are trying to
achieve, in case they think
... there is a better way in the context of CSS as a whole to
achieve the desired result.
... I thought that was a reasonable request - they didn't want
to feel coerced into
... implementing every feature exactly as we've done it.
Pierre: Take a simple example - multiRowAlign. How would that
go?
... There are lots of real world uses we can point to so that
should be straightforward.
Nigel: Good question. I think we'd describe the desired
outcome, and our proposed
... solution, but also accept that they may decide there's some
better way to achieve it.
Pierre: Should we painstakingly catalogue everything and
present it as a batch, or develop
... a working relationship or process starting with one or two
examples and see how that goes?
... I started with multiRowAlign as a low risk one.
... It was a question to you Nigel if you have thoughts of how
we should proceed?
Nigel: My personal view is that there may even be cases where
members of the TTWG
... are not clear about the use cases for all the new features
in TTML2, so it would be
... valuable to us as well as other groups if we could document
example use cases for each
... new feature, especially those that have no CSS equivalent.
So I'd be inclined to try to
... complete the documentation for all those features.
Pierre: I don't disagree.
Nigel: That's a piece of work to do, on top of the existing CSS
Requirements wiki. I suspect
... that without being able to provide that documentation we
will see limited responses
... from CSS WG.
... A lot of the time with TTML2 the explanation has been that
a semantic is present in the
... LambdaCap format and that therefore there is content that
uses it and we need to
... support those features.
Pierre: That would be a legitimate question to Netflix, about
how they selected the
... features needed in TTML2. I think it'd be great for Netflix
to explain that, even in half a
... page. It would be extremely helpful going forward, and it
might even be required to
... persuade people to vote for or implement the spec.
... I think Mike has pointed out in the past that having
evidence for why a feature is
... required is a really good idea. I'm thinking additionally
of IMSC 2.
Nigel: Agreed - this is something we need to go back to Netflix
and Glenn to answer.
... I also attended the Privacy IG who gave some useful
feedback.
... I raised all the feedback I could recall/find in minutes as
TTML2 issues.
... The CSS issue is not exactly the topic we just discussed,
but is about defining the semantics
... of TTML2 style attributes based on CSS where possible or
equivalent.
... I don't think I've heard or seen any other feedback -
Thierry have you heard anything?
Thierry: No, I haven't seen anything else. We asked for
feedback from APA (Accessibility),
... Web Platform, i18n, Media and Entertainment IG.
Nigel: Clearly we have had good feedback from i18n, but nothing
from the others.
Thierry: The review ends at end of September, so if there's
been nothing by end of August
... I should ping them again.
Nigel: +1
Pierre: Due to the timescales I think it will be difficult to
get good feedback from external
... groups in the timescale required. My guess is that they
will begin looking at the spec
... in September. They may simply provide their feedback
whenever they have it.
... Our long review period overlaps with a long period of
vacation too.
Nigel: Thierry are you suggesting reminding the internal W3C
groups only?
Thierry: No I can do all of them.
Pierre: There are industry meetings like IBC in September that
will take time away from
... those groups for review, so maybe remind them in 1st or 2nd
week September and
... accept that the feedback may be a bit later than the
deadline.
... I'm thinking especially about TV and OTT industries.

<trackbot> Created ACTION-503 - Send a reminder to groups for
ttml2 review by 8th september [on Thierry Michel - due
2017-08-17].
IMSC
Pierre: Thinking about processing the issues and the next steps
on IMSC, we said it could
... not progress until 13th August, which is soon. I can
prepare an ED fixes for the issues,
... but we still need the implementations to be reported.
Nigel: I will chase internally - I'm not sure why I haven't
been able to provide our implementation
... yet - could be due to holidays.
Pierre: In any case I will address those two issues.
Nigel: My assumption is that we will not publish an editorial
fix but will only move to PR
... with the new features implemented.
Pierre: That matches my assumption.
Nigel: Worth noting for the minutes that you released the IMSC
tests Pierre, thank you!

Nigel: I just created an issue on this to add it to github-bot,
but I can't assign it to myself.
... What are the permissions on it?
Thierry: I'll check...
Nigel: It looks like it isn't associated with TTWG.
... I think you need to add it into the Timed Text team:

tf8=%E2%9C%93&query=
[17] https://github.com/orgs/w3c/teams/timed-text/repositories?utf8=✓&query=
Thierry: OK yes, added and write permissions added to the TTWG
team.
Nigel: Thanks, that's fixed, I've assigned it to myself.
... The next step for that is for Pierre to create a skeleton
requirements document in
... that repo.
Pierre: Yes.
... My initial goal is to have a first draft by month end.
WebVTT review feedback
Thierry: I had some actions assigned last week.
Action-501?
<trackbot> Action-501 -- Thierry Michel to Write to david and

Thierry: I pinged this to David but I got no response because
he was on vacation so I
... issued a new WD with a 6 week review period, closing on
September 22. That's done.
... Silvia was okay with that.
Action-501: Thierry did this and published a new WD on TR with
a 6 week review period.
<trackbot> Notes added to Action-501 Write to david and the cg
saying we should publish a new wd with a 6 week review period..
close action-501
<trackbot> Closed action-501.
Thierry: I also sent a number of emails to W3C groups for
Horizontal and Wide Review
... which are copied on our public-tt reflector.
Action-502?
<trackbot> Action-502 -- Thierry Michel to Explain to david
that we need a more consistent disposition of comments for
webvtt. -- due 2017-08-10 -- OPEN
<trackbot>
[19]http://www.w3.org/AudioVideo/TT/tracker/actions/502

Thierry: This was about the first review in 2014. We discussed
last week that we should
... have the same procedure as for IMSC and TTML in our group
so I've asked David to
... add the links in the document to emails showing that the
commenters are satisfied with
... the CG resolution. I did not get a response from David but
Silvia has begun to work on
... it and she has provided a number of links. She has also
sent emails to the commenters
... to collect this agreement.
Nigel: I forgot to mention something relevant to this last
week, so apologies. I had said to
... David that we can not go to external commenters to approve
a disposition until the
... CG disposition has been approved by the WG. Otherwise if
the WG doesn't agree with
... the CG then this would put the external commenter in a
difficult position. However at
... this stage there has been reasonable notice to the WG of
the dispositions and no
... further comments have been added so it may be reasonable to
take that as tacit approval
... of the CG dispositions by the WG.
... Can I check if anyone wants more time to review those CG
dispositions?
group: [nobody requests additional time]
Nigel: In that case we should allow it to proceed.
Thierry: That was David's point too - the WG has had 1 month or
more so I consider that
... the WG is satisfied.
... It is not very common in the W3C for a CG and a WG to work
together - it makes things
... a bit more difficult.
... This is a good example - we are three parties instead of
two.
Pierre: Setting aside the dynamics of the groups, from an IPR
perspective it's weird to have
... all the technical work done elsewhere but the IPR
commitment made here.
Nigel: Formally, the main contributors in the CG are members of
the WG. It is weird though.
Pierre: Formally we need to track all the contributions to
check that the IPR is cleared.
... Maybe it's not a problem here, but it is awkward.
Nigel: I think David is across that.
... There was a formal IPR release from the CG back in 2014 I
think, and since then David
... has been tracking it I believe - the small number of
contributors may in fact all be members
... of the WG right now, so this may be ok.
Thierry: I think that closes my actions on this, so I may have
more news on David's return
... from vacation.
Action-502: Thierry sent a message to David and is expecting a
response.
<trackbot> Notes added to Action-502 Explain to david that we
need a more consistent disposition of comments for webvtt..
Action-502: Thierry to turn the existing document into
something more homogeneous.
<trackbot> Notes added to Action-502 Explain to david that we

Meeting close
Nigel: Those are all our agenda topics, so I'll adjourn the
meeting. Thanks everyone,
... next meeting will be 31st August. [adjourns meeting]
