This Agenda
nigel: notes that Further Ahead section needs to extend into
November.
Santa Clara F2F TPAC
[13]http://www.w3.org/wiki/TimedText/tpac2014
[13] http://www.w3.org/wiki/TimedText/tpac2014
nigel: I've updated the wiki page. Please fill in the Attendee
section.
... For agenda items, please go through me.
glenn: I expect to have more on TTML2 as I wrap up some more
things.
nigel: Lists members and observers registered for TPAC. I plan
to allow all observer requests.
IMSC 1 WD External liaisons
nigel: I've sent liaisons internally to all the relevant W3C
groups on our charter.
... I've drafted an external liaison and discussed some edits
with Pierre. The main question is who should we write to.
... There's a very long list of potential recipients, taking
into account the charter and the liaisons. There are 38
liaisons including 27 for WAI.
pal: It would be a useful reference point to consider the wide
review requirement in the 2005 process for LC -> CR.
... I'm concerned that we could send this to too many groups.
glenn: I agree that we should only send to those groups that we
can expect a timely response from.
tmichel: I agree too - the Director will be satisfied if we
only talk to the groups on the charter.
[14]http://www.w3.org/2001/11/StdLiaison.html
[14] http://www.w3.org/2001/11/StdLiaison.html
nigel: I would propose to send to the charter groups and the
liaisons noted as interested in Timed Text and Web and TV.
pal: I'm concerned about generating too many conversations.
glenn: DLNA may just come back to me, if at all. HbbTV may be
interested in it though.
... Remember that we need to demonstrate primarily that there's
been wide review and secondly some technical feedback.
nigel: I've decided to send to the charter list and the
liaisons listed for Timed Text and Web and TV.
... Summarises content of note.
<inserted> pal: the notes above did not capture my input
correctly re: sending an email blast to multiple groups without
a clear knowledge of whether the group is interested (and/or
who the right contact is): (a) it generates work for both TTWG
and the target group with only limited chances of feedback, (b)
many of these groups have members that are already members of
W3C and TTWG and (c) it looks like it is not required from a
process perspective
Action items pending review
action-236?
<trackbot> action-236 -- Glenn Adams to Review consistent use
of "root temporal extent" in both ttml 2 and ttml 1 se -- due
2014-08-31 -- PENDINGREVIEW

[15] http://www.w3.org/AudioVideo/TT/tracker/actions/236
nigel: The link doesn't work for me.
glenn: This is a known issue with the Mercurial server, and
occurs sporadically.
... I introduced the mediaOffset, however we have some ongoing
discussion on that.
close action-236
<trackbot> Closed action-236.
glenn: The biggest question for me on this whole topic is: what
is the meaning of BEGIN(document) - is it 0s always or
something else? Nigel's asked that too.
... I'm still considering this.
... In other words is BEGIN(document)-ORIGIN(document)=0 in all
cases or is it possibly non-zero in some cases.
action-286?
<trackbot> action-286 -- Glenn Adams to Send an email to
public-tt describing the ttv hosting site at w3c -- due

close action-286
<trackbot> Closed action-286.
glenn: To get the w3c version back up I need to interact with

site in the meantime.

ยง4 on namespace extension in ttml2 and as an errata to ttml1 --

[19] http://www.w3.org/AudioVideo/TT/tracker/actions/320
glenn: I made a minor editorial note to the codecs registry
page. I'd note that we haven't concluded on this topic.
... This should be an agenda topic at the F2F, because we
should have the right people present, hopefully.
<pal> +1
<scribe> ACTION: nigel Add codecs registry to F2F agenda at
TPAC [recorded in
[20]http://www.w3.org/2014/10/02-tt-minutes.html#action01]
<trackbot> Created ACTION-336 - Add codecs registry to f2f
agenda at tpac [on Nigel Megitt - due 2014-10-09].
close action-320
<trackbot> Closed action-320.
Actions overdue
nigel: These are both mine and I haven't done them.
Action items due next week
Action-332?
<trackbot> Action-332 -- Glenn Adams to Add schema support for
ISD vocabulary -- due 2014-10-01 -- OPEN
<trackbot>
[21]http://www.w3.org/AudioVideo/TT/tracker/actions/332
[21] http://www.w3.org/AudioVideo/TT/tracker/actions/332
glenn: I have coded the newly defined ISD spec into the TTV and
created a TTX transformer tool that allows ISDs to be created
from a TTML file.
... In this way I'm verifying the viability of the newly
defined vocabulary.
action-333?
<trackbot> action-333 -- Pierre-Anthony Lemieux to Create a one
pager to cover the plan for the director's meeting for taking
imsc1 to cr. -- due 2014-10-02 -- OPEN
<trackbot>
[22]http://www.w3.org/AudioVideo/TT/tracker/actions/333
[22] http://www.w3.org/AudioVideo/TT/tracker/actions/333
nigel: Let's postpone this one due to the change in plan for
IMSC.
TTML2 FPWD
nigel: We planned to do this last week; that didn't happen.
glenn: I'd like to retarget this to around the time of TPAC, to
get some substantial pieces in, primarily the ISD creation
rules and the HTML mapping.
nigel: Okay I'll rejig the timeline and discuss with you. I'm
tempted to go just after TPAC so the group can feedback if
necessary.
glenn: Sounds good. I'm making good progress on a variety of
issues and it's better to get more in than less, if we can.
... Also, once we have the FPWD published it's simple to
publish new ones - we don't have to go long between them.
... I'm expecting to close the P1 CPs by FPWD.
Issues Pending Review
issue-228?
<trackbot> issue-228 -- Ruby text support -- pending review
<trackbot>
[23]http://www.w3.org/AudioVideo/TT/tracker/issues/228
[23] http://www.w3.org/AudioVideo/TT/tracker/issues/228
glenn: I mapped 3 style properties that map to the CSS ruby
display styles for the base and different container types and
delimiter.
... And there are position and align attributes. This gives us
a good baseline to work with and supports the basic Ruby text
needs.
... There's one open technical issue that was posted by pal for
SMPTE compatibility, which is the need to specify the offset of
the container boxes from the base box.
... I didn't do that because HTML and CSS don't support that at
the moment. We could define properties but they wouldn't have a
mapping.
nigel: I also noted that it uses a syntax different to the HTML
syntax, and requires nested spans. I don't have an issue with
that though.
pal: So now would be a good time to review?
glenn: yes.
... There are different flavours of syntax in XHTML and HTML5
and the CSS formulation shows that no markup is needed, just
some style properties.
... I took the more CSS approach to make the Ruby more
orthogonal via styling than adding new markup with the extra
overhead for that.
pal: The SMPTE submission from ST4287 is in use today with
content being made today with that Ruby markup so we should
have a good rationale for
... ignoring the recommendations there.
glenn: The proposal didn't say to adopt the syntax from SMPTE.
pal: Re the need to offset, that caught my attention. We should
be careful about not supporting features from things that are
actually in use today.
glenn: If what is proposed is functionally inadequate then I
suggest that issues are raised with the specifics.
nigel: I suggest pal reviews and we leave this as Pending
Review in the meantime.
... Adjourns meeting. We have 1 hour scheduled for next week.
Thanks everyone.
