This meeting
nigel: Runs through the agenda. AOB?
group: No AOB
plh: We'll be pushed onto Webex at the end of June. I recommend
you don't worry about it for now.
... In June I'll get the groups to move slowly across. There is
no need to move earlier.
... Once you move you can't move back!
nigel: We have no chair yet for June 18 and June 25 so we could
make the move in the first meeting of
... July.
plh: I recommend waiting until July.
nigel: Does anyone want to chair on 18th and 15th June?
pal: If we have work to do then I recommend planning to hold
the meetings and then we'll find someone
nigel: Okay, works for me!

<trackbot>
[18]http://www.w3.org/AudioVideo/TT/tracker/issues/265
[18] http://www.w3.org/AudioVideo/TT/tracker/issues/265
nigel: This week someone asked on stackoverflow about a timing
test that seems to indicate that the
... default dur for a content element in a seq container is
zero, whereas in fact it's indefinite, so I've
... added the affected tests to this issue.
... I answered the question on stackoverflow - the link is in
the issue. I really hope I got it right!
IMSC CR2
nigel: The status of IMSC CR2 is that it has been prepared,
with the same SOTD but a later 'do not exit before' date.
... I think the next step is to request a meeting for
transition with the Director?
plh: No! I'd rather not talk to the Director on this one. It's
supposed to be lightweight. We do need a
... transition request to be sent to chairs. That hasn't
happened?
nigel: No, nobody has done that.
plh: I'm willing to send the transition request but I need the
proper links and text. I will need the links
... to where comments are addressed and the list of changes,
and I guess that's it. The rest I can take
... from the previous CR.
nigel: We have all that.
plh: Point me to it and I'll generate the transition request.
nigel: List of changes:
[19]https://dvcs.w3.org/hg/ttml/raw-file/3e1440f7f545/ttml-ww-p
rofiles/substantive-changes-summary.txt
[19] https://dvcs.w3.org/hg/ttml/raw-file/3e1440f7f545/ttml-ww-profiles/substantive-changes-summary.txt
plh: I can generate the diff.
... [looks at the list of changes] Okay, I have enough!
nigel: So even though we have assessed the changes and decided
that several of them are substantive,
... we don't need a Director call?
<plh> [20]http://www.w3.org/2014/Process-20140801/#revised-cr
[20] http://www.w3.org/2014/Process-20140801/#revised-cr
<plh> plh: Quote from the process: "Note that approval is
expected to be fairly simple compared to getting approval for a
transition from Working Draft to Candidate Recommendation."
plh: No, you don't need it.
... Hopefully I can go through these changes tomorrow, and if
it's okay, the latest publication date
... will be Thursday next week.
... I can take care of fixing the date up in the CR2 draft.
nigel: Our view on the earliest exit date is date of
publication + 4 weeks.
plh: Thanks for letting me know.
Action-403: [Meeting 2015-05-14] plh informs the group that a
Director call is not needed.
<trackbot> Notes added to Action-403 Arrange director call for
imsc 1 cr2 transition request.
close action-403
<trackbot> Closed action-403.
IMSC Test Suite and Implementation Report
nigel: We've already covered action-402. Anything else to
report here?
pal: Nothing to report
WebVTT comments
courtney: No update
TTML2 Editorial actions
nigel: Glenn, do you have a plan date for next working on the
spec?
glenn: Nothing definite, probably a week or so between now and
the end of June.
nigel: It'd be helpful to set a deadline for delivering
editorial actions so that folk who have taken them on can know
when they're due by.
glenn: I'd say end of June, but I can process examples sooner
since they don't require too much effort.

[21] https://dvcs.w3.org/hg/ttml/file/tip/ttml2/spec/ednotes.xlsx
nigel: I know from previous weeks when we've looked at this
that it's quite sparse - anyone else want to
... take any of the editorial actions?
TTML Versions note
[22]https://dvcs.w3.org/hg/ttml/raw-file/5ee90ec0d897/ttml-stat
us/index.html
[22] https://dvcs.w3.org/hg/ttml/raw-file/5ee90ec0d897/ttml-status/index.html
nigel: How does everyone feel about this document - is it
useful?
atai: It does make sense to have such a document but it needs
more work to explain the contents
... of the document and the relationships of the spec. The
question is what kind of TTML profiles
... should go in there - just for W3C profiles or also those
from other groups? What is the aim?
nigel: It can be what we want it to be. There's no problem
referencing non-W3C specs in a WG note.
atai: It's definitely helpful but I have no resources to work
on it at the moment!
nigel: Okay, well we can keep working on it then and keep this
open.
IMSC CR2 continued
<Zakim> plh, you wanted to ask questions IMSC CR2 transition
plh: I need more on the story here. Where did the changes
originate - members or external organisations?
... Also, for the changes that have been made, what kind of
review did we get on those changes?
... Even if they're substantive, do they affect the previous
review feedback?
... Firstly, where did the changes come from?
pal: They came from the issues filed on the document.
plh: Who filed them - anyone from inside the WG?
pal: I'll have to go back to the issues. Most of them were from
within the WG.
plh: Okay. My second question is, what kind of review can we
claim on those changes or are we confident
... that the changes are good enough.
pal: The resolution to those issues has not been widely
distributed. My personal opinion is that the
... changes are substantive by the process, but they're
extremely limited in scope so I don't feel that the
... document has changed sufficiently to warrant the sort of
wide review that the document already
... has undergone to reach CR.
plh: Okay.
pal: FYI one of the issues was in response to a late comment
received during the CR transition and the
... commenter was happy with it.
plh: Are you aware of any other changes where the commenter
wasn't happy with the resolution?
pal: No
plh: Thanks, now I have my story.
nigel: I second pal's judgment there on the changes being
substantive but not needing further review.
... They are worthwhile however.

Change Proposals
nigel: I just want to check if there's been any update on
HTMLCue and Opera?
Andreas: I had an action to kick off a gathering to discuss
this issue. There's no progress to report right now.
nigel: Glenn, has any of your work resulted in areas of spec
change to TTML?
glenn: Possibly - I've been spending time on Ruby and text
emphasis and how they're formatted in the
... context of what we've implemented in order to handle the
multiRowAlign requirement by treating
... a span as an inline block with a different text align.
There are some subtleties of formatting that are
... not particularly well addressed in CSS that I'll probably
end up needing to articulate in the TTML2
... spec in order to make it more clear. For example the line
separation behaviour of lines that contain
... Ruby that potentially overlap, for example a Ruby below
line followed by a Ruby above line. Does the
... addition of the Ruby cause the line height to be changed?
Is that accomplished by adding leading or
... by changing lineHeight? In the process of implementing
formatting support I've found those. You can
... track that activity by going to the repository and see
what's happening.
<glenn> [24]https://github.com/skynav/ttt/commits/master
[24] https://github.com/skynav/ttt/commits/master
glenn: We recently changed the location of that repository -
you can follow it if you're interested.
... One side effect of this activity is we're generating a lot
of TTML2 test files that include these features
... here's a link...
... Those test files will be very useful when it comes to
creating a test suite for TTML2 I think.
<glenn_> sorry, dropped the line, will post link...

nigel: Thanks glenn!
... Thanks everyone, we'll meet again same time next week.
