<trackbot> Date: 12 November 2015
<scribe> scribe: nigel
nigel: I've put the pulse pages from git onto the agenda in lieu of the old activity summaries, since tracker can't any longer provide a useful agenda.
<plh> http://www.w3.org/2010/webperf/board/
plh: This contains issues and
pull requests for all of the repos in web performance.
... I can make one of those for TTWG if you would like it.
nigel: Yes please?
<scribe> ACTION: plh Create board for TTWG similar to that for webperf [recorded in http://www.w3.org/2015/11/12-tt-minutes.html#action01]
<trackbot> Created ACTION-449 - Create board for ttwg similar to that for webperf [on Philippe Le Hégaret - due 2015-11-19].
nigel: Any requests for things to discuss today?
pal: Can we review two issues marked for Review for IMSC 1? Based on the TPAC discussion.
nigel: yes!
pal: I'd also like to discuss
next steps on IMSC 1. Two implementors have mentioned
that
... the ED has had a lot of good explanatory text added so it
would be good to publish
... a heartbeat or another CR, to get that to be the version
that is on /TR. Can we figure out
... a timeline and a process? I'll propose the end of
November.
action-425?
<trackbot> action-425 -- Thierry Michel to Send a prompt/thank you to the potential test result contributors for imsc. -- due 2015-10-01 -- OPEN
<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/425
tmichel: That was done, and then
I updated the implementation report and a couple of
... days ago I've tidied it a bit more.
nigel: I restyled it earlier today.
pal: I was going to send another
implementor but I haven't heard back so we should
... close this action for now.
close action-425
<trackbot> Closed action-425.
nigel: Thank you Thierry!
action-429?
<trackbot> action-429 -- Mike Dolan to Draft a wg note for the profile short name registry and ttml media type registration -- due 2015-10-08 -- OPEN
<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/429
mike: No progress to report so far.
nigel: I think it would be good to create a github repo for the note.
mike: I was going to raise that too.
plh: You need a name.
... How should I call it?
<plh> tt-profile-registry
mike: Sounds right
nigel: All happy with that?
<plh> https://github.com/w3c/tt-profile-registry
plh: I've made it!
action-442?
<trackbot> action-442 -- Nigel Megitt to Add an issue to ttml2 for ensuring plain text accessibility -- due 2015-11-05 -- OPEN
<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/442
nigel: Nothing to report so far on this.

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/444
nigel: I'm certain that plh has done this!
close action-444
<trackbot> Closed action-444.
nigel: Thank you Philippe!
action-446?
<trackbot> action-446 -- Pierre-Anthony Lemieux to Go through every feature and make sure that they take into account any dependent features. -- due 2015-11-06 -- OPEN
<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/446
pal: Still in process.
... I'm going to enter this as an issue on github
nigel: Good plan.
... There are two ways to note tasks in github:
... 1. Add a 'task' label.
... 2. Add to the description a tick box markdown, like "* [ ]
Do this task"
... I'm happy for this to be raised as an issue for tracking
purpose.
pal: Okay I'll raise it on github and let's see how that goes.
nigel: In the past I've used both mechanisms - the label for high level actions and the tickboxes for subtasks.
pal: I like that idea so I'll do that.
action-448?
<trackbot> action-448 -- Nigel Megitt to Put timing diagrams somewhere they can be reviews -- due 2015-11-06 -- OPEN
<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/448
nigel: I still need to do
this.
... I will try to do that as a PR on TTML2, to see how that
process works.
... If we move to github issues for actions it will be hard for
me to pull out the actions
... list - plh, is there a way to filter issues labelled as
'task' for example in the board?
pal: On github there are 2 issues
marked as 'review':
... They are #68 and #69.
nigel: Also #81.
pal: Yes, it might be helpful to
have Glenn for that.
... #68 and #69 were done before the move to github so there's
no PR.
... but there are changesets.
https://github.com/w3c/imsc/commit/c7eefbe6831c185fa92ae395b31181a601634152
pal: There's an action on Glenn
to provide a list of simple and complex scripts.
... I've made a start but it may not be complete.
nigel: Do we need Glenn to complete that action before we can close this?
pal: I've specified it
conservatively as 'if it is not simple then it's complex' and
listed the
... simple scripts.
... Being Latin, Hebrew, Cyrillic and Greek.
nigel: There are a small number of variant glyphs in Hebrew.
pal: My understanding is that
it's simple enough to consider as simple.
... It would be good to have Glenn's comprehensive pass at this
before we publish the
... next iteration.
nigel: So we do need that before we close the issue.
<pal> https://rawgit.com/w3c/imsc1/master/spec/ttml-ww-profiles.html
pal: This has the changes in it.
It's linked from the imsc main page on github.
... Section 9.5 defines 'glyph', adds a Note, and the table has
two performance values
nigel: The words 'otherwise' aren't easy to understand - it's not clear what they relate to.
pal: Okay I'll look at ways to address that.
nigel: You could write out all the words, or maybe there's a way to format it so it's clear.
pal: And the list of scripts is in Appendix H.
nigel: I might propose a tweak to
the wording in H - leave it for now though.
... Can we close the issues for now and I'll deal with the
editorial points in a next pass?
... I think the editorial points are important here for
understanding.
... However I agree that the substantive points are dealt
with.
pal: If you're not happy please propose alternate text on #68 and #69.
nigel: Okay I will!
... Should we look at #81?
https://github.com/w3c/imsc/issues/81
pal: Glenn isn't happy that
cellResolution cannot be specified on root. This goes back to
CFF-TT.
... My proposal is not to fix this, unless there's a very
strong reason to. It looks like
... it's just for elegance or symmetry, but is not a
requirement.
nigel: We should also ask what is the implication of permitting ttp:cellResolution?
pal: Well this isn't broken so we
should resist any changes that would impact implementors.
... There's nothing that needs to be done that cannot be done
unless this change is made.
nigel: Please could you summarise that position on the issue?
pal: Yes I will do that.
nigel: The last thing to cover is a new CR version of IMSC1.
pal: Yes.
nigel: We have to resolve the
remaining issues that need to be resolved and update
... the dates in the SOTD.
pal: I think we can do that in the next 2 weeks.
tmichel: We make a snapshot and request another CR.
nigel: So we need a resolution based on a particular snapshot.
pal: So we can set a target for a spec that has all issues resolved...?
nigel: Yes, then when we have
done that then we can prepare a snapshot with an updated
... SOTD and CR exit criteria.
pal: I need to prepare a list of changes and then we can review for how substantive they are.
http://www.w3.org/2015/Process-20150901/#substantive-change
pal: I will focus on that. New features and conformance changes.
nigel: There are quite a few issues right now - what's your plan?
pal: My intent is to resolve them
all so that we have a clean slate. Either fix, wontfix, or
defer to IMSC 2.
... Maybe next week I can put together a proposed plan.
... I'm going to remove the "for review" label on it that made
me reconsider it so I need to go back to him and figure that
one out.
nigel: Our ticket on Unicode has been updated:
http://unicode.org/cldr/trac/ticket/8915
nigel: It has been moved from
milestone 29 to "upcoming". I don't know what that means!
... I think we have no more topics for today, so let's close
the meeting 2 minutes early!
... Thanks everyone [adjourns meeting]
