<nigel> scribeNick: plh
NIgel: activities on issues since last meeting
Prioritise discussion for this meeting
Nigel: let's cover IMSC and issues for tday
... no AOB today
IMSC 1 timeline
NigeL: send email on Friday and didn't see responses
... I'll take that as approval
... this was generated with Pierre btw
... idea is: all issues need to be raised by September 5th
... it's possible that we'll identify some cases where an issue
might fit better in IMSC during the f2f
... so I've left a little window for the f2f
... then Pierre will be able to create a draft for review by
October 15
... so we'll have resolved issues or defer them
... I'll send a liaison to key orgs about the timeline
... feedback?
plh: +1
RESOLUTION: IMSC timeline is approved
Nigel: second part of the IMSC issues
... in upcoming meetings, I'd like to address them
... proposal is to have 2 hours meetings on July 31, August 14
... might skip August 28
Jerry: is that to cover IMSC topics, or make progress on TTML
issues?
Nigel: I try to cover issues regardless of products
Jerry: those dates would work for me
Nigel: for August 28, anybody volunteering to chair?
RESOLUTION: 2 hours meeting on July 31, August 14, and no
meeting on August 28

issue-324 is now open

[20] http://www.w3.org/AudioVideo/TT/tracker/issues/325
Nigel: Glenn raised that one
Jerry: in this case prohibited means disabled?
Nigel: yes, it means you must not validate this
Jerry: what's the use case?
Nigel: I don't know
issue-325: the group would like to see use case(s) for this
<trackbot> Notes added to issue-325 Add 'prohibited' value to
@ttp:validation.
issue-326?
<trackbot> issue-326 -- definitions do not use shall, uses of

<trackbot>
[21]http://www.w3.org/AudioVideo/TT/tracker/issues/326
[21] http://www.w3.org/AudioVideo/TT/tracker/issues/326
Nigel: this is about conformance language
... makes sense to me
326 is now open
issue-327?
<trackbot> issue-327 -- IMSC should meet W3C QA Framework Spec
guidelines -- raised
<trackbot>
[22]http://www.w3.org/AudioVideo/TT/tracker/issues/327
[22] http://www.w3.org/AudioVideo/TT/tracker/issues/327
Nigel: this is generic bucket.
... let's try to meet the best practices as we can.
... is that a reasonnable thing to be asking for?
Plh: it's nice to have but not a priority imho
... let's see what Pierre can do and if you have more specific
concern, you should raise those separately
Nigel: agreed
issue-328?
<trackbot> issue-328 -- ittm:altText should be in TT namespace
in TTML 2.0 -- raised
<trackbot>
[23]http://www.w3.org/AudioVideo/TT/tracker/issues/328
[23] http://www.w3.org/AudioVideo/TT/tracker/issues/328
Nigel: goes back to alt text
... that maybe imsc doesn't meet the WCAG 2 guidelines
... although the resolution didn't require alt text
... it's still a good idea
... so it's imsc 1 and John wants to put in the tt namespace
... ie not part of metadata
Plh: +1 to John
Nigel: I agree as well
issue-309?
<trackbot> issue-309 -- Image profile needs to permit text
equivalent -- open
<trackbot>
[24]http://www.w3.org/AudioVideo/TT/tracker/issues/309
[24] http://www.w3.org/AudioVideo/TT/tracker/issues/309
Nigel: Pierre has made some edits there
... I still need to complete my review but I'm comfortable with
where we got to now
... I suppose there is a question about the alternative
mechanism
Plh: so the meeting with the a11y folks happened?
Nigel: yes. it isn't a requirement that it needs to be provided
in the same doc.
... it's a requirement for the software to find it
... there needs to be metadata about the alternative document
... I think we should close the issue at this stage
close issue-309
<trackbot> Closed issue-309.
issue-313?
<trackbot> issue-313 -- Presented Region section is informative
only -- open
<trackbot>
[25]http://www.w3.org/AudioVideo/TT/tracker/issues/313
[25] http://www.w3.org/AudioVideo/TT/tracker/issues/313
Nigel: that's an IMSC region
... ttml 1 has the concept of temporarily active region
... Pierre has resolved in his edit
... so we have a definition in IMSC 1 now
... I think the proposal is to close issue 313 and raise a new
one
... happy with the approach
Jerry: makes sense to me. it clarifies the remaining issue
close issue-313
<trackbot> Closed issue-313.
<scribe> ACTION: Nigel to create follow-up issue from issue-313
[recorded in
[26]http://www.w3.org/2014/07/24-tt-minutes.html#action01]
<trackbot> Created ACTION-308 - Create follow-up issue from
issue-313 [on Nigel Megitt - due 2014-07-31].
issue-314?
<trackbot> issue-314 -- Temporally active is not defined for
regions -- open
<trackbot>
[27]http://www.w3.org/AudioVideo/TT/tracker/issues/314
[27] http://www.w3.org/AudioVideo/TT/tracker/issues/314
Nigel: temporally active isn't defined and ought to be
... that can be achieve with assigning begin/end time to
regions
... I wonder if folks use regions with timing
... the concept from Glenn is a good one but I don't know a use
case for it
... will continue discussion with Glenn
issue-317?
<trackbot> issue-317 -- IMSC should not require frame alignment
-- open
<trackbot>
[28]http://www.w3.org/AudioVideo/TT/tracker/issues/317
[28] http://www.w3.org/AudioVideo/TT/tracker/issues/317
NIgel: Pierre made an edit that he believes sort out this issue
"A document can be made independent of the frame rate of the
related video object by never using the frames term in a time
expression"
"In circumstances where the video program is downsampled during
delivery, the application can specify that, at playback, the
relative video object be considered the delivered video program
upsampled to is original rate, thereby allowing subtitle
content to be rendered at the same temporal locations it was
authored."
Nigel: I think it addresses my concern
... so if Pierre and I are ok, can we close the issue?
close issue-317
<trackbot> Closed issue-317.
Change proposals
Nigel: the way things look: priority 1 needs to be closed
before FPWD
... Amendments to the set attribute
... HTML5 Mapping semantics
Jerry: change proposal 5 is largely drafted. you expressed a
desire to have those inline. Didn't close the loop with Glenn
yet. the content is there
... just needs to be incorporated
Nigel: can you create an issue on TTML 2 for this?
... and edit the change proposal page
Jerry: sure
Nigel: Audio rendering
... I don't think that needs to be in TTML 2 at this stage
... so if somebody does want to take this on, let me know
... Distribution
... I can't do a lot about it at the moment
... hoping to bring something back
... what if you have a stream of short documents?
Plh: when is FPWD scheduled?
Nigel: no timeline yet
Plh: how about targetting after the september meeting?
Nigel: too early
... would rather do after TPAC
... I'll talk with Glenn as well
<scribe> ACTION: Nigel to propose a timeline for TTML 2 FPWD
[recorded in
[29]http://www.w3.org/2014/07/24-tt-minutes.html#action02]
<trackbot> Created ACTION-309 - Propose a timeline for ttml 2
fpwd [on Nigel Megitt - due 2014-07-31].
Nigel: tests needs to be closed by LC
... I'll be looking for volunteers for that
... Links
<nigel> nigel: If nobody has a use case for links that means it
should have a higher priority then it will be deferred until
v.next
<nigel> nigel: Meeting adjourned.
