Topic: Action Items
14:26:25 [nigel]
14:26:25 [trackbot]
action-430 -- Thierry Michel to Look into merging the group home page and the wiki home page and propose something -- due 2015-10-15 -- OPEN
14:26:25 [trackbot]
14:27:05 [nigel]
tmichel: I started to look at this and I think the proposal I will send is to keep the current home
14:27:20 [nigel]
... page as a landing page because each working group has that kind of landing page. Then
14:27:34 [nigel]
... I will highlight that most of the information is on the wiki and include a link.
14:28:04 [nigel]
nigel: Other people seem to have a better home page. Are we stuck with CVS?
14:28:18 [nigel]
tmichel: Yes the home page is under CVS. I propose to keep links to the charter, participants,
14:28:32 [nigel]
... how to join etc that don't move much in time, and then all the more volatile information
14:28:36 [nigel]
... should be kept in the wiki.
14:28:50 [nigel]
nigel: That's the status quo but with a clearer home page.
14:29:06 [nigel]
tmichel: Yes, I plan to simplify the page and make it clear that they need to go to the wiki
14:29:14 [nigel]
... for more information - currently it's not easy to find that wiki link.
14:30:03 [nigel]
close action-430
14:30:04 [trackbot]
Closed action-430.
14:30:31 [nigel]
Action: tmichel Update CVS hosted landing page to simplify and highlight link into wiki page
14:30:31 [trackbot]
Created ACTION-433 - Update cvs hosted landing page to simplify and highlight link into wiki page [on Thierry Michel - due 2015-10-22].
14:30:46 [nigel]
14:30:46 [trackbot]
action-421 -- Nigel Megitt to Check with ttml player manufacturers if they're happy to be listed on our site. -- due 2015-09-24 -- OPEN

14:30:52 [nigel]

14:31:29 [nigel]
Topic: TPAC 2015
14:32:15 [nigel]
nigel: I've added to the wiki page the request to demo TTML2 on the Thursday.
14:32:23 [nigel]
14:33:04 [nigel]
nigel: Are there any requests for specific days to cover specific topics?
14:33:13 [nigel]
dakim: The netflix request is for the Thursday
14:33:19 [nigel]
nigel: Thanks, that's already noted.
14:33:43 [nigel]
nigel: Any other preferences for particular dates, slots etc?
14:33:55 [nigel]
nigel: If not then I'll allocate them as is convenient.
14:34:50 [nigel]
... The other thing to note is the charter discussion: if anyone has any scope changes they
14:35:10 [nigel]
... would like to propose then this will be the time to do that. Otherwise we'll simply be
14:35:14 [nigel]
... proposing an extension in time.
14:35:38 [nigel]
Topic: Incoming Liaison from ATSC
14:35:43 [nigel]
14:37:24 [nigel]
nigel: This is a request to make a derivative work based on part of TTML2
14:37:46 [nigel]
mike: This is a request to comply with the W3C copyright notice. We were planning to put
14:38:07 [nigel]
... the new text under a different namespace. Plh advised that this is still a derived work and
14:38:23 [nigel]
... needs internal approval. He wanted us to come here first and get the group's view.
14:38:55 [nigel]
nigel: The first point is that the current text does not match what we agreed as per
14:38:57 [nigel]
14:38:57 [trackbot]
issue-224 -- Support text placement in 3D coordinate spaces (not zIndex compositing). -- open
14:38:57 [trackbot]
14:39:10 [nigel]
mike: Yes, hence the request to keep tracking developments.
14:39:51 [nigel]
nigel: Right now I'd be unhappy for ATSC to adopt what we know is definitely not what we want.
14:40:13 [nigel]
pal: The first step is to make the changes.
14:40:28 [nigel]
nigel: Yes, the Editor hasn't done that yet.
14:40:35 [nigel]
pal: Maybe someone else could edit that section?
14:40:49 [nigel]
nigel: Yes, that would be okay.
14:41:17 [nigel]
mike: I wanted simply to address the legal compliance question, but we should follow this through.
14:41:23 [nigel]
... I have asked Glenn about making the fixes.
14:41:47 [nigel]
pal: So ATSC would ideally like to copy and paste from a W3C Editor's Draft?
14:42:04 [nigel]
mike: Right - the previous liaison was that ATSC would like to reference the 3D part, and our
14:42:23 [nigel]
... reaction was that we couldn't give a timescale, so ATSC has asked to derive from and track
14:42:28 [nigel]
... the latest state.
14:42:45 [nigel]
pal: And the challenge is that to copy/paste from a rec track doc the WG needs to approve it?
14:43:05 [nigel]
mike: There's a boilerplate W3C policy on copying, and it's not permitted to make a derivative
14:43:19 [nigel]
... work. Even though we're not changing the text but we are moving it to an ATSC namespace,
14:43:26 [nigel]
... plh considered it to be a derivative work.
14:43:44 [nigel]
pal: Imagine someone were to come across a working draft of a W3C spec and love it. Nothing
14:44:03 [nigel]
... prevents that person from referencing a paragraph in that spec, at their own risk. W3C rules
14:44:13 [nigel]
... don't prevent that.
14:44:15 [plh]
present+ plh
14:44:29 [nigel]
mike: No, that would be fine. Past experience is that those were ethereal. Unless the group
14:45:07 [nigel]
... wants to make sure the Working draft URL is persistent.
14:45:22 [nigel]
nigel: The /TR Working Drafts already have a static link.
14:45:36 [nigel]
pal: Also the links to changesets in Mercurial can be used.
14:45:43 [nigel]
nigel: I wouldn't recommend that.
14:45:52 [nigel]
plh: We don't guarantee the stability of those links.
14:46:16 [nigel]
pal: Until the WD is updated.
14:46:22 [nigel]
plh: Why can't we update the WD?
14:46:32 [nigel]
pal: It would take work! I'm not sure what state it is in.
14:47:22 [nigel]
nigel: I think the actions are 1) make the edits to tts:disparity and 2) publish a new WD.
14:47:30 [nigel]
... Would that work Mike?
14:47:54 [nigel]
mike: Yes as long as the WD link is permanent. The ATSC process is ongoing too by the way.
14:48:28 [nigel]
nigel: Can anyone volunteer to fix up tts:disparity?
14:48:34 [nigel]
pal: Yes I can do that.
14:48:38 [nigel]
nigel: Great, thank you.
14:49:09 [nigel]
mike: The expectation is that it matches CEA 708.1.
14:49:10 [nigel]
pal: Yes
14:49:26 [nigel]
nigel: As far as I know there are two ways of doing this, which differ only by a factor of 2.
14:49:28 [nigel]
pal: I can do that.
14:49:43 [nigel]
mike: Thank you. You should drop Glenn a note because he considers it to be his action right now.
14:50:08 [nigel]
issue-224: [Meeting 2015-10-15] pal volunteers to do the editing to implement this
14:50:08 [trackbot]
Notes added to issue-224 Support text placement in 3D coordinate spaces (not zIndex compositing)..
14:50:30 [nigel]
pal: In terms of the liaison back, we need to indicate that this is a WD of TTML2, and it is a draft
14:50:49 [nigel]
... so the group has spent some time on it but please don't depend on any of the document.
14:51:03 [nigel]
mike: That goes without saying. Why don't I draft a liaison request, saying Request Denied, but
14:51:07 [nigel]
... we have good news!
14:51:13 [nigel]
nigel: Sounds good to me!
14:51:35 [nigel]
Action: mdolan Draft outgoing liaison to ATSC proposing to reference an updated WD of TTML2
14:51:35 [trackbot]
Created ACTION-434 - Draft outgoing liaison to atsc proposing to reference an updated wd of ttml2 [on Mike Dolan - due 2015-10-22].
14:53:19 [nigel]
nigel: Can I propose that pal, you don't push the regenerated HTML but just the XML and ask
14:53:35 [nigel]
... Glenn as Editor to pull it and generate the HTML before pushing so he has a chance to review.
14:53:43 [nigel]
Topic: TPAC
14:54:04 [nigel]
pal: I would like to revisit the topic of moving away from tracker towards github and other tools.
14:54:30 [nigel]
... The lack of notifications on changes with tracker is becoming a blocker. Can we take 30 minutes
14:54:37 [nigel]
... to revisit that topic and see if now is a good time.
14:54:44 [nigel]
plh: I'm interested in that conversation.
14:55:05 [nigel]
pal: I've found with tracker that it's tough to notice comments that people have added to issues.
14:55:20 [nigel]
nigel: Is there wider context?
14:55:34 [nigel]
plh: You're probably one of the last WGs using Mercurial and Tracker - most other groups
14:55:50 [nigel]
... have moved to github, which has problems too but many advantages. I would favour moving
14:55:52 [nigel]
... to github.
14:56:35 [nigel]
nigel: I have no problem with that, but I'm interested in the mechanics. Can issues be migrated?
14:56:50 [nigel]
plh: There's no way to migrate the issues from tracker. I think there's a way to migrate the
14:56:58 [nigel]
... Mercurial repo while keeping its history.
14:57:04 [nigel]
pal: Yes there is.
14:57:16 [nigel]
plh: I'm happy to show how other groups are using github during the TPAC meeting.
14:57:24 [nigel]
nigel: Great, let's consider that added!
14:57:35 [nigel]
Action: nigel add tools to TPAC agenda
14:57:36 [trackbot]
Created ACTION-435 - Add tools to tpac agenda [on Nigel Megitt - due 2015-10-22].
14:58:24 [nigel]
Topic: Profiles registry
14:58:26 [nigel]
14:58:26 [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
14:58:26 [trackbot]
14:58:41 [nigel]
mike: The learning curve was higher than I expected. Pal is lending a hand but it's going to
14:59:02 [nigel]
... take a bit of work. I can make Cyril's suggested changes on the wiki. I've got other things
14:59:44 [nigel]
... to do so it won't happen before TPAC. The publishing process is interestingly complex.
15:00:16 [nigel]
mike: I was going to edit the recent other note but it's quite contorted to do by hand. The structure is quite complicated.
15:00:25 [nigel]
... Then the Mercurial post needs to be sorted out.
15:01:12 [nigel]
nigel: You might want to start with a fresh Respec doc or there's also bikeshed.
15:02:16 [nigel]
... Thierry, do you have an empty template you can send?
15:02:38 [nigel]
tmichel: Yes I'll send Mike an empty template. Do you want to make it a Note?
15:02:43 [nigel]
mike: I think we agreed to do that.
15:02:46 [nigel]
tmichel: Okay.
15:03:04 [nigel]
Action: tmichel Send mdolan an empty respec based Note as a starting point for action-429
15:03:04 [trackbot]
Created ACTION-436 - Send mdolan an empty respec based note as a starting point for action-429 [on Thierry Michel - due 2015-10-22].
15:03:56 [nigel]
nigel: Let's take a 3 minute break and come back to look at IMSC issues for the second half of the meeting...
15:09:14 [nigel]
Topic: Issues
15:10:17 [nigel]
15:10:17 [trackbot]
issue-406 -- #lineBreak-uax14 is never 'used' by a document? -- pending review
15:10:17 [trackbot]
15:10:52 [nigel]
pal: I modified this to mandate lineBreak-uax14 for text profile and leave silent for image profile.
15:12:08 [nigel]
pal: nigel raised a separate issue about profiles that we can deal with separately.
15:12:44 [nigel]
close issue-406
15:12:44 [trackbot]
Closed issue-406.
15:12:52 [nigel]
15:12:52 [trackbot]
issue-407 -- Excluding #bidi and #direction on image profile is inconsistent -- pending review
15:12:52 [trackbot]
15:13:29 [nigel]
pal: To summarise, some features in TTML1 imply other features. This was a case where there
15:13:55 [nigel]
... was an inconsistency so I tried to correct that inconsistency as proposed by the commenter,
15:14:10 [nigel]
... by saying #bidi is not applicable in the image profile because not all included features are
15:14:12 [nigel]
... supported.
15:15:26 [nigel]
nigel: On image profile, are some of the implied features prohibited?
15:15:38 [nigel]
pal: Yes. So bidi cannot be used in its entirety.
15:17:18 [nigel]
nigel: Okay I see, #writingMode-horizontal is permitted (from the common features) but
15:17:47 [nigel]
... since #direction and #unicodeBidi are prohibited then it does not apply.
15:18:46 [nigel]
nigel: I'd suggest removing the "Not applicable" since it's not the spec's job to decide that.
15:18:50 [nigel]
pal: ok
15:19:53 [nigel]
issue-407: [meeting 2015-10-15] Propose new text: "See implied features: some are prohibited, others are permitted"
15:19:53 [trackbot]

15:21:47 [nigel]
nigel: I started a thread on this but haven't had the answer yet. My view is to go ahead with this

15:22:07 [nigel]
pal: Can you propose some specific text?

Action-432: [meeting 2015-10-15] nigel to check on details and propose specific wording

15:27:48 [nigel]
pal: I've just posted an update that changes this one as well as the one nigel just suggested.
15:28:52 [nigel]
pal: #writingMode now says "See implied features: some are prohibited, others are permitted."
15:29:00 [nigel]
... And I've added the change set to the issue.
15:29:28 [nigel]
nigel: Are there any other partial ones?
15:29:33 [nigel]
pal: I searched and couldn't find any other.
15:30:13 [nigel]

15:30:59 [mike]
dropping for another meeting
15:31:06 [nigel]
nigel: Since I know there are other bigger issues with profiles I don't want to spend any more time on these

15:32:12 [nigel]
nigel: After the last change I made a proposal.
15:33:49 [nigel]
pal: So you wanted to add a note to Example 2 saying how it would look on a 4:3 display also?
15:33:51 [nigel]
nigel: Yes.

nigel: My aside was just because the numbers seemed like magic - which maths sometimes does!
15:35:02 [nigel]
pal: I'm going to implement that change right now...
15:35:17 [nigel]
s/that./that. I think that's an excellent suggestion.

issue-420 -- The TTML timing vocabulary does not have elements -- pending review
15:39:03 [trackbot]
15:40:34 [nigel]
nigel: The easy path here is to remove "or element" isn't it? That would strictly be correct.
15:41:01 [nigel]
pal: I don't think so. TTML1 ยง10 is "Timing Element Vocabulary"
15:42:07 [nigel]

15:46:13 [nigel]
nigel: I added a comment to this.
15:46:45 [nigel]
pal: Actually itts:forcedDisplay does not modify the computed value of tts:visibility. And more
15:47:08 [nigel]
... importantly the document conformance should be independent of displayForcedOnlyMode.
15:47:42 [nigel]
nigel: I see - itts:forcedDisplay does not modify the computed value of tts:visibility.
15:47:55 [nigel]
pal: It used to be like that but based on Glenn's earlier feedback it was changed to be independent.
15:48:58 [nigel]
nigel: I don't think there's any change needed here. Maybe the phrasing "allows the processor to override the computed value" isn't helpful.
15:49:14 [nigel]
pal: To me that's a different issue, but I agree. If you want to propose new wording to the
15:49:20 [nigel]

issue-434 -- Behavior in case of multiple images in a region -- open
15:55:11 [trackbot]

issue-424 -- Awkward text re: smpte:backgroundImage dimensions -- open
15:55:23 [trackbot]
15:55:42 [nigel]
pal: These issues are questions about document non-conformance. IMSC 1 specifically does
15:55:59 [nigel]
... not specify behaviour in this case. Glenn suggested guidance would be helpful. I've tried
15:56:11 [nigel]
... drafting generic advice on dealing with non-conformant documents. The problem is that
15:56:24 [nigel]
... fundamentally this is dependent on the application and the user preference. Two extreme
15:56:27 [nigel]
... examples:
15:56:42 [nigel]
... 1. During authoring I would expect an authoring tool never to emit a non-conforming document.
15:56:59 [nigel]
... 2. A player - I would hope that a player should do its best to do something with a non-conformant document.
15:57:12 [nigel]
... Because the circumstances are so broad I don't think it's possible to come up with a generic
15:57:26 [nigel]
... definition with conformance text for behaviour in case of a non-conformant document. We
15:57:51 [nigel]
... could go down the path of exploring all the scenarios. I'm not sure if we could ever do that
15:58:06 [nigel]
... in a useful way. I've not been able to find anything that makes sense and is helpful and
15:58:17 [nigel]
... non-harmful.
15:58:37 [nigel]
dakim: With non-conformance, you just have to handle it. A spec document isn't the place for
15:58:52 [nigel]
... that. Just don't address it. It's your problem!
15:59:04 [nigel]
nigel: I think that's fair.
15:59:23 [nigel]
pal: In that case I'm happy to close those issues, maybe with a note, until someone has a better idea.
