- Topic: This Meeting
- 14:05:18 [nigel]
- Nigel: For today I think the main topics are IMSC, and moving IMSC1.0.1 to CR, and TTML2
- 14:05:29 [nigel]
- .. is there anything else?

- 14:05:53 [nigel]
- Topic: TPAC 2017
- 14:06:08 [nigel]
- Nigel: The draft schedule has us meeting on Thursday and Friday, with Web and TV IG
- 14:06:21 [nigel]
- .. on Monday, and CSSWG on Monday and Tuesday, with a suggestion that we invite
- 14:06:58 [nigel]
- .. CSSWG for a joint meeting during our meeting at some time.
- 14:07:24 [nigel]
- Thierry: Will the CSS WG be around on Thursday and Friday?
- 14:07:29 [nigel]
- Nigel: We can ask!
- 14:08:35 [nigel]
- ACTION: nigel Invite CSSWG to joint meeting at TPAC 2017, with list of topics.
- 14:08:36 [trackbot]
- Created ACTION-497 - Invite csswg to joint meeting at tpac 2017, with list of topics. [on Nigel Megitt - due 2017-06-15].
- 14:08:51 [nigel]
- Nigel: I'd like to get a draft list of CSS features that we would need for subtitle and caption
- 14:09:02 [nigel]
- .. presentation, arising from our work on TTML generally.
- 14:09:43 [nigel]
- Pierre: For IMSC1 the obvious ones are multiRowAlign and linePadding.
- 14:09:49 [nigel]
- Andreas: What about line gap?
- 14:09:54 [nigel]
- Pierre: Yes and that too now.
- 14:10:23 [nigel]
- Nigel: I suspect Glenn and/or Dae will be able to list some Ruby features too.
- 14:10:48 [nigel]
- Nigel: It would be good to have CSSWG issues open for those too.
- 14:11:03 [nigel]
- Pierre: Look at #218 on imsc, which indirectly indicates where there is (not) CSS support.
- 14:11:28 [nigel]
- .. For example rubyReserve and rubyOverhang are not supported in CSS. I think Dae did
- 14:11:41 [nigel]
- .. an initial pass at doing that so it probably makes sense to start from there.
- 14:11:45 [nigel]
- Nigel: Thank you I will do that.
- 14:12:51 [nigel]
- Topic: IMSC
- 14:13:01 [nigel]
- Nigel: What are our next steps to move to CR?
- 14:13:15 [nigel]
- .. Thierry, you collated some wide review feedback this week?
- 14:13:26 [nigel]
- Thierry: Yes, since yesterday I need to do more updates because Pierre has been answering
- 14:13:36 [nigel]
- .. more comments so I will continue to update that wiki page.
- 14:13:49 [nigel]
- Pierre: My suggestion is to run down the list of issues.

- -> https://github.com/w3c/imsc/issues/243 Recommended character sets considered harmful #243
- 14:17:02 [nigel]
- Pierre: I have both a question of substance and of process. This question came out of the
- 14:17:20 [nigel]
- .. i18n and we were not involved in the discussion being filed. Part of the issue is there's
- 14:17:34 [nigel]
- .. been a misread of the specification, folk reading more into non-normative text compared
- 14:17:48 [nigel]
- .. to normative text. My take is that this is a misunderstanding, and I'm trying to find the
- 14:17:54 [nigel]
- .. best way to resolve the misunderstanding.
- 14:18:40 [nigel]
- .. There are two other i18n issues, which fall into a similar category. How do we resolve those?
- 14:18:59 [nigel]
- Nigel: Were they all filed by Addison?
- 14:19:08 [nigel]
- Pierre: One was, the others by Richard.
- 14:19:44 [nigel]
- Nigel: I'll invite Richard and Addison to attend this meeting next week so we can talk through
- 14:19:54 [nigel]
- .. the issues and check we understand properly what their thinking is.
- 14:20:39 [nigel]
- Mike: We could raise pull requests to clarify the language.
- 14:20:50 [nigel]
- Nigel: I agree, that was my thinking, but I'm worried that we might not address whatever
- 14:21:06 [nigel]
- .. caused the misunderstanding, if we don't discuss it and find out by conversation.
- 14:22:23 [nigel]
- Nigel: I think it will be most effective if we find a way to discuss this first.
- 14:22:47 [nigel]
- ACTION: nigel Invite i18n to discuss IMSC 1.0.1 issues
- 14:22:47 [trackbot]
- Created ACTION-498 - Invite i18n to discuss imsc 1.0.1 issues [on Nigel Megitt - due 2017-06-15].
- 14:23:23 [nigel]
- Pierre: In #243 I don't know what clarification can be made.
- 14:23:35 [nigel]
- -> https://github.com/w3c/imsc/issues/241 Requirement to support certain Code Point #241
- 14:24:01 [nigel]
- Pierre: My conclusion is we can improve the text to refactor the recommendation to use
- 14:24:15 [nigel]
- .. certain metrics with the recommendations for certain character sets. I don't disagree that
- 14:24:32 [nigel]
- .. the current text is not the most straightforward. I'm reluctant to do this in IMSC 1.0.1, so
- 14:24:43 [nigel]
- .. since it is not exactly a blocker I would prefer to defer it to IMSC2.
- 14:24:59 [nigel]
- Andreas: The text is there and I think it is correct but could be read differently so there is
- 14:25:10 [nigel]
- .. maybe no strict requirement to update it, though it could help to do so. What would be
- 14:25:27 [nigel]
- .. helpful is if the reader is clear that the code points listed are not ones for which support
- 14:25:40 [nigel]
- .. is mandatory, so it is just about the metrics. From the text you could read that if you have
- 14:25:55 [nigel]
- .. this code point and render it then you should produce a glyph sequence which is identical
- 14:26:24 [nigel]
- .. to the reference fonts. Maybe the edge case is that if someone has no glyph in the font
- 14:26:41 [nigel]
- .. for the code point then he may nevertheless render it with a substitute glyph. So if the
- 14:26:56 [nigel]
- .. condition is there (because the glyph is being rendered) then the glyph sequence
- 14:27:30 [nigel]
- .. rendering must be identical to the reference font, which is circular because it implies
- 14:27:34 [nigel]
- .. that the code point must be supported.
- 14:28:21 [nigel]
- Pierre: There are two conditions - §7.3 Reference fonts only is supposed to apply when the
- 14:28:25 [nigel]
- .. glyphs are supported.
- 14:28:30 [nigel]
- Nigel: I never understood it that way.
- 14:28:48 [nigel]
- Pierre: The reference font section §7.2 says which code points should be supported. Then
- 14:29:04 [nigel]
- .. §7.3 says "if you're going to support a code point for a reference font AND it is in the list
- 14:29:49 [nigel]
- .. in Annex A" then you must end up with the same result, but it does not compel support
- 14:29:53 [nigel]
- .. for all the code points.
- 14:30:27 [nigel]
- Andreas: Would it be possible to add explicitly a condition that it only applies when all
- 14:30:40 [nigel]
- .. the code points are supported by the font used to meet the reference font requirements?
- 14:30:48 [nigel]
- Nigel: +1
- 14:30:58 [nigel]
- Pierre: I don't think that would be controversial - it is the intent already. I would be happy
- 14:31:01 [nigel]
- .. to clarify that.
- 14:31:26 [nigel]
- .. [adds a note to the issue] I will generate a pull request that clarifies this.
- 14:32:22 [nigel]
- -> https://github.com/w3c/imsc/issues/239 Clarify "All regions shall not extend beyond the root container" #239
- 14:32:58 [nigel]
- Pierre: There's a pull request open for that.
- 14:33:09 [nigel]
- Nigel: I just added an approval for that (it was wording suggested by me).
- 14:33:30 [nigel]
- -> https://github.com/w3c/imsc/issues/237 Why exclude hebrew and arabic proportional reference fonts? #237
- 14:33:41 [nigel]
- Pierre: This is an i18n comment. I think we ended up rewording one of the sentences and
- 14:33:52 [nigel]
- .. Nigel you suggested a tweak, so I'm tempted to generate a pull request to use as input
- 14:33:55 [nigel]
- .. to our discussion.
- 14:34:29 [nigel]
- Nigel: Makes sense.
- 14:34:36 [nigel]
- Pierre: I will generate a pull request [adds note].
- 14:34:51 [nigel]
- -> https://github.com/w3c/imsc/issues/236 Should the character sets be minimum *font* requirements? #236
- 14:35:08 [nigel]
- Pierre: The recommended character sets is worded as an authorial requirement rather than
- 14:35:24 [nigel]
- .. a processor requirement. This occupied a lot of discussion for IMSC 1 so I'm reluctant in
- 14:35:31 [nigel]
- .. IMSC 1.0.1 to change it into a processor requirement.
- 14:36:01 [nigel]
- .. I propose a "won't fix" for IMSC 1.0.1 and add it to the list of things to discuss with i18n.
- 14:36:12 [nigel]
- Nigel: Ok.
- 14:36:23 [nigel]
- -> https://github.com/w3c/imsc/issues/235 imsc1-all.xsd has a bad pointer for SMPTE-TT schemas #235
- 14:37:19 [nigel]
- Mike: The current IMSC 1 uses the SMPTE 2010 namespace and I'm on a mission to develop
- 14:37:31 [nigel]
- .. some tight schemas for IMSC 1. When I started digging into this I discovered that the
- 14:37:43 [nigel]
- .. backgroundImage wasn't documented until the 2013 namespace, so if you were to try
- 14:37:58 [nigel]
- .. to write a comprehensive schema you would get stuck there. It is trivial of course, as per
- 14:38:15 [nigel]
- .. the email I sent. The question is how to go about addressing this. We could write to
- 14:38:26 [nigel]
- .. SMPTE and note that 2010 is missing backgroundImage, but the answer would probably
- 14:38:53 [nigel]
- .. be to use 2013. Or we could write it ourselves but it would be a little weird to write
- 14:38:59 [nigel]
- .. something in the SMPTE namespace.
- 14:40:07 [nigel]
- .. It would be disruptive to switch to the 2013 namespace because it is incompatible
- 14:40:10 [nigel]
- .. with the 2010 namespace.
- 14:40:37 [nigel]
- Pierre: To Mike's suggestion, we or SMPTE could conceivably create a 2010 schema.
- 14:40:51 [nigel]
- Mike: All we need is one attribute of type xs:anyURI.
- 14:41:07 [nigel]
- Pierre: We either create that one definition and move on, or get SMPTE to write it so that
- 14:41:10 [nigel]
- .. they have control of it.
- 14:41:24 [nigel]
- Mike: There's maybe a hybrid where we ask SMPTE to do it but offer to do the work.
- 14:41:54 [nigel]
- Pierre: Or we could create it, send it to SMPTE and ask them to publish it.
- 14:44:47 [nigel]
- Nigel: This is informative only. [traces through the SMPTE references]
- 14:47:21 [nigel]
- Mike: There's an example in ST2052-1-2010 where smpte:backgroundImage has a URI
- 14:47:38 [nigel]
- Nigel: I see there's a substantive issue here in that the normative specification isn't completely
- 14:47:49 [nigel]
- .. clear that backgroundImage takes a URI, though it can be inferred. Possibly we need to
- 14:48:02 [nigel]
- .. add a clarification to IMSC1.0.1. On the schema, which is informative I'm not so bothered.
- 14:48:20 [nigel]
- Mike: That's why 2013 was done! I think it would be good to clarify in IMSC 1 and offer a
- 14:49:02 [nigel]
- .. proposed update to the 2010 schema to include it. While we're writing to SMPTE we can
- 14:49:14 [nigel]
- .. also ask to verify that it is supposed to be an xs:anyURI.
- 14:49:40 [nigel]
- Mike: I'll draft the liaison to SMPTE, and we ought not to touch IMSC1 until we get an
- 14:49:52 [nigel]
- .. answer back and then there will probably be a follow-up action to modify the spec.
- 14:51:11 [nigel]
- Nigel: [adds note to issue]
- 14:51:37 [nigel]
- Mike: Aside from this issue, the question I have for this group is, if I write all these schemas
- 14:51:51 [nigel]
- .. and post them as a contribution, how do we attach them to IMSC1.
- 14:52:18 [nigel]
- s/1./1?
- 14:53:38 [nigel]
- Nigel: We can just add it to the linked documents we publish. Another alternative is we
- 14:53:59 [nigel]
- .. could create a new repository just for the schemas and link to that. It is much easier for
- 14:54:04 [nigel]
- .. people to use that way too.
- 14:54:07 [nigel]
- Mike: Sounds good to me.
- 14:54:11 [nigel]
- Pierre: +1
- 14:54:29 [nigel]
- Mike: Then it provides a good way to update it in case any changes are proposed later.
- 14:54:31 [nigel]
- Nigel: Agreed.
- 14:55:08 [nigel]
- Nigel: Should we add a new repo?
- 14:55:25 [nigel]
- Pierre: The schemas are already in the spec repo. We could keep it there as a directory
- 14:55:40 [nigel]
- .. and when it feels right to create a repo, do that. We can do everything we want on a
- 14:55:53 [nigel]
- .. separate branch on the IMSC repo and when we're ready create a separate repo.
- 14:56:03 [nigel]
- Mike: I like the first part, maybe we don't need to create a new repo.
- 14:56:29 [nigel]
- Nigel: Okay, works for me.

- -> https://github.com/w3c/imsc/pull/242 Recommend avoiding tab characters #232
- 14:58:09 [nigel]
- Pierre: As you point out Nigel, it seems valuable to explain this unusual exception. I also
- 14:58:16 [nigel]
- .. do not like informative text. Glenn seems to oppose it.
- 14:58:44 [nigel]
- Nigel: Glenn says a note would be acceptable but bad practice.
- 14:58:56 [nigel]
- Pierre: I'm happy to not have it, put it in the text or put it in a Note.
- 14:59:01 [nigel]
- Nigel: I prefer to put it in a Note.
- 14:59:33 [nigel]
- Pierre: The text will say "should not use the TAB character" and the note will say that no
- 14:59:49 [nigel]
- .. presentation semantics are specified for the code point.
- 14:59:53 [nigel]

- Pierre: I left the ticket open because we need disposition comment from the commenter,
- 15:01:15 [nigel]
- .. but we have a conclusion in the group.
- 15:02:03 [nigel]
- Nigel: Where did this come from originally?
- 15:02:07 [nigel]
- Pierre: From the ARIB liaison.
- 15:03:12 [nigel]
- Nigel: I believe that we only need to send a message back to the commenter explaining
- 15:03:24 [nigel]
- .. the disposition, and offering a last opportunity to comment.
- 15:03:37 [nigel]
- Mike: We can send a link to the ED to make it easier, and to the issue.
- 15:03:39 [nigel]
- Nigel: Yes.
- 15:03:56 [nigel]
- Thierry: We don't need to publish a new WD say.
- 15:05:20 [nigel]
- Nigel: We have so few comments here I don't think we need a tool.
- 15:05:59 [nigel]
- Thierry: Yes, I think manually will be good enough. We can use GitHub also, if the commenter
- 15:06:01 [nigel]
- .. adds a note.
- 15:06:09 [nigel]
- Nigel: That's good for i18n say but not for ARIB.
- 15:06:15 [nigel]
- Thierry: So for ARIB we will send an email.

- 15:10:35 [nigel]
- Thierry: Looks good to me.
- 15:10:40 [nigel]
- Nigel: The implementation report is a wiki page.
- 15:10:44 [nigel]
- Pierre: Like for IMSC1.
- 15:11:05 [nigel]
- Nigel: The Exit Criteria Test Suite is a 404.
- 15:11:47 [nigel]
- Pierre: Yes that is because github.io won't let you browse directories - it needs to point to
- 15:11:51 [pal]
- https://github.com/w3c/imsc/tree/4f199de739945656838423d18ff8df6235be4277/imsc1/spec/exit-criteria-tests

- 15:13:07 [nigel]
- Pierre: That directory has TTML files and PNGs.
- 15:13:47 [nigel]
- Nigel: And the examples match what is in the spec for fillLineGap.
- 15:13:54 [nigel]
- Thierry: And there are just two.
- 15:14:11 [nigel]
- Pierre: I think that is sufficient for this particular case.
- 15:14:14 [nigel]
- Thierry: Yes.
- 15:14:28 [nigel]
- Pierre: Especially since the fillLineGap test is pretty gnarly.
- 15:14:31 [nigel]
- Nigel: Agreed.

- Nigel: Any other comments?
- 15:14:51 [nigel]

- .. tts:fontFamily. I think we are getting close to a resolution, so when we get there I will
- 15:16:29 [nigel]
- .. generate a pull request for IMSC1.
- 15:16:38 [nigel]
- .. I have not seen any comments back on the reflector about this issue.
- 15:16:42 [nigel]
- Nigel: Me neither.
- 15:17:11 [nigel]
- Pierre: And Nigel and Glenn prefer option 2 so I think we will go with that.
- 15:17:32 [nigel]
- Nigel: If we have not had any more comments by this time next week shall we just go with

- .. without copying the referenced schemas in.
- 15:20:46 [nigel]
- Nigel: [closes issue]
- 15:20:57 [nigel]
- Andreas: [leaves]
- 15:21:11 [nigel]
- Pierre: That completes the review of IMSC 1.0.1 issues scheduled for CR.
- 15:21:51 [nigel]
- Nigel: So the next step is to complete the disposition with i18n and write to ARIB about
- 15:24:24 [nigel]
- .. two issues. Thierry please could you find the usual boilerplate, and send it to Pierre?
- 15:24:29 [nigel]
- Thierry: Yes I will do that tomorrow.
- 15:24:36 [nigel]
- Pierre: I will draft the email.
- 15:24:39 [nigel]
- Nigel: Thank you both.
- 15:25:19 [nigel]
- Topic: TTML
- 15:26:16 [nigel]
- -> https://github.com/w3c/ttml2/issues/384 Appendix R [June 4 ED] is overly constrained and does not represent current best practice #384
- 15:26:34 [nigel]
- Nigel: I'm preparing a pull request for this.
- 15:28:02 [nigel]
- .. I'm concerned that progressive decoding is not always possible.
- 15:28:19 [nigel]
- Mike: My concern is that all of the text in the appendix should be removed, so I'd like to
- 15:28:31 [nigel]
- .. start there, and then if someone argues the existing text is fine then discuss that.
- 15:28:34 [nigel]
- Nigel: That works for me.
- 15:30:41 [nigel]
- Nigel: I plan to add a section referencing ISOBMFF and EBU-TT Live explaining the temporal
- 15:30:47 [nigel]
- .. fragmentation approach used there.
- 15:31:24 [nigel]
- Mike: I would like to take the TTML1 approach out and just reference it as an alternative.
- 15:32:01 [nigel]
- .. Then this appendix is shorter. I know there's a document by Cyril about this.
- 15:32:16 [nigel]
- Nigel: Oh yes that's on github, written by Romain, Cyril and me. We could reference that
- 15:32:19 [nigel]
- .. informatively.
- 15:32:28 [nigel]
- Mike: I'm concerned about how stable that is though.
- 15:32:54 [nigel]
- Nigel: Okay I understand, I'll submit a pull request along those lines for review.
- 15:33:06 [nigel]
- .. I'll put a picture in too, because that's always helpful.
- 15:33:10 [nigel]
- Mike: That sounds fine.
- 15:33:26 [nigel]
- .. And rather than perpetuate the fragmentation mechanism, just point back to TTML1.
- 15:33:49 [nigel]
- Nigel: Okay I'll make some changes and make that happen.
- 15:35:10 [nigel]
- -> https://github.com/w3c/ttml2/issues/128 Support for conditional styling. #128
- 15:35:28 [nigel]
- Nigel: I just want to check with you about this even in the absence of Glenn.
- 15:37:07 [nigel]
- .. Is it okay not to be able to conditionally select a region for content based on whatever
- 15:37:22 [nigel]
- .. input parameters are available? I think it might be because the properties of the selected
- 15:40:23 [nigel]
- .. region can be conditionally set without having to choose a whole different version.
- 15:40:35 [nigel]
- .. Otherwise we might end up needing to change the region attribute to IDREFS.
- 15:40:47 [nigel]
- Pierre: I need to see use cases for this otherwise I don't know how to evaluate it.
- 15:41:04 [nigel]
- Nigel: Makes sense to me. The way I'm thinking right now is that using condition to support
- 15:41:23 [nigel]
- .. media queries (screen size) and user preferences (e.g. text size) would be helpful, even
- 15:41:35 [nigel]
- .. in IMSC2 perhaps. But I'm not settled on a firm viewpoint on that just yet.
- 15:43:22 [nigel]
- Mike: I second Pierre's concern here that we need to understand the requirements.
- 15:44:32 [nigel]
- Nigel: Okay I agree that we need to address practical considerations primarily, and I haven't
- 15:44:45 [nigel]
- .. any evidence so far to say that we should make any more changes relative to what is
- 15:44:49 [nigel]
- .. present currently.
- 15:45:04 [nigel]
- .. So I will not open a new issue on this right now.
- 15:48:10 [nigel]
- Nigel: On the issue of foreign namespace elements and where they can go, we discussed
- 15:48:23 [nigel]
- .. it in the context of IMSC 1 and TTML1 but there's no issue for it in TTML2 as far as I can
- 15:48:29 [nigel]
- .. see. Maybe one is needed.
- 15:48:30 [atai]
- atai has left #tt
- 15:49:10 [nigel]
- Nigel: I'm hesitant to raise an issue without checking that there actually is one, in case
- 15:49:15 [nigel]
- .. changes have already been made to TTML2.
- 15:49:21 [nigel]
- Mike: I can do that right now.
- 15:49:24 [nigel]
- Nigel: Thank you.
- 15:50:05 [nigel]
- .. I think we've run out of agenda, a little ahead of time, so I'll close for today.
- 15:50:10 [nigel]
- .. Thank you all! [adjourns meeting]
