15:04:49 [nigel]
Present+ Andreas
15:05:08 [nigel]
group: No AOB.
15:05:41 [nigel]
Topic: TTML2 version for review
15:06:16 [nigel]
nigel: Glenn has prepared a snapshot of TTML2 for review prior to FPWD.
15:06:38 [nigel]
glenn: This is static for the purpose of review. I need to reformat and change the SOTD.
15:06:56 [nigel]
... And I'll review it myself. If there's anything broken, that's discovered in the review, then
15:07:12 [nigel]
... we can go ahead and fix that. Otherwise changes would be strictly editorial.
15:07:51 [nigel]
nigel: The 2 week review period neatly ends on 29th Jan - is that okay with all?
15:07:54 [nigel]
group: No objections.

15:09:26 [jdsmith]
jdsmith has joined #tt
15:09:26 [nigel]
... an issue for HTML5 mapping, so I added Issue-365 for that. The issues are in yellow issue
15:09:32 [nigel]
... boxes spread throughout the document.
15:09:37 [nigel]
Present+ jdsmith
15:09:53 [nigel]
glenn: That covers all of the open issues against TTML2. Then there are editorial notes which
15:10:03 [nigel]
... are actions on me, without specific issues marked against them.
15:10:47 [nigel]
nigel: Thierry also reserved the short name ttml2 for this version, in advance of publication.
15:11:01 [nigel]
tmichel: Do you plan to have a difference section comparing it to TTML1?
15:11:14 [nigel]
glenn: There's another document, that will be referenced from the SOTD, describing the TTML2
15:11:17 [nigel]
... changes.
15:11:22 [mike]
mike has joined #tt
15:11:34 [glenn]
15:11:51 [nigel]
tmichel: I think that will be very helpful for interested people to check the new functionality.
15:12:02 [nigel]
glenn: I'll reference that from the SOTD.
15:12:04 [Zakim]
15:12:16 [nigel]
tmichel: That's more like a change log. I was more thinking about something in the introduction
15:12:34 [nigel]
... mentioning the new concept, important changes etc. It doesn't necessarily need to be done
15:12:42 [nigel]
... in the FPWD but it would be helpful later.
15:12:47 [nigel]
Present+ Mike
15:13:09 [nigel]
glenn: I could attempt to summarise the technical changes in a paragraph in the Introduction.
15:13:53 [nigel]
... I'll consider that a Review comment. How are we going to track review comments?
15:14:19 [nigel]
nigel: We don't need a Disposition of Comments formalisation for this internal review. I suggest
15:14:20 [glenn]
action glenn add paragraph in intro that summarizes changes from TTML1 (comment from TM)
15:14:20 [trackbot]
Created ACTION-364 - Add paragraph in intro that summarizes changes from ttml1 (comment from tm) [on Glenn Adams - due 2015-01-22].
15:14:34 [nigel]
nigel: using the Tracker because that's most trackable!

15:19:19 [trackbot]
15:20:34 [nigel]
nigel: There's been quite a bit of debate about this resulting in a most recent draft.
15:21:25 [nigel]
pal: I think it is inappropriate to send the link to Andreas's post.
15:22:15 [nigel]
pal: From a form perspective I think we need to be more formal.
15:22:46 [nigel]
... That in no way denigrates the referenced post though.
15:28:06 [glenn]
TTML is a functional superset of WebVTT and is based upon XML. WebVTT is not based on XML, but is a simpler plain text format, intended to be written by simple authoring tools.
15:30:14 [glenn]
TTML and WebVTT are both chartered as deliverables by the TTWG.
15:36:50 [nigel]
nigel: We need to move on from this for time.
15:37:28 [nigel]
pal: I'll re-review the response and respond on the reflector.
15:40:01 [nigel]
pal: Proposes that a summary of the charter deliverables and a link to the most recent version
15:40:12 [nigel]
... of each specification would suffice to answer the question.
15:40:40 [glenn]
WebVTT is timed text for Bolsheviks. TTML is timed text for Mensheviks. ;)

15:51:40 [nigel]

issue-235 -- Feathering of shadow and outline effects -- pending review
15:54:48 [trackbot]
15:55:16 [nigel]
glenn: Both issue-235 and issue-235 are handled by dropShadow - I'm anticipating adding
15:55:43 [nigel]
... something similar to region as well. I believe this handles the SMPTE/DC request.
15:56:00 [nigel]
... Just to remind folks, textOutline is similar, but has an 'outset' rather than an x and y offset.
15:56:21 [nigel]
... It's along the vector of the tangent to the outline. Whereas shadow allows an x and y offset.
15:56:40 [nigel]

issue-285 -- Align rendered rows within a region to each other, and the set to the region -- pending review
15:58:32 [trackbot]
15:59:10 [nigel]
glenn: This allows a textAlign property on span, which turns it into an inline block with a
15:59:24 [nigel]
... distinct alignment to the paragraph. So it's functionally equivalent. I've also tested it with
15:59:27 [nigel]
... a few browsers.

issue-286 -- Extend the background area behind rendered text to improve readability -- pending review
15:59:42 [trackbot]
16:00:11 [nigel]
glenn: Here I enhanced the semantics of padding to say that if applied to a span then clone
16:00:25 [nigel]
... applies at line breaks as opposed to the non-clone (slice) semantics. That happens to be
16:00:40 [nigel]
... distinct from what browsers implement so a mapping process may need to insert a property
16:00:45 [nigel]
... to handle it.
