I need to reformat and change the SOTD. 15:06:56 ... And I'll review it myself. If there's anything broken, that's discovered in the review, then 15:07:12 ... we can go ahead and fix that. Otherwise changes would be strictly editorial. 15:07:51 nigel: The 2 week review period neatly ends on 29th Jan - is that okay with all? 15:07:54 group: No objections. 15:08:02 pal has joined #tt 15:08:22 https://dvcs.w3.org/hg/ttml/raw-file/tip/ttml2/spec/ttml2-20150114-pre-fpwd-review-1.html 15:09:00 glenn: I took all the open issues and anything that is in a Change Proposal.

The issues are in yellow issue 15:09:32 ... boxes spread throughout the document. 15:09:37 Present+ jdsmith 15:09:53 glenn: That covers all of the open issues against TTML2. Then there are editorial notes which 15:10:03 ... are actions on me, without specific issues marked against them. 15:10:47 nigel: Thierry also reserved the short name ttml2 for this version, in advance of publication. 15:11:01 tmichel: Do you plan to have a difference section comparing it to TTML1? 15:11:14 glenn: There's another document, that will be referenced from the SOTD, describing the TTML2 15:11:17 ... changes. 15:11:22 mike has joined #tt 15:11:34 https://dvcs.w3.org/hg/ttml/raw-file/tip/ttml2/spec/ttml2-changes.html 15:11:51 tmichel: I think that will be very helpful for interested people to check the new functionality. 15:12:02 glenn: I'll reference that from the SOTD. 15:12:04 +Mike 15:12:16 tmichel: That's more like a change log. I was more thinking about something in the introduction 15:12:34 ... mentioning the new concept, important changes etc. It doesn't necessarily need to be done 15:12:42 ... in the FPWD but it would be helpful later. 15:12:47 Present+ Mike 15:13:09 glenn: I could attempt to summarise the technical changes in a paragraph in the Introduction. 15:13:53 ... I'll consider that a Review comment. How are we going to track review comments? 15:14:19 nigel: We don't need a Disposition of Comments formalisation for this internal review.

That in no way denigrates the referenced post though. 15:28:06 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 TTML and WebVTT are both chartered as deliverables by the TTWG. 15:36:50 nigel: We need to move on from this for time. 15:37:28 pal: I'll re-review the response and respond on the reflector. 15:40:01 pal: Proposes that a summary of the charter deliverables and a link to the most recent version 15:40:12 ... of each specification would suffice to answer the question. 15:40:40 WebVTT is timed text for Bolsheviks.
