Action Items

action-268?

<trackbot> action-268 -- Nigel Megitt to Estimate timelines for ttml 2 deliberables with glenn -- due 2014-02-27 -- OPEN

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/268

<plh> TTML2 August 2014 LC, Oct 2014 CR, Jan 2015 PR, Feb 2015 Rec.

nigel: we discussed this on the call last week - see above. Any comments?

plh: PR to Rec could take longer: a minimum of 4 weeks for PR review and then 2 further weeks. No change needed in proposed timeline. Early Jan PR -> late Feb Rec

nigel: any objections to adopting this proposal?

group: no objections

plh: CR->PR is a bit short because implementations are needed.

glenn: I anticipate at least one implementation, namely the TTV verifier to test all the features of TTML2 to be completed quite early in the process. I'll be updating it to verify the spec.
... then there's the issue of other implementations supporting it. TTML2 is a delta on TTML1 so it doesn't entail as many new features as we had with TTML1 so I suspect it will
... be less time consuming.

plh: we used Flash, Silverlight and JS implementations for TTML1. I don't know if we can rely on Flash or Silverlight this time around.

jdsmith: Silverlight is not under active development. We're transitioning to HTML5 so it's not likely that we'll enhance TTML in Silverlight.

plh: Will there be any TTML implementation in IE?

jdsmith: we're not ready to make any announcements about this.

nigel: what about the JS implementation?

plh: I would expect that implementation to be easily upgradeable to TTML2

tmichel: to clarify, what kind of implementation are we expecting? Within browsers?

plh: I don't know. For instance Glenn was mentioning a validator - is that a valid implementation? These things are debatable.

glenn: formally because TTML defines both a presentation and transformation profile any kind of transformation process is a valid implementation so it should count.

plh: I'm biased as author of the JS implementation.

glenn: I'm also working with folks in Opera for implementation of TTML in Chromium so I expect that to move forward and be able to implement the TTML2 features, particularly through the HTML/CSS mapping process.

<plh> https://github.com/plehegar/ttml-js

plh: by the way I put the JS implementation on github for those who are new - I did that 4-5 years ago. It's not maintained.

action-268: Proposed new timeline for TTML2 is August 2014 LC, Oct 2014 CR, Jan 2015 PR, Feb 2015 Rec.

<trackbot> Notes added to action-268 Estimate timelines for ttml 2 deliberables with glenn.

plh: after March 20 I will copy the charter and edit the timeline. I will also make Silvia's requested edit.
