Agenda+ Action items

This week I've put all the actions in their relevant agenda section.

Agenda+ TPAC 2016

Draft schedule: https://www.w3.org/2016/09/TPAC/schedule.html


Agenda+ Charter

New charter at https://www.w3.org/2016/05/timed-text-charter.html approved.

Need to update home page etc. with new URL.

Agenda+ IMSC

Editor's draft is directly viewable at https://rawgit.com/w3c/imsc1/master/spec/ttml-ww-profiles.html
IMSC Implementation Page: https://www.w3.org/wiki/TimedText/IMSC1_implementation_page.


Press release for IMSC 1 Recommendation and TTML2 WD publication linked from w3.org home page and archived via https://www.w3.org/blog/news/archives/5445?pk_campaign=feed&pk_kwd=world-wide-web-consortium-w3c-expands-emmy-award-winning-work-on-captions-and-subtitles-for-more-accessible-video-content


Agenda+ TTML1 & TTML2 issues, actions, PRs, editorial actions etc

TTML2 WD now published at https://www.w3.org/TR/ttml2/ alongside press release.

We have an updated proposal to discuss briefly on the pull request process: this is as per Glenn's previous proposal except with a minimum of 3 business days between opening a PR and merging it; as before this matches the pull request process used elsewhere with the additional option at the Editor's discretion to merge early and add a label indicating early merge.

I will propose that we accept this new process for a trial period of 3 months and then review it in as lightweight a way as possible.
