Hour(s) IMSC 2 and TTML2 publication events: see the timeline of upcoming work at https://www.w3.org/wiki/TimedText/Publications#Timeline_of_TTML2_and_IMSC2_work Agenda+ TPAC 2017 Advanced planning As Chair I have completed the WBS survey, requesting: Attendance for ~10 people. No preference for date, meet on any two days. Flexible about days. Joint meeting with CSS WG and with Web and TV IG. Avoid overlap with Web and TV IG. Permit observers. Not member confidential. Estimate ~6 attending technical plenary. Estimate ~3 attending AC sessions Tuesday and Thursday. https://www.w3.org/2017/11/TPAC/Overview.html Chair was asked for further clarification about the joint meetings and the overlap avoidance; since Web and TV IG are likely to meet on the Monday, and CSSWG on the Monday and Tuesday, I requested Thursday and Friday for the main TTWG meetings with joint agenda slots with the other two groups on Monday and/or Tuesday.

Please review the ED and any open pull requests with publication as WR in mind; the intention is to publish by June 30. Aside from resolving group review issues generated during this review period, (i.e. those required to achieve consensus on the proposal to publish) no further changes will be accepted. At the moment of writing this agenda, there are: * 2 open issues on the Editor's WR Work List milestone, of which 1 is not labelled as "PR Open"; * 50 open issues with no milestone, all of which have no PR, and * 7 open issues awaiting some feedback on disposition, which are in the "Group's WR action required list" milestone.

Issues Iterate through open issues with no PR – decide action to take on each, e.g. defer to CR, defer to TTML.next, close etc. If there are any issues that we decide need to be resolved before WR a proposal for the fix is needed ASAP (basically, it's too late already unless it can easily be agreed by the group). Collate list of the issues we want to open with CSS WG We need to put this together as part of the agenda for a request to meet at TPAC.
