Glenn,

We have introduces a decision policy in our charter

https://www.w3.org/2018/05/timed-text-charter.html

"to afford asynchronous decisions and organizational deliberation, any resolution (including publication decisions) taken in a face-to-face meeting or teleconference will be considered provisional. A call for consensus (CfC) will be issued for all resolutions (for example, via email and/or web-based survey), with a response period of 10 working days. If no objections are raised on the mailing list by the end of the response period, the resolution will be considered to have consensus as a resolution of the Working Group".

I don't see that it only adresses substantive changes.

We may overrule this, if the WG is OK.

And we could have a WG resolution to move to PR during the CR Review Period (guessing we won't have any comments to deal with).

For example for TTML2;  CR publication is 14/08/2018, end of review is 11/09/2018 and PR transition request is targuetted on18/09/2018.

We could have WG resolution for PR publication on 04/09/2018, (leaving 14 days before the PR transition request).

But that would be before the end of review, a resolution that could be based on a document which could change, if edits are made after .

Maybe a discussion during the call today would be best.

Keep in mind that we can make editorial (non-substantive) changes throughout the CR periods. Also, I'm not sure what CfC would be required prior to a PR transition if the WG is satisfied that only editorial changes have been made. Are you suggesting a CfC because you think it likely a substantive change will be required? And, if that were the case, wouldn't we be forced to start a new CR?

For TTML2, I will strongly oppose any substantive change during CR3. If some issue comes up that requires a substantive change, then I expect we would postpone its resolution to TTML2 2e.

Hi,

I have prepared a timeline showing the expected publication dates of IMSC 1.1,TTML1 3rd Edition, TTML2

It shows publication dates for  CRs, PRs and Recs, and  also showing  WG task ( transition requests, final draft, implementation report, CfC, etc,   see attached sheet. (Note that dates in red are dates from the "174 days to Rec" Tool.

The shortest  REC publications dates, based on the this Tool are as following  (see the  sheet  with tab "Timeline without CfC" in the attached xls file).

- TTML2 REC publication: tuesday 30 oct 18
- TTML1 REC publication: tuesday 30 oct 18
- IMSC1.1 REC publication: thursday 11 oct 18 (or we can synch with tuesday 30 oct 18)

Note that these timelines are very very tight and are the MINIMAL the group can expect (only taking into considerartion the W3C process), not the WG extras time.

It is more than likely we will meet extra delays (implementation reports, testsuite, edits to be done for PR and maybe trigering a CfC, and eventually edits to be done for REC based on AC review.

Therefore, I have drafted another Timeline adding a 14 day CfC period before requesting transition to PR, for each Timeline spec

(see the  sheet  with tab "Timeline with PR CfC" in the attached xls file).

This CFC introduces the following REC dates

- TTML2 REC publication: tuesday 13 nov 18
- TTML1 REC publication: thursday 8 nov 18
- IMSC1.1 REC publication: tuesday 30 oct 18

We can discuss this timeline during our call today and impact  with MPEG contraint.
