Timed Text Working Group Teleconference

<scribe> scribe: nigel

This meeting

Nigel: Today, our agenda has TPAC F2F for next week, TTML Profile Registry,
... and proposing that we request transition to Rec of TTML1 3rd Ed, TTML2 and IMSC 1.1.
... I'd like to check if there's any review response of the CSS email also.
... Any specific points to raise or other business?

Andreas: Not from my side.

Glenn: Negative!

Pierre: Only got a couple of minutes
... Re the CSS Text Level 4 changes, no comment - it's hard for me to understand but good that it's there.
... Maybe with a greater understanding of CSS it makes more sense.

Transition requests

Nigel: I've reviewed the open pull requests to prepare Rec versions, I think they're all
... approved now.
... I had one query about the list of contributing authors on TTML1 3rd Ed but aside from
... that there are no substantive changes.
... As mentioned last week, I propose that we begin the decision review period on a resolution
... to request transition to Rec of TTML1 3rd Ed, TTML2 and IMSC 1.1 today.
... This would be based on those repo branches that contain the prepared versions.
... Thank you to the Editors for creating those.
... Any objection to requesting transition?

group: [silence]

Nigel: Our timeline shows I have to send the WG Resolution on 2nd Nov.

PROPOSAL: Request transition of TTML1 3rd Ed to Rec on 2nd Nov 2018
... Request transition of TTML2 to Rec on 2nd Nov 2018
... Request transition of IMSC1.1 to Rec on 2nd Nov 2018

Nigel: Any objections to making those Resolutions?

group: [silence]

RESOLUTION: Request transition of TTML1 3rd Ed to Rec on 2nd Nov 2018

RESOLUTION: Request transition of TTML2 to Rec on 2nd Nov 2018

RESOLUTION: Request transition of IMSC1.1 to Rec on 2nd Nov 2018

Nigel: Thank you!
... Looking at the AC review there are no objections, and 11 organisations have responded.

Glenn: You might want to point out the change request on the wiki, which drove a
... number of the changes. Terence Eden is probably not aware of it and we didn't refer
... to it.

Nigel: I got the sense that he thinks it is good practice to motivate the changes, and we
... have not done that.
... I am happy to check that with him though.

Glenn: It would certainly help for people reviewing from the outside in, you know.

Nigel: Agreed.

TTML1 Contributing Authors

Nigel: Looking at the TTML1 list of Contributing Authors, I think it needs some
... adjustment. I think I should be added, and Andreas's status is no longer Invited Expert.

Glenn: I think we should update it as you mention to add yourself and update Andreas
... as a minimum.

Pierre: No opinion

Glenn: Pierre, can you handle that update?

Pierre: Sure.
... Can people be listed in Editors as well as Contributing Authors?

Glenn: I did that in TTML2

Nigel: No objection from me

Pierre: If you can open an issue for it that would be helpful, or make a comment on the PR

Nigel: I can do that

Pierre: It would be useful to say the list should match TTML2

Nigel: Yes, that's fine.
... I will update the pull request comment
... Any other comments on the Rec preparation pull requests?

group: [no other comments]

TTML Profile Registry

Nigel: I've opened some pull requests but there are some issues remaining without
... proposals.

Pierre: My understanding is Mike wanted to be involved but cannot be until after TPAC.

Nigel: That's right.

Pierre: I haven't done anything because Mike seemed interested in doing it.

Nigel: We have a scheduling issue - if we want to publish on 13th Nov then we need to
... complete it on October 30th. I have mentioned that to Mike.

Glenn: We can publish the Note later.

Nigel: Yes, I was thinking that from an external perspective it makes sense to synchronise
... its publication with the Rec publications.
... Our decision policy does apply.

Pierre: I think we should make sure Mike is informed of what we're planning.

Nigel: I think I already did, but if it's not clear then we can make it so.

Pierre: I thought it was not clear.

Nigel: Can we agree to target 13th November for publication of an update?

Pierre: If its available 2 weeks later and Mike is happy then it's a better outcome. If he's
... happy for us to proceed and make Nov 13th then I'm equally happy with that.

Glenn: I don't have a strong position either way. I have no problem deferring to let Mike
... get involved and in some ways would prefer that.

Andreas: No opinions

Nigel: It seems to be me who has the strongest view, and I also would like Mike to be
... able to participate and be happy with the outcome.
... The key thing is there doesn't seem to be a strong group motivation for publishing
... on the same date as the Recs, so we can take a little longer.
... I will contact Mike and let him know.
... Moving on,
... The EBU-TT Metadata proposal is in pull request #50. Unless anyone has any comments
... now then I propose that we review this in our f2f meeting next week.

Pierre: I've not had time to review, maybe tell us the general idea.

Nigel: I made a proposal based on Cyril's suggestion, which involved adding both a
... normative statement about the origination of the ebuttm: namespace and the elements
... we refer to within that namespace, and an informative note describing the applicability
... of the EBU-TT Metadata specification, which was drawn from the abstract and scope
... of that document. However my concern is that I don't think that text is ideal. So I'd
... appreciate reviews.
... I took text from the specification to be non-contentious but the result somehow
... doesn't hit the spot.

Pierre: Thanks for that, I will review it.
... I have to drop off the call now. [drops off the call]

Nigel: Thanks.
... There's one other thing to add, which is that specref isn't up to date for the EBU
... specifications so I've added local bibliography entries in the pull request and will also
... make a pull request on specref to add them there; assuming that works, I can remove
... the local entries from this pull request.
... I'm mid-flight in preparing the specref pull request right now.

TPAC 2018

Nigel: There's been some discussion of the agenda for the M&E IG joint meeting, and no
... more on our meeting.
... As per the discussion above I will add TTML Profile Registry pull request reviews to
... the agenda for our meeting.
... Any queries or comments for our TPAC agenda or our joint meeting agenda?

group: [no]

Nigel: We'll finalise the agenda on Monday morning in any case.
... One thing to note - our meeting on Monday begins 0830 and I hope to be there from
... the beginning.
... Please try to be punctual so we can maximise the use of our time.
... I have also sent Webex joining details to the member-tt reflector for anyone wanting
... to join remotely, and we have a Polycom phone available in the room.

Meeting Close

Nigel: We've completed our agenda, so thank you everyone. See you on Monday, those
... at the F2F, good travels. [adjourns meeting]
