<nigel> Topic: ARIB incoming liaison
<nigel> -> https://lists.w3.org/Archives/Member/member-tt/2020Apr/0000.html ARIB incoming liaison
<nigel> github: https://github.com//issues/116
<nigel> Nigel: Is there anything we can action in IMSC 1.2 or requirements for v.next?
<nigel> Pierre: The easy one is character set but that is a normative part of IMSC so we can't
<nigel> .. easily do it in 1.2. I think this came too late to deal with in IMSC 1.2
<nigel> .. We should probably do the character set one at some point - that seems like low hanging fruit.
<nigel> .. The rest: it is hard to understand if it is an encouragement to try to seek convergence
<nigel> .. or just some input that says "we're already doing this, you might want to". It is unclear.
<nigel> Andreas: Yes, and it would be important to find out.
<nigel> .. If they have an interest in convergence then it would really make sense to build a liaison
<nigel> .. with a common goal, but that's a big question.
<nigel> Pierre: It is also really formal. Thinking out loud, TTWG could try to find a way to have
<nigel> .. a more interactive discussion. Is this an invitation to seek convergence on a future
<nigel> .. version of IMSC in ARIB B62 or is this just input for TTWG's benefit only.
<nigel> Nigel: The easy thing is to ask them, to respond with a liaison to say thank you,
<nigel> .. we can't do this in IMSC 1.2, but we could in IMSC 1.3 and what is their timeline.
<nigel> Andreas: Yes, sounds good but we all know liaison process can be very slow.
<nigel> .. I propose to consider what Pierre said and try a less formal way to have a conversation,
<nigel> .. maybe with the Chairs or Editors, to get a feeling what is the way to go. That may help.
<nigel> Nigel: OK that sounds like a good idea, I can try to use the contacts I have.
<nigel> Pierre: Maybe the formal nature of this suggests they want to know it is being taken
<nigel> .. seriously. Maybe a formal invitation to collaborate with W3C would help. I've seen something
<nigel> .. like this before. Maybe that's their expectation, and the answer would be different
<nigel> .. if W3C invites them to collaborate rather than individuals talking. Food for thought.
<nigel> Atsushi: I fully agree that this is a quite formal comment and with this statement.
<nigel> .. Maybe a formal reply and conversation is their intention.
<nigel> Nigel: I think I need to think about this more.
<nigel> Pierre: Has there been formal collaboration between W3C and ARIB in the past?
<nigel> Nigel: I do not know.
<nigel> Pierre: Atsushi, maybe you could look into that, maybe asking the staff if this has
<nigel> .. happened in the past.
<nigel> Atsushi: For now I can only say that there is a liaison relationship between us and them,
<nigel> .. so in any case we can communicate to them about that.
<nigel> .. For some case I need to dig out something.
<nigel> SUMMARY: Discussed in call today, Chairs to consider potential next steps, @himorin to look into history of collaboration with ARIB and W3C.

[himorin]

Only found one example in the past, and also I've got suggestion as (similar to what was written in an example):

• no formal action is necessity
• add comments into GitHub issue for tracking (as usual discussion and tracking)

should I file issues to imsc repository for the reply?

[nigelmegitt]

As discussed on today's call (#111), @himorin or @palemieux to open issues on the w3c/imsc repo for each of the comments raised by ARIB in their liaison, for our discussion prior to writing a liaison message back.

[nigelmegitt]

Thank you @himorin for raising the issues on the IMSC repository directly. The next step is for us to discuss those issues before responding back to ARIB.

On the basis that all other actions are now logged as separate issues, I'm closing this.
