Actions

• NEW - (ALL) brainstorm within groups about contributing to the data model usage hack-a-thon/workshop proposal (OPEN but postponed)
• NEW - put issues on DocStd git repo and works towards a F2F meeting with TCG (interop?) (ongoing?)

Agenda

• Review actions

• (standing item): documents on track
  • RFC
    • VOEvent-2.1 - RFC page
      • status and proposed path forward

PF: Can we just cite existing 2.0 implementations since the changes are just vocabulary?

BC: Should be able to use 2.0 implementations, but we don't have s/w that parses and validates 2.1 yet.

MD: Part of this is for discovery, so part of the implementation should prove that that part works. The new extensions should be exercised in the implementations.

BC: Agree and think PL may have before the interop.

JF: Can write a validator.

We will take stock at the interop.

• • • StandardsRegExt-1.1 RFC page: REC as of 2025-10-20. Thanks everybody!

• • • MANGO-1.0 RFC page: status?

DALI

• GM: Expect new RFC for DALI before interop

• • EN
    • any?

MM: Need to upload the proposed note (make upload), then e-mail TCG.

MD: Shameless plug: if you're doing ivotex, skim http://ivoa.net/documents/Notes/IVOATexDoc/ to get an idea what it can do for you...

JE: HE note is maturing. Probably ready by end of year. May we ask for prelim review without implementations.

MM: Definitely can ask for feedback on appropriate mail lists (TCG, Interop)

MD: Semantics with DAL-Reg is a concern.

SD: Maybe Semantics only needs 1 session (based on current proposals)

No clear solutions. Let's keep as is and see what the final demands are.

AD: Apps may not be full, so maybe could be joint with another group.

MM: Please provide info by Monday on final needs and conflicts. Ideally, would like to avoid WGs clashing with each other. SS contributions so far?

MD: Not sure yet about level of SS contributions. May be candidates for joint session.

• • feedback and finalise by the start of ADASS
  • maybe a last announcement (registration deadline is in 2 days)?
  • TCG attendance: only a few missing!
