    • How to write registry record
    • Q from Baptiste: (Not just registry, but) how can we track the usage of terms? Some may not be being used, but can we really know?

    • curation of telescpope instrument
    • DOIs for Vizier

  • SSIG:

  • TDIG: Rafael cannot continue as chair. Pierre F will stay on as vice chair. Looking for new chair.

• schedule w.r.t roadmaps (cherry picked) comparison
  • frequency axis MOC -- No recent work towards standardization
  • P3T impact on DAL roadmap -- TAP
  • DAP -- Some light discussion on cone search
  • LineTAP? -- Need second impl., Definitely open questions. SLAP is dead? Maybe reture LineTAP as well, or freeze it until it's shown to be used. Stay tuned.
  • Observational Facilities vocabulary -- covered in sematics
  • IHDEA connection
  • UCD as a vocabulary
    • Do we need to change the vocab representation?
    • Since we are rebuilding the website and the document repository, what about vocabs? (see https://www.ivoa.net/rdf/).
    • Process is git pull, make install builds the statis file for the website. Happens through ssh tunnel to do the web page updates.
      • Suggestions about alternatives such as github actions (or other CI techniques). No conclusions.

• news to consider
  • ASDF
    • impact/usefulness w.r.t. IVOA
      • how different from FITS friendship
      • externally managed standard (sw based one)
        • collaborate and try to contribute towards a community standard
        • envision future "EN-like" connection/binding (why would it be different than the .parquet case? what did we do for HiPS?, ...)
  • Comments:
    • Don't have a data model for the metadata
    • It's an external standard, so we don't want it internally.
    • Our interest seems to be primarily in the metadata.
    • Maybe what we want is mapping the metadata we manage to what can be represented in ASDF (and other formats).

• open topics/actions
  • astronet.ru publishing registry issue
    • In July we were told 3-4 month delay. Last news is that problem is not resolved, but may be by the end of the year.

    • Marco will put renaming to exec.

• AOB
  • Janet will be formally asking exec for High Energy Interest Group
