Agenda

• (standing item): documents on track
  • RFC
    • VOEvent-2.1 - TCG:done
    • MANGO-1.0 - TCG:done
    • DALI-1.2 RFC page: RFC nearly empty
    • DocRegExt -1.0 - TCG:done
  • EN
    • DataOrigin-1.2: PEN ( PEN doc): status & discussion
      • Received feedback from 3 people, mostly editorial, including an updated provenance graph.
      • No blockers for this, but we should clarify moving forward the document process for ENs, e.g., where to share feedback
  • Errata
    • any?
  • VEPs
    • any?
  • PF ffedback on drafting new HiPS doc: Difficult to build document on Windows. Docs seem a little out of date. Maybe can file some issues on ivoatex.

• IVOA June 2026 Interoperbaility Meeting

  • program page: https://wiki.ivoa.net/twiki/bin/view/IVOA/InterOpJune2026
  • program setup: https://wiki.ivoa.net/twiki/bin/view/IVOA/ProgramPrep2026A
  • send out calls
  • propose sessions
  • remember to register (if you plan to attend and haven't done so yet)
  • CSP driven sessions
    • Science Platforms: 4 confirmed speaker + 2 invited
    • AI & archives: 1 confirmed + 3 potential
  • Request from CSP for DAL and DM to have a joint session on spectral support
  • JE: Would like to follow up on High Energy progress. Perhaps a joint session to get others involved? DM/DAL? Maybe Apps too? This can help show how DMs are useful.
    • The audience seems large, so a plenary makes sense, so we should reserve one.
  • JS: One session for DSP should be fine
  • GL: One for DCP
  • TC: Likely one for Ops

• report on current activities, plans from here to June
  • MCD - Working on documenting implementations for Transform model to be ready for full RFC
  • JR - Is gathering list of names interested in coming up with a VOEvent 3.0. Pleased with list so far from several communities. Feedback is that they are happy with flexibility to move beyond the XML transport standard. Will get a meeting together to kick off the effort.
  • MM - What are DSP standards that need updating? Any plans there?
    • JS - Working on authN using tokens. Federation is a known question but have not been talking about it so far. Software discovery service could be interesting.
    • MM - Maybe revamping VOSpace as well?

• IGs & TCG/CSP interfacing (draft idea here: https://yopad.eu/p/IVOA_IG_ToR_proposal-365days): contribute (e.g. by email to me)
  • Of course this is an Exec issue, but would be informed very much by TCG input. Reminder to think about this and add your ideas. Can have follow-up discussions at Interop.

• how to handle priorities and activities besides documents on track and roadmaps
  • Reminder to think about this and make suggestions.

• other topics
  • positions still TBF
    • Radio IG vice-chair role is open
      • JE - Could SKA help with this?
        • JS - Difficult to find someone with time. Implementation of science platform is getting priority. Partly a marketing problem; i.e., there can be a mutual benefit
      • MM - Has not been successful working with Australian side of SKA.
    • Edu IG vice-chair: open but something is moving
  • Coordination roles reaching nominal deadline
    • Registry, DCP: no extension
    • DM, DSP, Semantics, TD (deputy), Operations, SS (deputy), Radio (chair): extension possible
  • Please let us know of your ideas for these roles
  • new website: it is there, time to start renovations on content
    • See https://github.com/ivoa/IvoaDocViewSite for technical details
