---++ Agenda

   * (standing item): documents on track
      * RFC
         * VOResource-1.2 - *approved 2025-04-06*
            * *This is approved, buy more feedback came in during the exec approval. That is not the normal process, but we don't want to ignore the input, so proposed to have a rapid-turnaround update and release for 1.3 limited only to the late feedback.*
               * *Markus: One point was "why do you only allow DOIs as alt identifiers", so maybe not worth a release. A couple minor points being addressed in a PR address some other minor points. A response to other comments explaining why documentation changes are not needed should complete the updates.*
               * *Tom: Can we find a way to quickly release 1,2 now as voted on and approved, then quickly release a 1.2.1 in an erratum-like process?*
               * *Markus: Given tagging and version control capabilities we have, we could release new version instead of errata. Maybe just bake in the errata but don't bother with the minor rev.*
               * *JJ, Do the errata not get baked into a new copy of the doc? Why not?*
               * *Markus: We didn't have the infrastructure for that, but with ivoatex and github we do now.*
               * *Conclusion: Let's just notify exec of the new updates and ask for reapproval. Updates to DocStd to bake in errata to the doc can happen at a comfortable pace. Marco to take the lead.*
         * VOEvent-2.1 - status check
         * StandardsRegExt -1.1 - status check
      * -no- EN, Errata, VEPs

   * update RFC template: https://wiki.ivoa.net/twiki/bin/view/IVOA/TemplateRFC
      * usage and feedback
      * *RFC Template has been updated. Please start from there with new RFCs.*

   * Roadmap 2024B

   * June Interop planning
      * who is planning to be there in person/remotely?
         * *Please notify Marco, Francesca, Tom of your attendance and whether it is in-person, especially for Sunday.*
         * *On the exec, we have heard that Marco/INAF will attend, ESAC will send some, China will send 2. CDS will not send anyone, and probably not much from France.*
         * *Please register as soon as possible. Will send a reminder pretty soon but not right away.*
         * *Some people will only attend a subset of sessions. Send Marco requests for specific requests for remote attendance of specific sessions.*
      * web page: https://indico.ict.inaf.it/event/3121/
         * registration: https://indico.ict.inaf.it/event/3121/registrations/1444/
         * call for abstract: https://indico.ict.inaf.it/event/3121/abstracts/
            * *This general call for abstracts is new based on feedback from the last meeting to make the call for participation a little more open.*
            * *Please send out a call for participation to your groups.*
      * wiki page: https://wiki.ivoa.net/twiki/bin/view/IVOA/InterOpJune2025
      * planning page: https://wiki.ivoa.net/twiki/bin/view/IVOA/ProgramPrep2025A
         * *Add planning notes, session requests, etc. here as it comes up so that we can start drafting a program.*
         * *Local and CSP will be combined plenary dealing with NASA missions and data challenges.*
         * *DM will request at least 2 sessions*
         * *DAL, probably 2*

   * Data Models organisations
      * open discussion (based on Mark CD report at the last TCG)
      * *Mark- Two main options:*
         * *Take the approach of building block models (that are not necessarily useful on their own), what are the implications to documents, maintenance, etc.*
         * *Use case based models. They may overlap quite a bit.*
      * *Marco: This relates also to the questions about what constitutes validators and interoperable implmentations*
      * *Markus: Favors modular approach, and implementations are easier with <a data-wikiword="PyVO" href="https://pyvo.readthedocs.io/en/latest/" target="_blank">PyVO</a>*
      * *Mark: <a data-wikiword="PyVO" href="https://pyvo.readthedocs.io/en/latest/" target="_blank">PyVO</a> and Laurent's work really help with the implementations, but also relied on quite a bit of work and help.*
      * *Gilles: Many times I just need a small part of the model. This was the idea of MANGO*
      * *Adrian: Parallel with s/w dev where you want to separate out different pieces. With s/w/dev we have tools and so on to test the impacts of changes throughout the dependency chain. How do we handle that with standards?*
      * *Mark: Good analogy.*
      * *Marco: Maybe this brings up a broader discussion about RFC processes...*

   * Other ongoing activities / Open topics
      * Major version transitioning in Registry
      * astronet.ru publishing registry
         * *Need to wait a few more months*
      * TD IG chair
         * *Good news pending*
      * statistics on clients (agents) for TAP (and other protocols): OPS/DAL/Apps
      * GWS -&gt; DSP name changes
         * *Name change can be handled by admin at ivoadoc, but requires stopping mail servers for part of a day.*
      * IVOA static website rebuilding
         * *Before interop, the new website will replace the old one*

   * AOB
   * Date for the next TCG vconf
      * proposed: -- *5-7 May 2025 @ 13:00 UTC* -- consolidate topic and evaluate schedule status, after Exec vconf & plan topics for the in person TCG
         * *May 5 would not be good for some.*
         * *Pencil in Tuesday, May 6. Mention conflicts via e-mail if needed.*
      * and the subsequent *21-23 May 2025 @ 20 UTC° _IF NEEDED_: finalise program
