  • Couple of bigger topics/actions from discussions for TCG/IVOA to tackle:
    • Major breaking changes to IVOA standards - How to handle??
  • Mtg attendees were happy that the HEIG was accepted as a IG at the Interop meeting; no further highlights were added.
• 2025 Roadmap - collection of items and definition (all)
  • Pointer to Roadmap from TCG: https://wiki.ivoa.net/twiki/bin/view/IVOA/2024BRoadmap
  • Topics to start discussion with:
    • VOEvent - Follow-up IG meeting (1/9) summary - Did anyone attend?? -- Found these notes
    • Obscore - Ian's IVOA presentation; HEIG_obscore_summary.pdf
      • Summaried briefly; received email from FB just before meeting with feedback/comments; topic for next focus mtg
    • Data Models - Bruno's IVOA presentation
  • Consensus was that Obscore would be our primary topic before the May Interop; we will have a topical meeting in the next few weeks to discuss
    • For the DL3/L1 (event list + IRFs):
      • Ian's HEIG_obscore_summary above is a good review start, see also Mathieu's talk in Sydney (here)
      • Mathieu: the use of DataLink as mentioned in our note should be experimented
    • For the DL5+/L3 (astrophysical products, and catalogs):
      • Laurent Michel reminds that the XMM catalogues discoverability uses MIVOT/MANGO
      • Janet reminds that ObsCore is used for the Chandra catalogues
      • Needs to address this point and try to converge towards a common solution in preparation of the venue of the future CTAO catalogues
• Organization of HEIG - Monthly meetings, Next Hybrid meeting (Bruno) - Folks agreed with ~monthly meetings and topical meetings as needed.
• Thematic remote meeting: Obscore extension proposal by Patrick Dowler (see Janet's email of the 01/06/25) (Bruno) - Agreed, There's a poll out as of 1/29 to schedule this meeting.
• AOB
  • We got a paper from Michele Doro (12/13/24) to review. - MAGIC_DL5_data_portal_v20250201.pdf
    • This is a good paper that outlines the data distribution and headers of data; pulls in VO & IVOA; discusses the data model and Obscore.
    • I think should be reviewed as HEIG works through it's priorities on these topics.
