CURRENT FOCUS
- Work towards adoption of PR VOResource-1.2 (in RFC from 2024-11-17)
  - https://wiki.ivoa.net/twiki/bin/view/IVOA/VOResource12RFC
- Investigate "Serving Simulated Data in VO Services/Collections"

  - Open question: reuse SSAP datasources for VODataService ?
- Support data publishers towards filling coverage information as MOCs in publishing registries according to REC RegTAP-1.2
- Participate in "alternative links" in DataLink effort with DAL WG to publish cloud-based data products cf https://github.com/ivoa-std/DataLink/issues/117. Also investigate with GWS WG if necessary to have such metadata in the Registry.
- Prepare future RegTAP-1.3 to facilitate searching by product type served after VODataService-1.3

STANDARDS IN PROGRESS
- VODataService-1.3 (editor: MD) "A VOResource Schema Extension for Describing Collections and Services"
  - https://github.com/ivoa-std/VODataService
  - Status: WD https://ivoa.net/documents/VODataService/20241113/index.html
    - adding a productTypeServed element child to to DataService
    - working on mechanism to discover simulated data
- DocRegExt-1.0 (editor: MD) "Educational Resources in the Virtual Observatory"
  - https://github.com/ivoa-std/DocRegExt
  - Status: WD https://ivoa.net/documents/DocRegExt/20230426/index.html

  - Status: WD https://ivoa.net/documents/StandardsRegExt/20240125/index.html

CONTINUOUS WORK
- Implementation: Continue developing and maintaining the new PyVO Registry search and discovery API
- Curation and Validation: setup a hackathon and project board to correct Registry issues at College Park Interop in June 2025
- On-boarding Effort: Prepare and fund a workshop to discuss and disseminate best practices for registry publishing
- Continue discussions on “Linking capabilities with tablesets” (cf https://wiki.ivoa.net/internal/IVOA/202404InteropRegistry/InterOpMay2024Reg_linking_capabilities_tablesets.pdf)
- Continue involvement with DCP IG, esp. on the note “Data Origin and the VO” https://www.ivoa.net/documents/DataOrigin/
