On the UCD end of things, we are hoping to have a PEN for version 1.5 of the UCD list ready for TCG review by early 2022. This will include a few statistical concepts, and possibly MOCs, projection and a means to identify oscillation periods from other periodic phenomena; there is also a generic concept for PIDs considered. See https://wiki.ivoa.net/twiki/bin/view/IVOA/UCDList_1-5_RFM for details.

Also regarding UCDs, we will prepare two Errata (to SSAP and SLAP) regarding malformed UCDs used in these standards.

For SimpleDALRegExt RFC, the vocabulary http://www.ivoa.net/rdf/refframe is under review; we believe it is largely in shape.

This cannot be said for http://www.ivoa.net/rdf/product-type, which is up for adoption by Datalink. We will provide a new prototype based on SKOS before the end of 2021 and evaluate whether it better fits the use cases envisioned.

We have also produced a draft of a vocabulary of object types at http://www.ivoa.net/rdf/object-type. There is no fixed schedule on which this should be evaluated and developed, except that having it for the next revision of obscore would clearly be very useful.

Also, we should revive the process of getting the note on the adoption of the UAT as an IVOA vocabulary endorsed by the TCG.

Operations IG

• Tackle non-compliant services
  • Review specific items noted in Nov 2021 Euro-VO Registry Weather Report
  • Chase up common/persistent issues
  • Support service operators to use validation and improve services
• Develop/maintain/curate validation tools
  • Ensure validators are available for all standards (esp. during REC process)
  • Pursue automatic invocation capability for validation tools
  • Understand discrepancies between different validators
• Work with other WGs:
  • DAL: monitor follow up of issues reported May 2021 (in progress)
  • Semantics: monitor UCD/VOUnit compliance changes since report Nov 2021
• Ongoing activities:
  • Monitor VO health (conformance, reliability, performance)
  • Provide forum for discussion of operational issues
