standards on the recommendation path

• DataLink-1.1
  • WD progressing, new WD release (Q3-2021) after closing a few Pull Requests
    • this might set the line for v.1.1
  • RFC by Autumn Interop
  • further issues/features identified already for subsequent revision
• ADQL-2.1
  • Ready for Proposed Rec (Q2 2021)
  • RFC opening soon
  • REC by Autumn Interop
• DALI-1.2
  • multipolygon still pending
  • otherwise ready for PRec+RFC (Q3-2021)
• ConeSearch-1.1 [in connection with TD IG]
  • work will progress to close issues
  • a new WD before Autumn 2021 Interop
• ObjVisSAP
  • PR-1.0 nearly there
  • implementations ready, RFC should be possible by Autumn Interop
• ProvTAP
  • continues work towards mature WD status (by Autumn Interop)
• TAPRegExt [in connection with Registry WD]
  • Now in GitHub repo
  • WD release in Q3/Q4-2021
• SIAP-2.0 / SODA-1.0
  • Now in GitHub repo
  • work on new WDs based on existing feedback (WDs by 2021 Autumn Interop)
• EPN-TAP [DM WG connection]
  • Validator being prepared
  • Some tidy-up expected after validator work
  • Should move to RFC in Q3 2021
• ObsLocTAP [managed by DM WG]
  • RFC for PR-1.0 priod closed. Should move to REC by end June
  • Proposed for endorement at IAU General Assembly in August 2021

• SLAP-2.0 -> LineTAP solution
  • preliminary internal (to authors) WD
  • progress expected to be reported at Autumn 2021 Interop
• SSAP -
  • Spectroscopy data access could potentially lead to new minor revisions in advance of any integration with a more general SIA2
• ProvSAP (idle)
• Following Radio IG, TD IG activities for requirements
  • refer to the roadmaps of these IGs for details
• file-oriented catalog data access: start of discussion on Parquet

Data Model WG

Grid and Web Services WG

Registry WG

Semantics WG

The Semantics WG hopes to get the UCD list 1.4 approved by the TCG early in the semester; it has been ready content-wise for quite a while. We will then start work on the UCD list 1.5, for which some statistical terms are already in the pipeline.

For SimpleDALRegExt 1.3, we will try to get the http://www.ivoa.net/rdf/refframe and http://www.ivoa.net/rdf/product-type vocabularies into shape. The first is also necessary for Coords in DM, for the second we will take care it will remain topical and useful for its original source in Obscore.

For VODataService 1.2, we will accompany the acceptance process for the http://www.ivoa.net/rdf/messenger vocabulary, working with the SSIG to see if additional messengers from the are already required.

With Vocabulares 2.0 now passed, we will work with Registry to get the note on adopting the UAT as an IVOA vocabulary endorsed and then produce an Erratum to VOResource 1.1, explaining how to actually apply it in VO resource records.

We hope to publish a first draft of a vocabulary of object types in June. This will reflect the current state of SIMBAD's work on updating their object classes.

Somewhat more remote is a vocabulary of instruments and facilities (where it is not unlikely that we will find that this goes beyond what vocabularies should reasonably do). If it is feasible, it would provide interoperable identifiers for such entities (e.g., for the VOResource elements and the respective fields in SSAP, SIAP, or Obscore), as well as pointers to names and identifiers them in legacy lists.

Data Curation Preservation IG

Education IG

Knowledge Discovery IG

Operations IG

• Software Identification:
  • SoftID Note was published as NOTE-softid-1.0 just after May Interop
  • Encourage and monitor service and client takeup
• Tackle non-compliant services:
  • Support service operators to use validation and improve services
  • Update validators as required
  • Chase up common/persistent issues
• Provide feedback on standards
  • Continue to work with DAL to feed back operational experience to standards update/development
• Ongoing activities:
  • Monitor VO health (conformance, reliability, performance)
  • Curate IvoaValidatorsSummary
  • Provide forum for ongoing discussions
• Schedule occasional telecons as required. Possible topics:
  • Non-compliant service review and activities
  • DAL/Ops standards feedback (and what to do about it)
  • Validator developments

Radio IG

• Implementation Note posted to GitHub

• ObsCore extension for radio data under discussion

Solar System IG

Theory IG

Time Domain IG

On coverages

• MOC2.0 WD: 2 implementations and validator - RFC (TD & Apps)
  • Info collected under: https://wiki.ivoa.net/twiki/bin/view/IVOA/MocInfo?
  • Everyone is welcome to comment under https://github.com/ivoa-std/MOC
• Use of Time-Frequency Catatalogs for by solar & planetary radio science - evaluate/ investigate further on the extension of MOC to add frequency / energy / wavelength (TDIG & SS & Radio IGs)

• FRBCat and TNS - follow-up on the possibility of adding a TAP service (TD & Radio IGs)
• Data Central’s Data Aggregation Service to quickly inspect FRB candidates - Follow-up on time series explorer (TD + DAL)
• Astro-COLIBRI - follow-up on usage of IVOA stds where possible, e.g ObsLocTAP, ObjVisSAP

• ObsLocTAP - follow-up on status

• Note under: https://github.com/ivoa/TimeSeriesDiscoveryAndAccess
• Update to include the SSA - keeping in mind the std is likely to evolve in the near future (TDIG & DAL)
