Difference: IvoaSemantics (97 vs. 98)

Revision 982021-05-07 - MireilleLouys

IVOA Semantics Working Group

The Semantics Working Group (Charter) superseded the UCD Working Group in 2006 as it was realised semantic resources beyond UCDs were required. To this day, the main focus of the Semantics WG is the maintenance and development of Vocabularies.

The WG is an open association communicating via our mailing list that you are welcome to subscribe to. We also host roughly bimonthly SemanticsCalls, which are open to all interested parties.

The group is managed by

WG Chair MarkusDemleitner (2019-)
WG Vice-chair CarloMariaZwoelf (2019-)
WG Chair emeritus MireilleLouys (2015-2019)

Former work

Items here are occasionally moved to UCDandSemanticsFormerWork.

Towards Vocabularies 2

In preparation to the effort of modernising the Vocabularies in the VO specification, a page was set up to try a comment process for updating the datalink vocabulary, UpdateDatalinkTerms. While this should no longer be used for discussion, the proposals and comments are for now kept for when they will enter a new-style process.

Also, VocabularyTestPage was a now deprecated effort to provide the vocabulary index now on http://www.ivoa.net/rdf.

New UCD List v 1.3

Elaboration of new UCD keywords for planetary metadata and radio data. This effort is described on the discussion page PlanetaryUCD .

This has generated a loop for revision for the UCD list of terms , now in the final step of Recommendation.

See http://wiki.ivoa.net/twiki/bin/view/IVOA/UCDList2017RFC for the request for comments for http://www.ivoa.net/documents/UCD1+/20170831/index.html.

Units specification in the IVOA

VOUnits: This specifies how to express unit strings in VO documents, APis, protocols and interfaces.

  • The VOUnits document is now an IVOA REC. The VOUnitsRFC and DiscussionOnVOUnits pages still exist, but should not now be added to.
  • There are no immediate plans for further work on the standard, however there is a small collection of issues and suggestions at VOUnitsNext
