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The Semantics Working Group ( Charter) superseded the UCD Working Group in 2006 as it was realised semantic resources beyond UCDs were required.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 (see also ProgrammingWithVocabularies).

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

Current Activities

• Vocabularies in the VO – Vocabularies-2_1-Next
• VOUnits – VOUnits-1_1-Next

Other documents would have to have their sources unearthed and ported.
