Description
The Unified Astronomy Thesaurus (UAT) provides a comprehensive,
interlinked set of concepts relevant for astronomy and astrophysics using
SKOS. It is taken up in the Virtual Observatory at least for registry
subject keywords. For various reasons, it is desirable to have the UAT
available subject to the constraints laid down in the IVOA Vocabularies
in the VO 2 specification. This Note describes the rationale and the
details of the UAT adoption by the IVOA.
