IVOA Vocabulary: VOTheory Astronomical Objects

This is the description of the namespace http://docs.g-vo.org/rdf/theory/AstronomicalObjects as of 2019-02-27.

This vocabulary is not yet approved by the IVOA. This means that terms can still disappear without prior notice.

Concepts in this vocabulary are intended to be used to describe simulated astronomical objects in SimDM classes. This is a SKOS version of the OWL ontology proposed in the IVOA Note “Ontology of Astronomical Object Types” (http://www.ivoa.net/documents/Notes/AstrObjectOntology/).
