The document discusses the Getty Vocabularies, which are authoritative controlled vocabularies for art, architecture, and material culture. They include the Art & Architecture Thesaurus (AAT), Getty Thesaurus of Geographic Names (TGN), Union List of Artist Names (ULAN), and the developing Cultural Objects Name Authority (CONA). The vocabularies are compiled and maintained by the Getty Vocabulary Program based on contributions from users and projects. Records are merged if multiple contributors submit the same concept, person, place, or object. The vocabularies are licensed and distributed annually to institutions.
