According to the Getty Vocabularies website, "The Getty vocabularies contain structured terminology for art, architecture, decorative arts, archival materials, visual surrogates, conservation, and bibliographic materials. Compliant with international standards, they provide authoritative information for catalogers, researchers, and data providers. The vocabularies grow through contributions."
Currently there are four components:
The Union List of Artist Names (ULAN)– structured vocabulary, including names, biographies, related people, and other metadata about artists, architects, firms, studios, museums, patrons, sitters, and other people and groups involved in the creation and study of art and architecture.
The Art & Architecture Thesaurus (AAT)– structured vocabulary, including terms, descriptions, and other metadata for generic concepts related to art, architecture, conservation, archaeology, and other cultural heritage. Included are work types, styles, materials, techniques, and others.
The Getty Thesaurus of Geographic Names (TGN)– TGN is a structured vocabulary, including names, descriptions, and other metadata for extant and historical cities, empires, archaeological sites, and physical features important to research of art and architecture. TGN may be linked to GIS, maps, and other geographic resources.
The Cultural Objects Name Authority (CONA)– titles, attributions, depicted subjects, and other metadata about works of art, architecture, and other cultural heritage, both extant and historical, physical and conceptual, linked to museum collections, special collections, archives, libraries, scholarly research, and other resources.
At the moment, the CultureTech Licensing Management Tool maps certain data fields to the ULAN database only, but in the future, more fields may be mapped to more databases, and the ability to submit contributions directly to the Getty Vocabularies may be possible.
