The Getty ULAN (Union List of Artist Names) is a structured vocabulary that includes names and associated information about artists. Artists may be either be individuals or groups of individuals working together (corporate bodies). Artists in the ULAN generally represent creators involved in the conception or production of visual arts and architecture. When associated with a project field, the ULAN can be used as a controlled vocabulary or data value standard. Shared Shelf Names builds from the Getty ULAN.
The Getty AAT (Art and Architecture Thesaurus) is a structured vocabulary containing terms and other information about concepts. When associated with a project field, the AAT can be used as a controlled vocabulary or data value standard.
Terms in the AAT may be used to describe art, architecture, decorative arts, material culture, and archival materials. The AAT contains generic terms; it contains no iconographic subjects and no proper names. That is, each concept is a case of many (a generic thing), not a case of one (a specific thing). For example, the generic term cathedral is in the AAT, but the specific proper name Chartres Cathedral is out of scope for the AAT.
The Getty TGN (Thesaurus of Geographic Names) is a structured vocabulary that can be used to improve access to information about art, architecture, and material culture. The TGN includes names and associated information about places. Places in the TGN include administrative political entities (e.g., cities, nations) and physical features (e.g., mountains, rivers). Current and historical places are included. Names for a place may include names in the vernacular language, English, other languages, historical names, names in natural order and inverted order. Among these names, one is flagged as the preferred name. The TGN is a thesaurus, compliant with ISO and NISO standards for thesaurus construction; it contains hierarchical, equivalence, and associative relationships. Note that the TGN is not a GIS (Geographic Information System). While many records in TGN include coordinates, these coordinates are approximate and are intended for reference only.
