The Getty Thesaurus of Geographic Names (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 (Geographical Information System), maps, and other geographic resources.
This controlled vocabulary may be used by someone cataloguing or indexing a collection as it provides preferred names or terms. It may also be helpful in retrieval of information from documentation systems and research into collections as it shows links and paths between subject matter. The TGN grows and changes via contributions from the user community and editorial work of the Getty Vocabulary Program.
