The following information and examples may guide those who wish to use the data releases of AAT, ULAN, or TGN. For catalogers, researchers, and other users who wish to search for individual records in AAT, ULAN, TGN, CONA, or IA, see the search interface linked from the Getty Vocabularies online, refreshed monthly. Users may also access AAT, ULAN, and TGN through an OpenRefine reconciliation service.

The Getty Vocabularies change and grow over time; thousands of records are edited or added each year. Implementers are encouraged to refresh the data regularly. The Getty Vocabulary data is made available by the J. Paul Getty Trust under the Open Data Commons Attribution License (ODC-By) 1.0. Note that the Getty Vocabulary data is compiled from various contributors using published sources; the contributor and sources should be cited along with the name of the Vocabulary and the J. Paul Getty Trust when the data is displayed.

Archived Data and Services
Getty no longer releases the Vocabularies in XML or relational table formats. To access final datasets in these formats (drawn on January 30, 2026), see AAT downloads, TGN downloads, and ULAN downloads. Each archived dataset carries its own documentation. Archived data will not be refreshed, although later updates may be added in the future. Additionally, XML web services for AAT, TGN, and ULAN, which previously provided data that were regularly refreshed, have been discontinued. Users are encouraged to adapt their data pipelines to Linked Open Data (LOD) formats in preparation for this change and may contact Mark Pyzyk at MPyzyk@getty.edu for consultation on the transition. CONA/IA web services data was last updated on January 30, 2026.

AAT: AAT is a hierarchical vocabulary; the full published data set contains around 74,870 records (subject_id, as of January 2026) for generic concepts (not having proper names). Included are terms, scope notes, bibliographic citations, and other information relating to fine art, architecture, decorative arts, archival materials, archaeology, conservation, and other material culture. AAT is not comprehensive, but grows through contributions; its scope includes terminology necessary for cataloging, linking, and discovery of information about the visual arts.

ULAN:. ULAN is a structured vocabulary; the full published data set contains around 527,150 records (subject_id, as of January 2026), including names, and biographical and bibliographic information for artists, architects, sitters, patrons firms, studios, and art repositories. ULAN is not comprehensive, but includes records as necessary for cataloging, linking, and discovery of information about visual arts. Included are a wealth of variant names, pseudonyms, and language variants.

TGN: . TGN is a unique hierarchical vocabulary intended for cataloging, linking, and discovery of visual arts information; the full published data set contains around 3,020,170 records (subject_id, as of January 2026), including names, place types, coordinates, and descriptive notes. TGN is not comprehensive; it focuses on current and historical places and sites important for the study of art, architecture, conservation, and related disciplines. TGN is not a GIS; coordinates are included for many records, but they are for finding purposes only (i.e., to find the place on a map).
