The Getty Vocabularies are made available via this Web interface to support research and cataloging efforts. See below how URIs may be used to refer to the vocabulary records if incorporated in your data.


• Through online tools: The AAT, ULAN, and TGN are available through an OpenRefine reconciliation service and via a SPARQL end point. To learn about interesting questions you can ask of the Vocabularies using SPARQL, see over 90 sample queries in Sample Queries: Finding Subjects.


• LOD formats: Users may acquire the full data for AAT, TGN, and ULAN in N-Triples format, refreshed periodically throughout the year. Also, individual records may be downloaded in JSON, RDF, N3/Turtle, and N-Triples formats. See Linked Open Data (LOD).


• Archived Data and Services: Getty no longer releases the Vocabularies in XML and 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 was 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.
