• On the Getty Web site: Users may search for individual terms and names in the Getty Vocabularies online. The online data is refreshed monthly. 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).


• Additional formats: The AAT, ULAN, and TGN are available in releases of XML and relational tables, refreshed periodically throughout the year. AAT, TGN, ULAN, CONA, and IA are also available via Web Services. Data is no longer available in a MARC format release, although we possibly may develop and make available a transformation script for an existing release format to MARC.
  
  See links to the full data sets, data dictionaries, and more information at the Download Center.

NOTE: LOD will likely be the most sustainable format over time. Developers who use one of the other release formats are advised to consider transitioning to LOD.

  On other sites: The Getty Vocabularies may be found in various implementations outside of the Getty. Among implementations available to the public are the following: The AAT is included in translations available at sites maintained in Chile, Germany, and Taiwan; the ULAN is incorporated in the VIAF (Virtual International Authority File) data sets, and TGN will be incorporated in VIAF in future.

• Data Dictionaries: The data dictionaries and other documentation describe the release formats and content of the Getty Vocabularies. They do not give step-by-step instructions on how to construct a database or interface based on the data files; analysis and programming resources will be required to implement the Vocabularies. The Getty does not provide technical support. View the data dictionaries and data from our Download Center.
