The Getty vocabulary data can be obtained in several ways:

  • On the Getty Web site, free of charge, for searching individual terms and names. The data is refreshed every two weeks. The Getty vocabularies are made available via the Web to support limited research and cataloging efforts only. Licensing is required for more extensive use of these tools.

  • By licensing the raw data files. The AAT, ULAN, and TGN are currently available in XML and relational tables, which are released in July annually. This data includes no software. Customized versions of these files are not available. The data is also available via Web Services, for which data is refreshed every two weeks; this data is "in process," meaning it may change with the annual release in July of each year. Please go to the Download Center for more information about licensing, Web Services, and sample data.

  • Linked Open Data: The project to publish all four of the Getty vocabularies as Linked Open Data (LOD) is underway. It is anticipated that the data will be published under the ODC_BY 1.0 license. However, we anticipate that releases in XML and Relational Tables will also continue for some time, and that licenses will remain in place for these release formats. For target release dates and news on the LOD project, click Vocabularies as LOD in the left navigation.

  • As part of a collection management system or other information system from one of the following vendors: Adlib Information Systems, Cuadra Associates, Gallery Systems, KE Software/KE EMu, Luna Imaging, Questor Systems, Vernon Systems, or Willoughby Associates.


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 in local systems. The Getty does not provide technical support for its licensed vocabulary data.
