Getty Thesaurus of Geographic Names is an international structured vocabulary and authority file for geographic names developed and maintained by the J. Paul Getty Trust. It supports cataloging, research, and digital humanities projects by linking to records associated with places such as Rome, Beijing, Cairo, New York City and Lima, providing standardized identifiers used by institutions like the Library of Congress, British Library, Smithsonian Institution, Bibliothèque nationale de France and the National Gallery of Art. The Thesaurus interoperates with datasets and projects including Wikidata, Europeana, WorldCat, Getty Provenance Index and Digital Public Library of America to facilitate discovery across collections.

Overview

The Thesaurus is an extensive controlled vocabulary of place names that records preferred names, alternative names, coordinates, hierarchies and historical information for places such as Alexandria, Constantinople, Istanbul, Jerusalem and Mecca, and links to related cultural heritage entities like Acropolis of Athens, Palace of Versailles, Great Wall of China, Machu Picchu, and Angkor Wat. It serves museums, archives, libraries and research centers including the Metropolitan Museum of Art, Getty Museum, Victoria and Albert Museum, National Archives (United Kingdom), and The British Museum by enabling consistent metadata for objects, manuscripts, maps and photographs associated with regions such as Tuscany, Andalusia, Bavaria, Siberia and Mesopotamia.

The project originated within the J. Paul Getty Trust's initiatives in the late 20th century and evolved in dialogue with institutions like the International Council on Archives, International Federation of Library Associations and Institutions, Museum Computer Network, OCLC and the Getty Research Institute. Early milestones intersected with standards and projects such as the development of CIDOC Conceptual Reference Model, the adoption of ISO 3166, coordination with Library of Congress Subject Headings, and collaborations with the National Endowment for the Humanities and Andrew W. Mellon Foundation. Major expansions occurred alongside digitization programs connected to the Google Books project, Europeana Collections, and the rise of linked data initiatives championed by Tim Berners-Lee, Sir Tim Berners-Lee-related communities and W3C working groups.

Records in the Thesaurus include granular data fields for names, scope notes, hierarchical broader/narrower relations, and geographic coordinates applicable to places such as Tenochtitlan, Cuzco, Petra, Pompeii and Babylon. The vocabulary models temporal and spatial facets that reflect historical changes associated with entities like Ottoman Empire, Austro-Hungarian Empire, British Empire, Roman Empire and Ming dynasty. It cross-references cultural and built heritage landmarks such as Hagia Sophia, Notre-Dame de Paris, Forbidden City, Alhambra, and Statue of Liberty, and aligns with authorities including Getty Union List of Artist Names, Library of Congress Name Authority File, and International Standard Name Identifier.

The Thesaurus is accessible via web interfaces and APIs used by platforms like OCLC WorldShare, Amazon Web Services-hosted repositories, and content management systems employed by Harvard University, Yale University, Princeton University, University of Oxford, and Stanford University. Its linked data publication practices permit integration with Wikimedia Commons, Wikidata, Europeana, Digital Public Library of America and research portals such as Perseus Digital Library and Pelagios. Institutions integrate the Thesaurus into systems including TMS (The Museum System), CollectionSpace, ArchivesSpace and Blacklight-based discovery layers to normalize place terms for collections originating in regions like Mesopotamia, Phoenicia, Anatolia, Andes and Levant.

Scholars in fields working with primary sources and cultural artifacts employ the Thesaurus to disambiguate locations in projects concerning Napoleon, Cleopatra, Genghis Khan, Christopher Columbus and Marco Polo, to support georeferencing of historical maps from the British Library and Bibliothèque nationale de France, and to enrich catalog records at institutions such as the Museum of Modern Art, Tate Modern, National Portrait Gallery, Rijksmuseum, and Prado Museum. Digital humanities initiatives like the Pelagios Network, Mapping Gothic, Old Weather, Linked Open Data for Libraries (LODLAM), and large-scale aggregation efforts such as Europeana Collections and Digital Public Library of America leverage the Thesaurus for place reconciliation, GIS mapping, and semantic enrichment of datasets from areas including Galicia, Brittany, Catalonia, Saxony and Piedmont.

Governance is undertaken by the Getty Research Institute and the Getty Vocabulary Program in coordination with partner organizations such as the International Council of Museums, OCLC Research, Library of Congress, and advisory input from scholars at institutions like University of California, Berkeley, University of Cambridge, Columbia University, University of Chicago, and Princeton University. Maintenance workflows follow editorial policies analogous to standards from ISO, Dublin Core Metadata Initiative, and the CIDOC CRM community, and involve contributions, editorial review, and change logs used by aggregators including WorldCat, Europeana, and Wikidata to keep records current for sites like Pompeii, Auschwitz-Birkenau, Stonehenge, Chichen Itza, and Serengeti.
