The Getty Thesaurus of Geographic Names (abbreviated TGN) is a product of the J. Paul Getty Trust included in the Getty Vocabulary Program. The TGN includes names and associated information about places. Places in TGN include administrative political entities (e.g., cities, nations) and physical features (e.g., mountains, rivers). Current and historical places are included. Other information related to history, population, culture, art and architecture is included.
The resource is available to museums, art libraries, archives, visual resource collection catalogers, bibliographic projects through private license or available to members of the general public for free on the Getty Vocabulary website (see external links).
The Getty vocabulary databases (Art & Architecture Thesaurus (AAT), Union List of Artist Names (ULAN), and TGN) are produced and maintained by the Getty Vocabulary Program. They are compliant with ISO and NISO standards for thesaurus construction. They contain terms, names, and other information about people, places, things, and concepts relating to art, architecture, and material culture.
The Getty vocabularies can be used in three ways: at the data entry stage, by catalogers or indexers who are describing works of art, architecture, material culture, archival materials, visual surrogates, or bibliographic materials; as knowledge bases, providing information for researchers; and as search assistants to enhance end-user access to online resources.[1]
History
Work on the TGN began in 1987, when the Getty created a department dedicated to compiling and distributing terminology, at that time called the Vocabulary Coordination Group. The AAT was already being managed by the Getty at that time, and the Getty attempted to respond to requests from the creators of art information for additional controlled vocabularies for artists' names (ULAN) and geographic names (TGN). The development of TGN was informed by an international study completed by the Thesaurus Artis Universalis (TAU), a working group of the Comité International d'Histoire de l'Art (CIHA), and by the consensus reached at a colloquium held in 1991, attended by the spectrum of potential users of geographic vocabulary in cataloging and scholarship of art and architectural history and archaeology. The initial core of the TGN was compiled from thousands of geographic names in use by various Getty cataloging and indexing projects, enlarged by information from U. S. government databases, and further enhanced by the manual entry of information from published hard-copy sources. The TGN grows and changes via contributions from the user community and editorial work of the Getty Vocabulary Program.
The basic principles under which the TGN is constructed and maintained were established by the Art & Architecture Thesaurus (AAT) and also employed for the Union List of Artist Names (ULAN): Its scope includes terminology needed to catalog and retrieve information about the visual arts and architecture; it is constructed using national and international standards for thesaurus construction; it comprises a hierarchy with tree structures corresponding to the current and historical worlds; it is based on terminology that is current, warranted for use by authoritative literary sources, and validated by use in the scholarly art and architectural history community; and it is compiled and edited in response to the needs of the user community.
TGN was founded under the management of Eleanor Fink (head of what was then called the Vocabulary Coordination Group, and subsequently Director of the Art History Information Program, later called the Getty Information Institute). TGN has been constructed over the years by numerous members of the user community and an army of dedicated editors, under the supervision of several managers. Technical support for the TGN was provided by the Getty. TGN was first published in 1997 in machine-readable files. Given the growing size and frequency of changes and additions to the TGN, hard-copy publication was deemed to be impractical. It is currently published in both a searchable online Web interface and in data files available for licensing. The data for the TGN is compiled and edited in an editorial system that was custom-built by Getty technical staff to meet the unique requirements of compiling data from many contributors, building complex and changing polyhierarchies, merging, moving, and publishing in various formats. Final editorial control of the TGN is maintained by the Getty Vocabulary Program, using well-established editorial rules. The current managers of the TGN are Patricia Harpring, Managing Editor, and Murtha Baca, Head, Vocabulary Program and Digital Resource Management.[2]
TGN is a structured vocabulary currently containing around 1,106,000 names and other information about places. Names for a place may include names in the vernacular language, English, other languages, historical names, names and in natural order and inverted order. Among these names, one is flagged as the preferred name.
TGN is a thesaurus, compliant with ISO and NISO standards for thesaurus construction; it contains hierarchical, equivalence, and associative relationships. Note that TGN is not a GIS (Geographic Information System). While many records in TGN include coordinates, these coordinates are approximate and are intended for reference only.
The focus of each TGN record is a place. There are around 912,000 places in the TGN. In the database, each place record (also called a subject) is identified by a unique numeric ID. Linked to the record for the place are names, the place's parent or position in the hierarchy, other relationships, geographic coordinates, notes, sources for the data, and place types, which are terms describing the role of the place (e.g., inhabited place and state capital). The temporal coverage of the TGN ranges from prehistory to the present and the scope is global.
Design
The TGN is a faceted classification system as well as a poly-hierarchical one. There are two facets: World and Extraterrestrial. Within the World facet are Physical Features and Political Entities. One can view administrative places from as broad as continents and regions to as specific as neighborhoods, boroughs, towns, and cities. Within the Physical Features facets are mountain ranges, oceans, seas, rivers, waterfalls, island groups, and deserts.
The record for each concept includes its place in the hierarchy (with a link to its parent), as well as links to related terms, related concepts, sources for the data, and notes.

Getty Vocabulary Editorial Guidelines The editorial guidelines for the AAT, ULAN, and TGN contain rules and guidelines intended for use by the editors of the Getty Vocabulary Program using the in-house editorial system, VCS (Vocabulary Coordination System). Contributors to the Getty Vocabularies and implementers of the licensed vocabulary data may consult these guidelines as well.
Training materials and presentations created by the Getty Vocabulary Program The documents on this page include presentations and other training materials for the Getty Thesaurus of Geographic Names (TGN), the Union List of Artist Names (ULAN), the Art & Architecture Thesaurus (AAT), Cataloging Cultural Objects (CCO), Categories for the Description of Works of Art (CDWA), and standards in general.

A faceted classification is a classification scheme used in organizing knowledge into a systematic order. A faceted classification uses semantic categories, either general or subject-specific, that are combined to create the full classification entry. Many library classification systems use a combination of a fixed, enumerative taxonomy of concepts with subordinate facets that further refine the topic.
Controlled vocabularies provide a way to organize knowledge for subsequent retrieval. They are used in subject indexing schemes, subject headings, thesauri, taxonomies and other knowledge organization systems. Controlled vocabulary schemes mandate the use of predefined, preferred terms that have been preselected by the designers of the schemes, in contrast to natural language vocabularies, which have no such restriction.
The Library of Congress Subject Headings (LCSH) comprise a thesaurus of subject headings, maintained by the United States Library of Congress, for use in bibliographic records. LC Subject Headings are an integral part of bibliographic control, which is the function by which libraries collect, organize, and disseminate documents. It was first published in 1898, a year after the publication of Library of Congress Classification (1897). The last print edition was published in 2016. Access to the continuously revised vocabulary is now available via subscription and free services.
A finding aid, in the context of archival science, is an organization tool, a document containing detailed, indexed, and processed metadata and other information about a specific collection of records within an archive. Finding aids often consist of a documentary inventory and description of the materials, their source, and their structure. The finding aid for a fonds is usually compiled by the collection's entity of origin, provenance, or by an archivist during archival processing, and may be considered the archival science equivalent of a library catalog or a museum collection catalog. The finding aid serves the purpose of locating specific information within the collection. The finding aid can also help the archival repository manage their materials and resources. The history of finding aids mirrors the history of information. Ancient Sumerians had their own systems of indexes to locate bureaucratic and administrative records. Finding aids in the 19th and 20th centuries were paper documents, such as lists or index cards. In the 21st century, they can be created in electronic formats like spreadsheets or databases. The standard machine-readable format for manuscript collection finding aids, widely used in the United States, Canada, the United Kingdom, France, Australia and elsewhere, is Encoded Archival Description.
Simple Knowledge Organization System (SKOS) is a W3C recommendation designed for representation of thesauri, classification schemes, taxonomies, subject-heading systems, or any other type of structured controlled vocabulary. SKOS is part of the Semantic Web family of standards built upon RDF and RDFS, and its main objective is to enable easy publication and use of such vocabularies as linked data.
The Getty Research Institute (GRI), located at the Getty Center in Los Angeles, California, is "dedicated to furthering knowledge and advancing understanding of the visual arts".
DOCAM was an international alliance of researchers from various institutions and disciplines dedicated to the documentation and conservation of media arts. The project was the result of a five-year mandate lasting from 2005 until 2010. Outcomes of the project include a cataloguing guide incorporating case studies, a conservation guide explaining preservation issues specific to time-based media, a technological timeline, a documentation model for digital curation and preservation of time-based media, and a glossary and thesaurus for media arts.
The Art & Architecture Thesaurus (AAT) is a controlled vocabulary used for describing items of art, architecture, and material culture. The AAT contains generic terms, such as "cathedral," but no proper names, such as "Cathedral of Notre Dame." The AAT is used by, among others, museums, art libraries, archives, catalogers, and researchers in art and art history. The AAT is a thesaurus in compliance with ISO and NISO standards including ISO 2788, ISO 25964 and ANSI/NISO Z39.19.
Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including:
The Getty Vocabulary Program is a department within the Getty Research Institute at the Getty Center in Los Angeles, California. It produces and maintains the Getty controlled vocabulary databases, Art and Architecture Thesaurus, Union List of Artist Names, and Getty Thesaurus of Geographic Names. They are compliant with ISO and NISO standards for thesaurus construction. The Getty vocabularies are the premiere references for categorizing works of art, architecture, material culture, and the names of artists, architects, and geographic names. They have been the life work of many people and continue to be critical contributions to cultural heritage information management and documentation. They contain terms, names, and other information about people, places, things, and concepts relating to art, architecture, and material culture. They can be accessed online free of charge on the Getty website.
Categories for the Description of Works of Art (CDWA) describes the content of art databases by articulating a conceptual framework for describing and accessing information about works of art, architecture, other material culture, groups and collections of works, and related images. The CDWA includes 532 categories and subcategories. A small subset of categories are considered core in that they represent the minimum information necessary to identify and describe a work. The CDWA includes discussions, basic guidelines for cataloging, and examples.
The Schlagwortnormdatei or SWD is a controlled vocabulary index term system used primarily for subject indexing in library catalogs. The SWD is managed by the German National Library (DNB) in cooperation with various library networks. The inclusion of keywords in the SWD is defined by Regeln für die Schlagwortkatalogisierung (RSWK). Similar authority systems in other languages include the Library of Congress Subject Headings (LCSH) and the Répertoire d’autorité-matière encyclopédique et alphabétique unifié (RAMEAU). Since April 2012 the SWD is part of the Gemeinsame Normdatei (GND).
ISO 25964 is the international standard for thesauri, published in two parts as follows:
ISO 25964 Information and documentation - Thesauri and interoperability with other vocabulariesPart 1: Thesauri for information retrieval [published August 2011] Part 2: Interoperability with other vocabularies [published March 2013]
The Cultural Objects Name Authority (CONA) is a project by the Getty Research Institute to create a controlled vocabulary containing authority records for cultural works, including architecture and movable works such as paintings, sculpture, prints, drawings, manuscripts, photographs, textiles, ceramics, furniture, other visual media such as frescoes and architectural sculpture, performance art, archaeological artifacts, and various functional objects that are from the realm of material culture and of the type collected by museums. The focus of CONA is works cataloged in scholarly literature, museum collections, visual resources collections, archives, libraries, and indexing projects with a primary emphasis on art, architecture, or archaeology. The target users are the visual resources, academic, and museum communities.
In the context of information retrieval, a thesaurus is a form of controlled vocabulary that seeks to dictate semantic manifestations of metadata in the indexing of content objects. A thesaurus serves to minimise semantic ambiguity by ensuring uniformity and consistency in the storage and retrieval of the manifestations of content objects. ANSI/NISO Z39.19-2005 defines a content object as "any item that is to be described for inclusion in an information retrieval system, website, or other source of information". The thesaurus aids the assignment of preferred terms to convey semantic metadata associated with the content object.
The documentation of cultural property is a critical aspect of collections care. As stewards of cultural property, museums collect and preserve not only objects but the research and documentation connected to those objects, in order to more effectively care for them. Documenting cultural heritage is a collaborative effort. Essentially, registrars, collection managers, conservators, and curators all contribute to the task of recording and preserving information regarding collections. There are two main types of documentation museums are responsible for: records generated in the registration process—accessions, loans, inventories, etc. and information regarding research on objects and their historical significance. Properly maintaining both types of documentation is vital to preserving cultural heritage.
A Collections Management System (CMS), sometimes called a Collections Information System, is software used by the collections staff of a collecting institution or by individual private collectors and collecting hobbyists or enthusiasts. Collecting institutions are primarily museums and archives and cover a very broad range from huge, international institutions, to very small or niche-specialty institutions such as local historical museums and preservation societies. Secondarily, libraries and galleries are also collecting institutions. Collections Management Systems (CMSs) allow individuals or collecting institutions to organize, control, and manage their collections' objects by “tracking all information related to and about” those objects. In larger institutions, the CMS may be used by collections staff such as registrars, collections managers, and curators to record information such as object locations, provenance, curatorial information, conservation reports, professional appraisals, and exhibition histories. All of this recorded information is then also accessed and used by other institutional departments such as “education, membership, accounting, and administration."
The Répertoire de vedettes-matière de l'Université Laval (RVM) is a controlled vocabulary made up of four mostly bilingual thesauruses. It is designed for document indexers, organizations that want to describe the content of their documents or of their products and services, as well as anyone who wants to clarify vocabulary in English and French as part of their work or research.
