Art & Architecture Thesaurus

Art & Architecture Thesaurus

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 and ISO 5964.

History

The AAT project began in the late 1970s in response to the gradual automation of records by art libraries, art journal indexing services, and catalogers of museum objects and visual resources. Automation required consistency in cataloging as well as more efficient retrieval of information; a controlled vocabulary was a solution to both these problems. The project was conceived by library directors and architectural experts Toni Petersen, Dora Crouch, and Pat Molholt and was originally headquartered in Williamstown, Massachusetts, with the J. Paul Getty Trust providing technical advice and funding. In 1983 the Getty Trust took over editorial responsibility and the AAT offices relocated to the Getty's Los Angeles headquarters in order to better coordinate with two other similar Getty projects, the Union List of Artist Names (ULAN) and Getty Thesaurus of Geographic Names (TGN).

The AAT was published in 1990 and 1994 in both print and electronic form. By 1997, the size and frequency of updates made hard-copy publication unfeasible and the decision was made to publish via a searchable online Web interface and in data files available for licensing. Final editorial control of the AAT is maintained by the Getty Vocabulary Program.

Terms

The initial core set of terms was derived from authority lists and the literature of art and architectural history; this core set was reviewed, approved and added to by an advisory team made up scholars from all relevant disciplines, including art and architectural historians, architects, librarians, visual resource curators, archivists, museum personnel, and specialists in thesaurus construction. Its hierarchy was inspired by the Medical Subject Headings. All eras from antiquity to the present are covered, and it is not limited geographically.

As of January 2007, the AAT contained approximately 131,000 terms. While the thesaurus contains many variations on a term, such as singular and plural forms, spelling variants, various forms of speech, and synonyms, one is always flagged as the preferred term. Terms are updated monthly and regular users are encouraged to propose new terms.

Design

The AAT is a faceted classification system as well as a hierarchical one. There are seven facets:

* Associated Concepts - abstract concepts, such as beauty, balance, connoisseurship, metaphor, freedom, socialism (Hierarchy: Associated concepts)
* Physical Attributes - perceptible or measurable characteristics such as size, shape, chemical properties, texture and hardness, such as strapwork, borders, round, waterlogged, brittleness. (Hierarchies: Attributes and Properties, Conditions and Effects, Design Elements, Color)
*Styles and Periods - stylistic groupings and distinct chronological periods, such as French, Louis XIV, T'ang Dynasty, Chippendale (Hierarchy: Styles and Periods)
* Agents - people, groups of people, and organizations such as printmakers, landscape architects, corporations, religious orders. (Hierarchies: People, Organizations)
* Activities - areas of endeavor, physical and mental actions or methods, such as archaeology, engineering, analyzing, contests, exhibitions, running, drawing (image-making), corrosion. (Hierarchies: Disciplines, Functions, Events, Physical and Mental Activities, Processes and Techniques)
* Materials - physical substances, such as iron, clay, adhesive, emulsifier, artificial ivory, millwork, nylon. (Hierarchy: Materials)
* Objects - objects either fabricated or given form by human activity, such as paintings, amphorae, facades, cathedrals, Brewster Chairs, gardens (Hierarchies: Object Groupings and Systems, Object Genres, Components; Built Environment: Settlements and Landscapes, Built Complexes and Districts, Single Built Works, Open Spaces and Site Elements; Furnishings and Equipment: Furnishings, Costume, Tools and Equipment, Weapons and Ammunition, Measuring Devices, Containers, Sound Devices, Recreational Artifacts, Transportation Vehicles; Visual and Verbal Communication: Visual Works, Exchange Media, Information Forms)

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.
