In library, information and documentation science (BID), an authority file is a directory of standardized terms for use as a descriptor in documentation . A standard file is thus a form of a controlled vocabulary , in which it is determined which entry in the opening is to be used. In English, authority files are referred to as authority files .
Standardized terms can be personal names , corporate names and any other set of names for things, processes or abstract terms. The formation of standard terms is based on an ontology that defines the terms to be standardized and the type of standardization. After allocation, the standard terms belong to the metadata of the respective data set.
The free allocation of categories, keywords or tags can be considered a preliminary form, but this adheres to certain rules, such as the definition of singular or plural , the preferred use of compound words , etc.
In the German-speaking area, efforts to establish joint authority data began in 1973 with the joint corporation file (GKD) by the Bavarian State Library , the State Library of Prussian Cultural Heritage and the German Library .
Well-known library authority files are the Common Authority File (GND), which is cooperatively managed by the German National Library (DNB), all German-speaking library associations , the journal database (ZDB) and numerous other institutions, the Library of Congress Name Authorities Files (LCNAF) and the Système universitaire de documentation (SUDOC) of the French union catalog.
A number of authority files exist in the field of museums. These are often subject-specific and are operated internationally, e.g. B. nomisma.org for numismatics or the Union List of Artist Names (ULAN) from the Getty Research Institute and the RKD-ID for artists. These authority data are freely available and are used by Wikidata , among others . These normative data are interesting because they have APIs, represent specialist knowledge and are provided with descriptions, picture credits and references to other normative data.
