data value standard

n. a set of options that govern the content of a metadata element


Data value standard is not a synonym for controlled vocabulary. Controlled vocabularies and thesauri are data value standards when used by archivists in structured metadata contexts. However, controlled vocabularies and thesauri can be put to other uses, and data value standards may take other forms, such as classification schemes. Examples of data value standards include the Library of Congress Name Authority File, the Library of Congress Subject Cataloging Manual, the Art and Architecture Thesaurus, and ICONCLASS.
