The ISO 25964 data model for the structure of an information retrieval thesaurus

Abstract

International standard ISO 25964-1: 2011 - Thesauri for information retrieval, includes a detailed data model for thesaurus structure. It is intended to provide a rigorous presentation of the elements and relationships which will not only clarify and standardise the varying and conflicting interpretations which exist but which can also be implemented consistently in automated systems. It makes a clear distinction between concepts and the terms which are used to label them, and includes other features that may be present in a thesaurus, such as compound equivalence, arrays and node labels, concept groups, notes and version history.
