Describes general techniques for document analysis which should apply in all indexing situations. These techniques can be employed by any agency in which human indexers analyse the subjects of documents and express these subjects in indexing terms. Is intended to promote standard practice within an agency or network of agencies as well as between different indexing agencies, especially those which exchange bibliographic records.

The recommendations are intended to ensure consistent practice within a single indexing agency, or between different agencies (for example members of a network). These recommendations relate to monolingual thesauri, without reference to the special requirements of multilingual thesauri.

SO 25964-1:2011 gives recommendations for the development and maintenance of thesauri intended for information retrieval applications.

ISO 25964-1:2011 is not applicable to the databases or software used directly in search or indexing applications, but does anticipate the needs of such applications among its recommendations for thesaurus management.

ISO 25964-2:2013 is applicable to thesauri and other types of vocabulary that are commonly used for information retrieval. It describes, compares and contrasts the elements and features of these vocabularies that are implicated when interoperability is needed. It gives recommendations for the establishment and maintenance of mappings between multiple thesauri, or between thesauri and other types of vocabularies.

Standardization in the field of terminology, technologies, materials and equipment for monitoring, evaluation,preservation and restoration of cultural heritage.
