It is the [[international standard]] ([[International Organization for Standardization|ISO]] 21127:2006)<ref>[http://www.iso.org/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=34424&scopelist=PROGRAMME ISO 21127:2006 (Information and documentation — A reference ontology for the interchange of cultural heritage information)]</ref> for controlled exchange of cultural heritage information. [[Archive]]s, [[library|libraries]], [[Museum|museums]], and other cultural institutions are encouraged to use the CIDOC CRM to enhance accessibility of [[knowledge]].
The aim of the CIDOC CRM is to provide aan information standard against whichthat museums, and other cultural heritage institutions, can use to describe their collections and related entities in ways that enable this information to be better shared between information systems. It does this by providing a high-level conceptual reference model of their [[Formal semantics of programming languages|formal semantics]].Thuswhereby everyeach single pieceunit of information can be assigned to the concepts of the CIDOC CRM. At the same time this process creates important pre-conditions for themachine-to-machine [[information integration]], because the CIDOC CRM can be used as a source for the development of tools for scheme transformation and scheme integration as well. The CIDOC CRM supports the formulation of needs for [[information system]]s and can serve as guideline and help for semantic, [[Data modeling|data]], or [[Database model|database]] modeling.
CIDOC CRM lends itself to be implemented using [[Extensible Markup Language|XML]] and [[Resource Description Framework|RDF]].
