CIDOC CRM in OWL 2 provides an encoding of the CIDOC Conceptual Reference Model (CRM) as an OWL 2 DL ontology. CIDOC CRM in OWL 2 is an alternative to the existing RDFS and OWL DL versions, making use of new OWL 2 constructs for a more accurate representation of the model, and uses stable, host- and version-independent URIs.
The CIDOC Conceptual Reference Model (CRM) itself provides definitions and a formal structure for describing the implicit and explicit concepts and relationships used in cultural heritage documentation.
The CIDOC CRM is intended to promote a shared understanding of cultural heritage information by providing a common and extensible semantic framework that any cultural heritage information can be mapped to. It is intended to be a common language for domain experts and implementers to formulate requirements for information systems and to serve as a guide for good practice of conceptual modelling. In this way, it can provide the "semantic glue" needed to mediate between different sources of cultural heritage information, such as that published by museums, libraries and archives.
