ISO 21127 - Das CIDOC Conceptual Reference Model

The CIDOC Conceptual Reference Model (CIDOC CRM) has been developed for more than a decade by experts from museums, archives and libraries in collaboration with philosophers and computer scientists as part of a Working Group on Documentation (CIDOC SIG) of the International Council of Museums (ICOM). It is a formal model that seeks to map and make interchangeable the heterogeneous information of humanities and cultural studies across disciplines. The current version 6.2 defines 89 concepts and 149 relations, each explained by a short documentation (Scope Note) and illustrated by examples. Two key points distinguish CIDOC CRM from other ontologies: On the one hand, the documentation is event-centered. This means that every step in the history of a subject, be it a physical or conceptual object or a person, is described by events (such as a person's birth and death) and not by states (being alive). The events connect the documented subjects with other objects, acting persons, time and place and further information. On the other hand, CIDOC CRM separates things and their names. Thus, the identity of a person is not determined by his name, whereby facts can be modeled, such as: The identity of two persons is different, but the name is identical.
