Web Ontology Language & Erlangen CRM

The CIDOC CRM itself must, however, be implemented as a formal ontology that can be interpreted by computers for use in the Semantic Web in general and in WissKI in particular. WissKI itself uses Erlangen CRM, an implementation of CIDOC CRM in OWL DL, a dialect of the Web Ontology Language (OWL). Erlangen CRM implements all classes and relations of CIDOC CRM and tries to stay as close as possible to the model. The Erlangen CRM is the only implementation of the CIDOC CRM in OWL DL that has been maintained for several years and is recognized by the CIDOC SIG as an official implementation.
The Web Ontology Language was developed for the Semantic Web. It is based on the Resource Description Framework (RDF), which provides data in the form of statements according to the
Schema subject - predicate - object represented in the form of triples. The central components of OWL are concepts, relations and individuals. The relations are directed and possible between two concepts. To store data, the concepts are instantiated in the form of individuals.
