Web Ontology Language is an ontology description language for the Semantic Web. The OWL language allows the description of classes and the relationships between them common to web documents and applications.
OWL is based on the earlier OIL and DAML+OIL languages and is currently the recommended language of the World Wide Web Consortium.
Digital platforms: Cross-platform software
The language is based on a representation of reality in an object-property data model. OWL is not only suitable for describing web pages, but also any reality objects. Each element of the description in this language (including the properties linking the objects) is associated with a URI.
