Web Ontology Language (OWL)

Glossary Page

The W3C Web Ontology Language (OWL) is a Semantic Web platform created to represent intricate and comprehensive knowledge about entities, collections of entities, and the associations among them. OWL is a logic-based language that can be processed by computer programs to assess the consistency of the knowledge or to make implicit knowledge explicit. OWL documents, called ontologies, can be shared on the World Wide Web and can link to or be linked from other OWL ontologies. OWL is part of the W3C's Semantic Web technology stack, which encompasses RDF, RDFS, SPARQL, and more.
