OWL Web Ontology Language Reference

OWL Web Ontology Language Reference: "This document gives a systematic, compact and informative description of all the modelling primitives of OWL, using the RDF/XML exchange syntax for OWL. We expect this document to serve as a reference guide for users of the OWL language.

This document is one component of the description of OWL, the Web Ontology Language, being produced by the W3C Web Ontology Working Group. The Document Roadmap section of the OWL Overview document describes each of the different parts and how they fit together. Readers unfamiliar with OWL may wish to first consult the OWL Overview document [OWL Overview], and subsequently the OWL Guide [OWL Guide] for a more narrative description and examples of the use of the language.

This document assumes the reader is familiar with the basic concepts of RDF [RDF Concepts] and has a working knowledge of the RDF/XML syntax [RDF/XML Syntax] and of RDF Schema [RDF Vocabulary].

The normative reference on the precise syntax of the OWL language constructs can be found in the OWL Semantics and Abstract Syntax document [OWL S&AS]. That document also contains a precise definition of the meaning of the language constructs in the form of a model-theoretic semantics. Notions such as consistency of OWL ontologies are discussed in that document."
