The Web Ontology Language OWL is used for publishing and sharing ontologies on the World Wide Web, and is endorsed by the World Wide Web Consortium. OWL 2 was released as a Recommendation in October 2009. OWL is considered one of the fundamental technologies underpinning the Semantic Web and is designed for use by applications that need to process the content of information instead of just presenting information to humans. Among other things, OWL facilitates greater expressivity than XML, RDF, and RDF Schema (RDF-S) by providing additional vocabulary along with a formal semantics.
This guide contains a brief and informal description of the OWL language constructs and is meant to serve as a reference for users who want to build ontologies using OWL.
The following page we give an overview over all available OWL 2 language features and indicate if an how you can to find, access, and enter them in the NeOn Toolkit.
