This document is meant to provide discussion and examples of how to create useful ontological constructs using the Web Ontology Language OWL. Unless otherwise noted, all language elements will be at most OWL DL in order to have confidence in the computability of OWL-based models built following this methodology. While OWL has an abstract syntax, this document assumes the OWL syntax built on RDF, albeit the abbreviated form . (See the RDF Primer for more information on RDF syntax.)
