This video lecture starts with an overview of the requirements for defining and using ontologies on the Web. It then outlines the main concepts and issues associated with the Web ontology languages, RDF, RDF Schema and OWL. By the end of this presentation viewers will have gained a basic understanding of the principles underlying OWL. Also quickly covers the basics of the RDF Data Model.

- Knows that the word "ontology" is ambiguous, referring to any RDF vocabulary, but more typically a set of OWL classes and properties designed to support inferencing in a specific domain.
- Knows Web Ontology Language, or OWL (2004), as a RDF vocabulary of properties and classes that extend support for expressive data modeling and automated inferencing (reasoning).
- Uses RDF Schema to express semantic relationships within a vocabulary.
- Knows that Web Ontology Language (OWL) is available in multiple "flavors" that are variously optimized for expressivity, performant reasoning, or for applications involving databases or business rules
- Understands the principles and practice of inferencing.
