This lesson provides an introduction to the most useful stuff in OWL. It is not intended to be comprehensive, but it does contain quite a few of the constructs that one is likely run into. One area in which OWL goes significantly beyond RDF Schema is that it allows one to construct some fairly complex, but useful, relationships among classes. Some of the most common building blocks for doing so are presented in this module.

- 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.
- Understands the role of formally declared domains and ranges for inferencing.
