OWL (or Web Ontology Language) is the ontology (think "schema") language of the Semantic Web. It is one of the core Semantic Web standards one should be familiar with, along with RDF and SPARQL. After completing this lesson, the user will know: 1) The four main kinds of modern computing languages, and which kind OWL is; 2) Three advantages of OWL over other languages of its kind; 3) A few of the tools available for creating ontologies using OWL.

- Grasps essential differences between schemas for syntactic validation (e.g., XML) and for inferencing (RDF Schema).
- 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).
