RDF data can be encoded with semantic metadata using two syntaxes: RDF Schema and OWL. After this tutorial, you should be able to: Understand how RDF data models are semantically encoded using RDF Schema and OWL; Understand that OWL ontologies are RDF documents; Understand OWL classes, sub-classes and individuals; Understand OWL properties; Build your own basic ontology, step by step.

- Correctly uses sub-class relationships in support of inference.
- 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).
- Understands how an RDF class (named set of things) fundamentally differs from an object-oriented programming class, which defines a type of object bundling "state" (attributes with data values) and "b
