This primer provides an approachable introduction to OWL 2, including orientation for those coming from other disciplines, a running example showing how the language can be used to represent first simple information and then more complex information, how it manages ontologies, and finally the distinctions between its various "flavors".

- Correctly uses sub-class relationships in support of inference.
- Correctly uses sub-property 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).
- 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 role of formally declared domains and ranges for inferencing.
