Previous lessons in this module introduced both RDF Schema and OWL as data modeling languages for describing RDF data. So which should you use? This article compares the two languages and offers the opinion that, although each has its place in the Semantic Web world, in general you should be using OWL.

- 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
- 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 that resources are declared to be members (instances) of classes using the property rdf:type.
