- Grasps essential differences between schemas for syntactic validation (e.g., XML) and for inferencing (RDF Schema).
- 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 that OWL Full supports all available constructs and is most appropriately used when reasoning performance is not a concern.
- Understands the principles and practice of inferencing.
- 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.
