This slide presentation discusses the various types of RDF Schema and OWL entailment regimes defined by SPARQL 1.1. It highlights where limitations and restrictions exist and suggests ways to make SPARQL-to-OWL queries more efficient. Options include class-property hierarchy exploitation, as well as exploiting domain and range restrictions. Very complex stuff- a version with audio would be most helpful.

- 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.
- 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 common entailment regimes and understands their uses.
