Combining SWRL rules and OWL ontologies with Protégé OWL Plugin, Jess, and Racer

The presentation concerns a draft implementation with Protégé OWL Plugin for SWRL, based on the RDF concrete syntax of the SWRL proposal. A first prototype of a SWRL Tab Widget has been achieved. It is a bridge between Protégé OWL, Racer, and Jess, intended to help reasoning with SWRL rules combined with OWL ontologies. A small example is given including an OWL ontology representing the family usual relationships, and a SWRL rule base representing the dependencies between those relationships. The goal is to illustrate that a key requirement is to interoperate between SWRL rules and OWL, not only syntactically and semantically, but also inferentially to get all the inferences.
