OWL and rules

Abstract. The relationship between the Web Ontology Language OWL and rule-based formalisms has been the subject of many discussions and research investigations, some of them controversial. From the many at-tempts to reconcile the two paradigms, we present some of the newest developments. More precisely, we show which kind of rules can be mod-eled in the current version of OWL, and we show how OWL can be extended to incorporate rules. We finally give references to a large body of work on rules and OWL.
