Extending the Resource Description Framework (RDF) by Adding Negation and Rules

Extended RDF (ERDF) extends RDF by adding weak and strong negation, as well as derivation rules. The ERDF stable model semantics, which is based on Partial Logic, extends the classical RDF(S) semantics by allowing for both truth value gaps (partiality) and truth value clashes (inconsistency) through the consideration of falsity extensions in addition to truth extensions for each predicate (class or property). ERDF supports both closed-world and open-world reasoning.
