ORDBase: A Common Architecture for Web Ontologies, Rules, and Data

The ORDBase architecture is introduced as a common platform for Web ontologies, rules, and data. The ontology base (here using OWL) is well-suited to represent structured knowledge. The rule base (here using RuleML) is the key to inferencing, whose predefined rules serve for translating the OWL semantics, also user-defined rules are considered. The database (here using SQL) provides for fast retrieval following the RDF data model of (subject predicate object) triples. Knowledge can be entered, queried, and derived with the ORDBase suite of tools provided as an open toolbox in Java.
