applications and other rule engines (between rule languages with compatible semantics) ? A rule is (just another) data item

A set of dialects and an extensible framework, encouraging interoperability

? A RIF-Core dialect with the expressive power of Datalog ? Two extensions: Basic Logic Dialect and Production Rule Dialect ? An extensive set of built-in data types, functions and operators ? Combination with RDF, OWL and XML/XSD data sources and data models
