The RIF WG released the first public working draft of the RIF Core specification at http://www.w3.org/TR/rif-core/. The RIF Core is a very basic interchange format for rules, based on horn logic.
While this WD lays the foundation for the RIF Core, several issues remain unspecified and expected to be addressed in future drafts of the Core spec, for example:
- OWL and RDF compatibility
- How to interchange application data models used by rules
- Precisely how URIs will be used in RIF rules
- Whether and how much meta-data should be included in RIF translations, for e.g. preserving rules in “round trip” translations
