DbPedians, I hope you all will take a look at RIF (the Rules Interchange Format). I believe it will prove to be very useful for linked data applications. It has reached a stable form now as a standard, and we are making a last call for comments.
The spec appears in six documents, described below. I think the Core and RDF&OWL documents will be of most interest to the LOD community. Please have a look and send feedback to [email protected] ------- W3C Press Release July 3, 2009 W3C Announces Rules Standard for the Semantic Web 2009-07-03: The Word Wide Web Consortium (W3C) Rule Interchange Format (RIF) Working Group [see: http://www.w3.org/2005/rules] has announced a Last Call for comments on stable versions of three rule dialects for the Semantic Web: Basic Logic Dialect (BLD): [http://www.w3.org/TR/rif-bld/] is a dialect for rules interchange between logic-based rule languages. RIF-BLD is an extension of Horn logic including equality, functions, datatypes, built-ins and compatibility with established semantic web standards like RDF and OWL. From a rule language perspective, BLD was designed to capture the intersection between logic programming and first-order languages, and to be extendable to more expressive languages. Production Rule Dialect (PRD): [http://www.w3.org/TR/rif-prd/] is a dialect for rules interchange between commercial production rules systems. RIF-PRD was designed to capture the intersection between known production rule systems while maximizing overlap with RIF-BLD. Core Dialect: [http://www.w3.org/TR/rif-core/] is a very simple dialect that captures one possible set of features in common between production rule and logic-based rule systems and the semantic web. All dialects have a normative XML exchange syntax and support for XML Schema Datatypes. In addition to these three rule language dialects, RIF has published three other companion documents: RIF and OWL Compatibility (RDF+OWL): [http://www.w3.org/TR/rif-rdf-owl/] describes the details of using RIF Core and BLD with the semantic web standards RDF and OWL-2. RIF Datatypes and Builtins (DTB): [http://www.w3.org/TR/rif-dtb/] describes the extensive datatype support and associated builtin functions and predicates for them. RIF Framework for Logic Dialects (FLD): [http://www.w3.org/TR/rif-fld] describes a framework for extending RIF-BLD to more expressive rule dialects that include e.g. negation, non-monotonic features, full first order logic, etc. The RIF Working Group requests comments be sent to [email protected] by 31 July 2009. -- Dr. Christopher A.
