Summary: Rule languages and rule systems are widely used in applications ranging from database integration, service provisioning, and business process management to loan underwriting, privacy policies and Web services composition. General purpose rule languages remain relatively unstandardized, however, and rule systems from different suppliers are rarely interoperable.

Meanwhile, the Web has achieved remarkable success in allowing documents to be shared and linked throughout the world. More recently, Semantic Web languages like RDF and OWL are beginning to support data/knowledge sharing on the same scale and with considerable flexibility. Having a language for sharing rules is often seen as the next step in promoting data exchange on the Web.

This workshop, held by W3C with support from DARPA and hosted by ILOG, is intended to gather various participants and inputs needed to see how a standard rule framework might be developed, informed by Web Architecture and useful for addressing real user challenges.
