The W3C Rule Interchange Format (RIF) Working Group has posted 6 Last Call
documents for the W3C Rule Interchange Format standard which includes a W3C RIF
Production Rules Dialect (RIF-PRD).
See www.w3.org/2005/rules/wiki/RIF_Working_Group.
Last call period ends 31 July 2009.

The mission of the Rule Interchange Format (RIF) Working Group is to produce W3C
recommendations for rules interchange. Next step will be the call for
implementations of RIF. Upcoming RIF dialects will address reaction rules for
rule-based CEP.

The new RIF standard is featured at the RuleML 2009 Conference in a W3C RIF
workshop in November 2009 (see http://2009.ruleml.org) with a keynote from
Sandro Hawke (W3C staff representative on the RIF WG) and a tutorial from
Christian de Sainte Marie (ILOG/IBM, co-chair of the RIF WG). There will be also
keynote by Paul Vincent (TIBCO CTO for Business Rules and CEP, EPTS-RA WG
Co-Chair) about “Why Rules Matter in Complex Event Processing... and vice
versa” and a keynote by Donald Chapin (co-chair of the OMG Business Modeling &
Integration Domain Task Force, co-chair OMG SBVR) about “Terminology: The
Semantic Foundation for an Organization’s Executable Rules”.

RuleML-2009 currently has an open call for demonstrations/case
studies/benchmarks/best practice reports for the 3rd Rules Challenge at
RuleML-2009 (http://2009.ruleml.org), including demos on rule-based event
processing.
