[W3C RIF] New W3C Rule Interchange Format Working Drafts

Dear Colleagues,

Rule markup languages will be the vehicle for using rules on the Web  
and in other distributed systems. They allow deploying, executing,  
publishing and communicating rules in a network. They may also play  
the role of a lingua franca for exchanging rules between different  
systems and tools. The main purposes of a rule markup language are to  
permit reuse, interchange and publication of rules used e.g., in a  
Corporate Semantic Web to represent business rules, semantic business  
process flows, regulations, and policies.

2008 sees a major step forward for rules on the Web. The W3C Rule  
Interchange Format (RIF) Working Group [1] has published several  
public specifications for a new standardized Rule Interchange Format  
(W3C RIF) which is part of the latest Semantic Web stack [2].

The Rule Interchange Format (RIF) Working Group has just published  
five new Working Drafts.  Since the Last Call Working Drafts of RIF  
Basic Logic Dialect (BLD) [3] and RIF RDF and OWL Compatibility [4] in  
July, the group has been developing other dialects, components, and  
test cases.

The new publications are:

   RIF Use Cases and Requirements (minor changes)


   RIF Core (new design to support both BLD and PRD)


   RIF Datatypes and Built-Ins 1.0 (various improvements)


   RIF Production Rule Dialect (PRD)  (operational semantics are complete)


   RIF Test Cases (early stages of test suite)


Feedback and comments from the community at large are welcome and  
should be sent to: public-rif-comments@w3.org before 23 January 2009,  
2008. All comments (and responses to them) will be available at the  
public archive [5].
