Given your comment that 'the group is not targeted at producing a "Semantic Web Rule Language"' could you say a few words on how that differs from 'The mission of the Rule Interchange Format (RIF) Working Group is to produce W3C Recommendations for rules interchange on the semantic web', which I read on http://www.w3.org/2005/rules/wiki/RIF_Working_Group. An innocent reader untrained in W3C legalities might consider the two rather closely related. What is the key difference here? And yup, I'd second your call for Semantic Webby people to take a good long look at these specs. To be honest I fear that many have stopped tracking the RIF work due to these kinds of disclaimers, ie. people have stopped expecting the group to come up with a language that captures patterns expressed in terms of RDF data. WGs sometimes respond to encouragement as well as complaint; perhaps if people here find value in that side of the work, they can communicate this in review comments. The charter says "The Working Group will have to balance the needs of a diverse community — including Business Rules and Semantic Web users — specifying extensions for which it can articulate a consensus design and which are sufficiently motivated by use cases." -- http://www.w3.org/2005/rules/wg/charter.html I guess http://www.w3.org/TR/rif-rdf-owl/#Overview_of_RDF_and_OWL_Compatibility is a good place to start. cheers, Dan -- http://danbri.org/
