Jim, can you explain what you mean by "web rules" here? As I tried to explain in: http://lists.w3.org/Archives/Public/public-rif-wg/2006Feb/0105.html our primary interest is in a language which would enable people working with semantic web data to use rules. This would include people expressing rules which they are explicitly publishing for others to use but also includes people just using rules within a system which is consuming and producing semantic web data. This is analogous to query. There is value in the ability to send SPARQL queries to remote sources but some SPARQL queries will only ever get used within a given system yet the value of standardizing the language for those is still high (safe-guarding investment, encourage tool provision, ability to shift between tools). We accept that it is not the purpose of RIF to define a rule language that will meet our needs. However, by requiring RDF and OWL compatibility RIF may end up providing a framework which will meet our needs as a side effect. Now the WG could decide that this desire for a side-effect is in conflict with the main goal, that the group should only be about rule exchange and have no regard to the possibility of a semantic web rule language. That would be just fine and would simplify my life considerably. So had you just contrasted "rule-based reasoning" with "rule exchange" I would understand where you were coming from. But you've left open this "web rules" bit which seems somewhere between the two. So what do you mean by "web rules"? Dave
