Re: [rules-users] externalization of input constraints in a rule

The same principle applies, but instead of inserting a single SSN container, you insert a generic "parameters" container:- rule "rule 1" when Parameters( rule == "rule 1", $ssn : ssn, $citizenship : citizenship ) Person( ssn = $ssn, citizenship == $citizenship ) then .... If your parameters are more generic Parameters could contain a Map instead of explicit parameters and change the Person pattern accordingly. It'd be good to be able to extract the rule name in the LHS, but I don't think this is possible (anybody?)
