    built-in primitives(noValue,remove) for user defined rules

      In jena rules, when i say noValue(?a ?b ?c), it checks triple if there is no value then rule infer new triple.
      How can we implement this in oracle rules? In oracle rules, I know the primitives can only be use in the filter part of the rule not in the head. But i don't know how to implement noValue primitive in oracle rules. Thanks for your help.
