> I'm new in rdf and I have the mission to implement a rule > based system using rdf What do you mean by "rule based system"? Do you mean rules in the sense of 1) declarative logic programming (or deductive databases) for defining derived concepts and heuristics (without any state-changing effects)? These rules are called "derivation rules" in RuleML. 2) SQL triggers (or "event-condition-action rules") for specifying the reactive behavior of a system in response to events? These rules are called "reaction rules" in RuleML. They specify state changes in their head/consequent, and they may "call" derivation rules in their body/antecedent. 3) production rule systems like JESS? They are just another programming language based on the rule metaphor but without any precise semantics for rules. Notice that this list is only concerned with a restricted form of 1).
