document: Position paper : a comparison of two modelling paradigms in the Semantic Web Classical logics and Datalog-related logics have both been proposed as underlying formalisms for the Semantic Web . Although these two different formalism groups have some commonalities , and look similar in the context of expressively-impoverished languages like RDF , their differences become apparent at more expressive language levels . After considering some of these differences , we argue that , although some of the characteristics of Datalog have their utility , the open environment of the Semantic Web is better served by standard logics .
