The present paper proposes new syntactical simplification opportunities deriving from the presence in a query Language of constructa explicitely referring to structural and temporal information. The paper refers to the more general aspects of the Knowledge Representation Language Telos and treats the associated Query Language using an extension of the Predicate Calculus. The Extended Predicate Calculus supports references to the modeling aapectll which make Telos particularly expressive and extensible: structured and temporal information, attribute categories and user-defined meta attributes.
