Based on experiences gained from an embedding of the Object Constraint Language (OCL) in higher-order logic [3], we explore several key issues of the design of a formal semantics of the OCL. These issues comprise the question of the interpretation of invariants, pre- and postconditions, an executable sub-language and the possibilities of refinement notions. A particular emphasize is put on the issue of mechanized deduction in UML/OCL specification.
