Abstract: In this talk, we present the theorem proving environment HOL-OCL. The HOL-OCL system is an interactive proof environment for UML/OCL specifications that is integrated in an MDE framework. HOL-OCL allows to reason over UML class models annotated with OCL specifications. Moreover, HOL-OCL provides several derived proof calculi that allow for formal derivations of validity of UML/OCL formulae. These formulae arise naturally when checking the consistency of class models, when formally refining abstract models to more concrete ones or when discharging side-conditions from model-transformations.
