It is implemented as a shallow embedding of OCL into the Higher-order Logic (HOL) instance of the interactive theorem prover Isabelle. HOL-OCL defines a machine-checked formalization of the semantics as described in the standard for OCL 2.0. This conservative, shallow embedding of UML/OCL into Isabelle/HOL includes support for typed, extensible UML data models supporting inheritance and subtyping inside the typed lambda-calculus with parametric polymorphism. As a consequence of conservativity with respect to higher-order logic (HOL), we can guarantee the consistency of the semantic model. Moreover, HOL-OCL provides several derived calculi for UML/OCL that allow for formal derivations establishing the validity of UML/OCL formulae. Elementary automated support for such proofs is also provided top }, bibkey = {brucker.ea:hol-ocl-book:2006}, keywords = {security, SecureUML, UML, OCL, HOL-OCL, model-transformation} }
