Various works have been done in verifying Object Constraint Language (OCL) by translating it to formal specification language. This paper presents the process of translating OCL to Prototype Verification System (PVS) using model transformation. PVS is a formal specification language based on Higher-Order Logic and comes with a theorem prover. Two processes have been identified to translate OCL to PVS. The first process translates OCL constraint to PVS specification directly using model-to-text transformation while the second process transforms OCL to PVS model. Both processes are evaluated to identify the advantages and disadvantages. Transforming OCL to PVS model allow the result to be use for other model management operation. © 2008 IEEE.
