Abstrakt

The language CspCASL combines specifications of data and processes. We give an institution based semantics to CspCASL that allows us to re-use the institution independent structuring mechanisms of CASL. Furthermore, we extend CspCASL with a notion of refinement that reconciles the differing philosophies behind the refinement notions for CSP and CASL. We develop a compositional proof calculus for refinement along the CASL structuring mechanisms, and demonstrate that compositional proof techniques along parallel process composition from the context of CSP lifts to structured CspCASL specifications.
