Static Analysis Techniques for Session-Oriented Calculi

In the Sensoria project, core calculi have been adopted as a linguistic means to model and analyze service-oriented applications. The present chapter reports about the static analysis techniques developed for the Sensoria session-oriented core calculi CaSPiS and CC. In particular, it presents a type system for client progress and control flow analysis in CaSPiS and type systems for conversation fidelity and progress in CC. The chapter gives an overview of the these techniques, summarizes the main results and presents the analysis of a common example taken from the Sensoria financial case-study: the credit request scenario.
