Verification for commitment-based web service protocols

摘要

We propose a model for a class of web services which are powered by relational databases and annotated by social commitment. Our model can be viewed as an extension of WSDL specification where schemas of service operations specify not only input-output signatures but also data constraints, control-flow constraints, state/output/effect rules. The data-aware temporal properties about interactions between services and users are specified in Linear Temporal First-Order Logic with Social Commitment (LTL-FO~(SC) ). We have proved it is possible to use existing tools (e.g. WAVE) originally designed for verification of web applications to verify such properties.
