Mapping SCDL/BPEL to ADA for Formal Verification of the Behavioral Properties of Service-Component Architecture

Abstract

The Service Component Definition Language (SCDL) and the Web Service Business Process Execution Language (WS-BPEL) are the standards de-facto used in the modeling and implementing of Service-Component Architecture (SCA). However, these powerful languages lack a formal foundation for the specification and verification of the SCA properties. In this study, the use of Wright formal ADL and Ada programming language was proposed to check the behavioral properties of SCDL/WS-BPEL Service-Component architectures. To achieve this, the mapping of SCDL/WS-BPEL to the Wright formal ADL was suggested in order to verify the standard behavioral consistency of the source description. As a second step, the target specification could be transformed into Ada to check the specific and dynamic behavioral properties of the SCDL/WS-BPEL source architecture.
