The main contribution of this paper is the development of a contract-based framework for coordinating web-services that are engaged in long-running, cohesive business transactions. The proposed framework offers an amplification to both traditional and reinvented flavors of E-Business ACIDity for statically ensuring e-business transaction robustness and reliability by introducing agreement (atomicity). In addition, this framework provides an agreement-driven model for dynamically coordinating web-service orchestrations.
