Abstract

This paper presents a middleware to help designers in theimplementation of contract-aware agent-based services. The middlewareprovides several components, including a contract manager, a communicationmanager and a workflow manager, which combine to allow agentsto manage contracts and the actions associated with them. The middlewareis built as part of a Web service implementation of the ISTCONTRACTframework. An electronic commerce example is used toillustrate how the components of the middleware facilitates the managementand execution of agreements in a contract at run-time.
