Abstract Interaction with web services enabled marketplaces would be greatly facilitated if users were given a high level service request language to express their goals in complex business domains. This can be achieved by using a planning framework which monitors the execution of planned goals against predefined standard business processes and interacts with the user to achieve goal satisfaction. We present a planning architecture that accepts high level requests, expressed in a service request language known as XSRL. The planning framework is based on the principle of interleaving planning and execution. This is accomplished on the basis of refinement and revision as new service-related information is gathered from service repositories such as UDDI and web services instances, and as execution circumstances necessitate change. The planning system interacts with the user whenever confirmation or verification is needed.
XSRL, a language to express service requests, is presented in REF .
