Abstract. Interacting with a web service enabled marketplace in order to achieve a complex task involves sequencing a set of individual service operations, gathering information from the services, and making choices. We propose to encode the problem of issuing requests to a composition of web services as a constraint-based problem.
A different solution to planning service composition has been proposed in REF , where the problem of composing services in order to achieve a given goal is expressed as a constraint satisfaction problem.
