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.
In REF , user's requests and compositions of web services are statically modelled via constraints.
