Web service based applications are expected to live in dynamically evolving settings. At run-time, services may undergo changes that could modify their expected behavior. Because of such intrinsic dynamic nature, applications should be designed by adhering to the principles of design-by-contract. Run-time monitoring is needed to check that the contract between service providers and service users is fulfilled while the collaboration is in place. The authors describe a language to specify the expected functional and nonfunctional requirements that a service provider should fulfill. The language (Timed WSCoL) is a temporal extension of a previous proposal (WSCoL).
