Challenges (Research Issues) in Web Services

The Web services paradigm promises to enable rich, flexible and dynamic inter-operation of highly distributed and heterogeneous applications using Web standards. The ability to discover, select and compose inter-organizational and heterogeneous services available on the Web at runtime in order to facilitate application reuse is an interesting problem in Web services. An effective mechanism for discovery, selection and composition of Web services, based on the requester´s complex functional and nonfunctional requirements is still an issue of open research. In this paper, authors explore the major Challenges (open problems) related to Web service description, discovery, selection and compositions.
