A Mediator-Based Approach for Process Mediation of Web Services

Although several efforts were made to support the standardization of Web Services (such as WSDL, UDDI, SOAP, BPEL, etc.), they are not always perfectly compatible to each other due to the distributed nature. Both data and process heterogeneity required and offered by services' requesters and providers hamper the usability of Web services, thus service mediation becomes one key working area in SOA. While the former has received considerable attention, process mediation is still open and current approaches provide only partial solutions.
