The convergence between business process modeling and the service-oriented architecture has created a significant opportunity for Information Technology (IT ) system integrators: they can offer effective business process outsourcing for Small Medium Enterprise s (SME )s that often cannot afford the cost of designing, provisioning, and operating their own software service bus. In this paper, we present a methodology, and a corresponding implemented system Prosero, for managing multiple customized business processes, all derived from a small set of reference models. The methodology is based upon a semantic repository. The paper focuses on the structure of the semantic repository, and explains how specific operations in the end-to-end lifecycle of outsourced business processes benefit from the semantic services the Prosero repository delivers.
