Process Mediation

Abstract

In this chapter the problem of interoperability of incompatible business processes consisting of semantically annotated Web services is addressed, proposing a (semi-) automated solution, called process mediation, that analyzes the potentially incompatible process models of service requesters and service providers, identifying all incompatibilities, and automatically synthesizing reconciliation plans that can be used at runtime for resolving the identified incompatibilities. Compared to the previous research, the main novelty of this work is its strong focus on dynamic scenarios common for process-based service-oriented systems operating in open or semi-open dynamic environments. The chapter covers techniques for automated incompatibilities detection and resolution, service discovery in the process mediation context, techniques for monitoring, and techniques for fault handling and recovery. Finally, it discusses the lessons learned and provides an outlook for future research directions.
