Towards a Semantic Event-Based Service-Oriented Architecture

Abstract. 1 Service-Oriented Architecture (SOA) is commonly lauded as a silver bullet for Enterprise Application Integration, inter-organizational business processes implementation, and even as a general solution for the development of all complex Web-oriented applications. However, SOA without semantic descriptions of its data, processes and messaging models fails to achieve a truly flexible and dynamic infrastructure. In this paper we explain where semantics are necessary for SOA and present early work on a Semantic Execution Environment which couples the Service-Oriented and Event-Driven architecture styles with formal semantics.
