The need for cooperation between an ever increasing number of distributed information clients has led to the development of a broad number of tools and theories in the field of the semantic web. As a consequence, also several middleware systems have been extended to support these semantic data formats and knowledge integration techniques. However, all these middleware systems implement semantic extensions of their original communication model, but they do not employ the concept of knowledge as an integral part of the interaction metaphor. This often necessitates writing unnatural programme code, results in redundantly transferred data and leads to inconsistent interpretation of knowledge. In this paper, we present a semantic event notification service that addresses this problem by defining an event as the change of knowledge. We describe the communication mechanisms of the system and show how they are employed for implementing knowledge-driven coordination tasks. We also provide an architecture overview of our implementation and present first performance and scalability results.
