Contextualization - Add meaning to events

A key advantage of event-based systems is that communication between producers and consumers is anonymous and light-weight. This implies that producers of event notifications cannot tailor the content to the needs of consumers. Furthermore, producers do not even know if there actually is a consumer receiving their publications. Thus, they risk doing uncessary work if they try to compensate.

Our research tackles this problem by enhancing the middleware with additional functionality. One aspect is context mediation to allow for easy interoperability between producers and consumers. Other functionality deals with policy-driven addition of external information.
