Extending REBECA to support concept-based addressing

The event-based approach is well suited for integrating autonomous components or applications into complex systems by means of exchanging events. Event-based systems need an event dissemination mechanism to deliver relevant events to interested consumers. These events encapsulate data which can only be properly interpreted when su#cient context information about its intended meaning is known. In general, this information is left implicit and as a consequence it is lost when data/events are exchanged across system or institutional boundaries. For this reason, to exchange and process events in a semantically meaningful way, explicit information about their semantics in the form of additional metadata is required. This paper presents a solution to this problem and its application to an existing open source event notification service called Rebeca.
