Event-based systems are made of reactive components that cooperate by exchanging information and control in the form of events. The occurrence of an event, as well as the data characterizing that event, may trigger the execution of one or more components, which may in turn generate other events. In a distributed event-based system, where components are physically distributed over a network, events must be signaled to remote components through some form of communication mechanism. This workshop is about (1) the engineering methods that support the design of event-based applications, and (2) the design of the communication mechanisms that support the event-based interaction of components over a network.
