Blending event-based and multi-agent systems around coordination abstractions

While event-based architectural style has become prevalent for large-scale distributed applications, multi-agent systems seemingly provide the most viable abstractions to deal with complex distributed systems. In this position paper we discuss the role of coordination abstractions as a basic brick for a unifying conceptual framework for agent based and event-based systems, which could work as the foundation of a principled discipline for the engineering of complex software systems.
