The object involved in a distributed event system, is that the event is represented as an object.

"In the last years, event-based communication paradigm has been largely studied and considered as a promising approach to develop the communication infrastructure of distributed systems. RUBDES (Rule Based Distributed Event System) is a distributed event system that allows the use of composite events in publish/subscribe computational model. In this system, an event is represented as an object and a rule is represented as an expression or a function that is evaluated or executed depending on the occurrence of events. This paper presents the design details of RUBDES and usage of Rule Definition Language (RDL) to describe composite events and event filters."
