Abstract: In this paper we propose adopting the notion of system as the invariant element that delimits an event. We argue that it provides cohesion among the succession of situations that characterize an event and renders a clear criterion to decide which objects can be said to participate in an event at each instant.

Keywords: Ontologies, Events, Processes, Systems, Situations, Dispositions and Connections.
