<b>Context:</b>
Activities have a start and an end (corresponding to event defined in part II). Entities have a characterization interval, with a generation event marking the interval beginning, but no event marking the interval end.
</p>
-<p>It is proposed to introduce an explicit event that marks the end of an entity characterization interval. Some suggested that it could be a "destruction" event, others felt the term destruction is too strong, but no alternate term has been proposed so far.</p>

<b>Context:</b>
The motivation for introducing agents in prov-dm is to denote the agent's responsibility for activities. It is however impossible to describe the start/end of an activity without introducing agents, and therefore assigning responsibility.
