I have some of the same concerns as Satya around the idea of
wasGeneratedBy, used, et al. being described as instantaneous events.

1) The use of an entity and generation of an entity are not instantaneous
things (although they can be recorded as such), but are things that occur
through time.

2) Calling these things events results in the sort of confusion that we are
seeing from Satya. The Activity is the event, and should therefore be
called Event.

3) Relying on terminology from process algebra is fine for people who are
familiar with it, but we want to provide that sort of theoretical
foundation to those who are not familiar with those term uses, and would
find the distinction between "event" and "activity" less then helpful.
