+0. I like more "expiration", but depending on the context it might not be
appropriate. Can an entity
be generated with an expiration/invalidation date, ot is this out of the
scope of the group?

One question: the proposed definition aims to formulate the start/end of
activities independently from an agent.
However, the trigger is an entity, and agents are entities. Hence, I could
still say who is responsible for start of the activity:

activity(ex:foot_race)
agent(ex:DarthVader)
wasStartedBy(ex:foot_race,ex:DarthVader,2012-03-09T08:05:08-05:00)
Would that be correct? Because it would simplify things. (You can bear
responsability to an agent if you want).
If this is the intent, then +1 (it would be nice to show it with an
example in the proposal).

+1. This avoids having "phantom agents" as the note in the proposal is
suggesting.
