Re: vocabulary simplification: two proposals to vote on [deadline, Oct 26 midnight, GMT]

Hi Luc, all.
Are the "events" going to still be present on section 2.1? I don't see very
clear the difference between "activity" and "event":
They are both involved in changing "things", but the event seems like an
instantaneous activity.

As for the votes:

   - +1 to define an entity as an identifiable characterized thing. I think
   it makes everything clear.
   - +0 to rename 'process execution' by 'activity'. I think process
   execution is clear enough, but if the rest consider that it can be
   confusing, then I'm ok with the renaming.

Thanks,
Daniel
