Hi Khalid,
Can you expand on this? What would it help us to achieve?

At F2F1, some mentioned "turtle all way down" to refer to the idea that 
we are not trying
to make a distinction between an entity and its state (as we used to say 
then).
This would translate into the fact that we only have characterized 
entities ...
   and are not trying to distinguish an entity from a characterized entity.

Can you explain what benefits you see in distinguishing entity from 
characterized entity?

So, does it mean in the example, you would say that e1 is same entity as e2?
Potentially, this could be captured by (the very rough) definition of 
version.

I don't suggest defining that term, but having a means by which one would know that two Bobs are characterizations, possibly different, of the same entity, e.g., using an assertion like "sameEntity(bob1, bob2)".
