I totally agree that we should really let the provenance providers to 
decide by themselves when they want to determine two things are same thing.

I have thought this is the beauty of our model. And whatever definitions 
we have in the end, it should still permit providers to do so, and not 
confuse them or restrict them. It's the mechanism that we are interested 
in providing, not a define distinction for a very philosophical topic:)
