Hi James,

I think bringing in MUST and SHOULD makes the definitions much more 
rigorous. Your definition has nicely implied a set of validation rules 
for provenance logs:)

But I am not sure whether this level of rigor should happen when we 
implement the model using semantics or now, when defining the concepts.

A question to the chairs and others:

How rigorous do we want to in concept definitions?

cheers,

Jun
