Hi All,

What do people think of Luc's definition of derivation:

- http://www.w3.org/2011/prov 
Things represent stuff in the real-world.

Definition of Derivation. A derivation represents how stuffs are 
transformed or affect each other in the real world.

A thing B is derived from a thing A if:

A was used (and therefore created) before B was created
The values of some invariant properties of B are partially determined by 
the values of some invariant properties of A

James you seemed to suggest another way to define derivation or not 
define it all? Can you be more specific?
