Re: PROV-ISSUE-7 (define-derivation): Definition for Concept 'Derivation' [Provenance Terminology]

Hi Luc, all
In the example c2 is also a derivation of d2, and from my point of view,
c2 could also be seen as a derivation from c1, since it is the chart taken
as reference
and corected in c2...

As for your second question, I think that if we want to be able to cover
provenance from resources, resources representations and resources state
representation, a derivation must be able to refer to all of them.

What do you think?
Best,
Daniel
