This isn't making sense to me.  In your phrasing, you suggest that a primary 
source is a derivation.  But surely, a derivation *is* a relation?  What else 
can it be?

My trouble with your phrasing is that when you make claims about "primary 
source" you make claims about an original that pretty much by definition is not 
derivative.  I think what you are trying to describe is a *relation* between 
some entity and a primary source, which is something else.
