In or out of line?

I have a controversial question hear (ok, maybe it is not that controversial)

I am thinking of using RDF instances from schema   as objects of a triple as appose to being used as predicates.
The reason I am doing that is because i want the objects themselves to have clear relationships, be extendable etc . 
But i want to check what i am doing makes sense in terms of how RDF is meant to be used .

Am I stepping out of line hear?

Keep well all
