Thanks, I think it is already covered given that in the RDF 1.1 Concepts
and Abstract Syntax document [1], section 3.1 it says:

"The set of nodes of an RDF graph is the set of subjects and objects of
triples in the graph. It is possible for a predicate IRI to also occur as a
node in the same graph."

So I assume that an RDF node can either be subject or an object.
