RDF Concepts states
	The expressive power of RDF corresponds to the
	existential-conjunctive (EC) subset of first order logic [Sowa].

How can
	takes(John,book,school)
be represented in RDF?

How can 
	loves(John,spouse(John))
be represented in RDF?

How can the RDF and RDFS semantic conditions be represented in the
existential-conjunctive subset of first order logic?
