The syntax does not matter. It's abstract data model of triples in a graph that matters.  How they came to be there is not important.  RDF/XML, Turtle, GRDDL, RDFa, API inserts, private syntax, - all the same.  SPARQL/Query does not get involved (a FROM is a HTTP GET and there is content negotiation).

It's triples all the way down.
