Well, I would say that the difference between epistemology and ontology as it is used, is the difference between truth and meaning. Ontologies are arbitrary, but epistemology is a product of the hierarchy of constant relations of the universe. To state it prosecutorially, I would say that epistemology produces a testimonial ontology, and that all other ontologies are merely fictionalisms.
