An RDF property to exactly match the describedby relationship type introduced in http://www.w3.org/TR/powder-dr/#assoc-linking and formally defined in appendix D of the same document, i.e. the relationship A 'describedby' B asserts that resource B provides a description of resource A. There are no constraints on the format or representation of either A or B, neither are there any further constraints on either resource.
