RDF Property

Label: described by

Defined in: http://www.w3.org/TR/powder-dr/#semlink

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
