   cite-as: A Link Relation to Convey a Preferred URI for Referencing
                      draft-vandesompel-citeas-03

Abstract

   A web resource is routinely referenced by means of the URI with which
   it is directly accessed.  But cases exist where referencing a
   resource by means of a URI, different than that access URI, is
   preferred.  This specification defines a link relation type that can
   be used to convey such a preference.
