 Identifier: A Link Relation to Convey a Preferred URI for Referencing
                    draft-vandesompel-identifier-00

Abstract

   This specification defines a link relation type that is intended to
   convey that a URI, other than the URI that provides a link with the
   relation type, is preferred for the purpose of referencing.

   persistent over time.  Currently, there is no link relation type to
   convey such alternative referencing preference; this specification
