      Linkset: Media Types and a Link Relation Type for Link Sets
                         draft-wilde-linkset-05

Abstract

   This specification defines two media types for representing sets of
   links and a link relation type for referring to sets of links.  The
   media types can be used to represents links in a standalone fashion,
   in one case in the native format as used in the HTTP "Link" header
   field, and in the other case in a JSON-based format.  The link
   relation type can be used to point at a resource that provides a set
   of links.
