SWORD does not, but SWORD uses AtomPub, and Atom does: http://tools.ietf.org/html/rfc4287#section-4.2.6 4.2.6. The "atom:id" Element The "atom:id" element conveys a permanent, universally unique identifier for an entry or feed. So we need something that is universally unique, permanent, and generated before the object is installed in the repository. We need it regardless of whether DB IDs or Handles would serve for REST. -- Mark H. Wood, Lead System Programmer mw...@iupui.edu Machines should not be friendly. Machines should be obedient.
