1.  Introduction

   [RFC2731] defines "Encoding Dublin Core Metadata in HTML".  Newer
   specifications published by the Dublin Core Metadata Initiative
   ( over the last decade, in particular
   "Expressing Dublin Core metadata using HTML/XHTML meta and link
   elements" ([DC-HTML]), have obsoleted this work.

      Note: Implementers of RFC 2731 should note that DC-HTML introduces
      a new requirement with respect to the use of the "head" element's
      "profile" attribute.

2.  Security Considerations

   This document is of administrative nature only and therefore there
   are no security relations related to it.
