      For those who gather information about news (and NewsML) related
      initiatives, a new spec called ENT (Easy News Topics) offers a simpler
      alternative to XTM (Topic Maps) for topic integration in RSS2.0
      descriptors. It relies on the idea that RSS "RDF based taxonomy module"
      (2000) wasn't broadly used because of its "perceive complexity"...

      http://www.purl.org/NET/ENT/1.0/

      The result is somewhat close to NewsML TopicSets:

      Example:
      <item>
      <title>
      <link>http://www.example.org/blog/2003/04/08.html#a855</>
      <guid>http://www.example.org/blog/2003/04/08.html#a855</guid>

      <ent:cloud xmlns:ent="http://www.purl.org/NET/ENT/1.0/"
      href="http://matt.blogs.it/topics/resources/topicRoll.opml">
      <ent:topic ent:id="sf_giants">San Franscisco
      Giants</ent:topic>
      </ent:cloud>
      <ent:cloud xmlns:ent="http://www.purl.org/NET/ENT/1.0/"
      href="http://www.examples.com/mlb.xtm">
      <ent:topic ent:id="barry_bonds"
      ent:classification="player">Barry Bonds</ent:topic>
      <ent:topic ent:id="ray_durham"
      ent:classification="player">Ray Durham</ent:topic>
      <ent:topic ent:id="felipe_alou"
      ent:classification="manager">Felipe Alou</ent:topic>
      </ent:cloud>
      </item>

      Mapping ENT -> NewsML
      ----------------------
      cloud -> TopicSet
      @href (href to a TopicMap or other topic list)-> no NewsML equivalent
      topic -> Topic
      @id -> FormalName
      @classification -> TopicType
      @href -> @Details
      content (display name) -> Description

      remark
      -------
      This spec does not offer multiple language description or id variants
      (via schemes), as NewsML TopicSet do.
