      Not exactly. See http://schema.org/docs/datamodel.html for the mapping
      in RDFa 1.1. The post acks the fact that you have 3 technologies
      available (microformats, rdfa and microdata) and that search engines use
      to handle those three. This will not stop. Microdata is not a
      recommendation, and it is very controversial in HTML5. RDFa is much more
      stable from my point of view, and more importantly, _extensible_.

      I personally see schema.org as another vocab to establish mappings to do
      ... and I have started to do so.
