[lanthaler]

_Raised by Stéphane Corlosquet:_

Could the following RDFa snippet by updated to be more in line with RDFa Lite?
http://www.w3.org/TR/json-ld/#rdfa

Like this:

<div prefix="foaf: http://xmlns.com/foaf/0.1/">
   <ul>
      <li typeof="foaf:Person">
        <a property="foaf:homepage" href="http://example.com/bob/">
           <span property="foaf:name">Bob</span></a>
      </li>
      <li typeof="foaf:Person">
        <a property="foaf:homepage" href="http://example.com/eve/">
          <span property="foaf:name">Eve</span></a>
      </li>
      <li typeof="foaf:Person">
        <a property="foaf:homepage" href="http://example.com/manu/">
          <span property="foaf:name">Manu</span></a>
      </li>
   </ul>
</div>
