title: DBpedia.org Ontology versus Schema.org Ontology
body: <p>First off, I'm trying to define database tables with attributes from Schema.org, eg., for example I have a table named "JobPosting" that more or less has the same attributes as those defined in <a href="http://schema.org/JobPosting" rel="nofollow">http://schema.org/JobPosting</a> (baseSalary, etc.,), same goes for another table named "Organisation"</p>
  
  <p>I have recently come across dbpedia.org (<a href="http://dbpedia.org/ontology/Organisation" rel="nofollow">http://dbpedia.org/ontology/Organisation</a>), the schema details seem to be much more richer, but I'm am confused as to: </p>
  
  <ol>
  <li>Is dbpedia.org ontology an extension of those listed in schema.org? </li>
  <li>Are dbpedia.org schemas recognized by major search engines (as those from schema.org)</li>
  <li>What's the difference between Microdata and RFDs? </li>
  </ol>
  
  <p>I'm going a little stir crazy trying to find the details...I couldn't find any comparisons vis-a-vis dbpedia.og vs schema.org. </p>
