title: "DESCRIBE" SPARQL query on Dbpedia
body: <p>I want to extract dbpedia data to RDF using "DESCRIBE" query.</p>
  
  <p>For instance, if i type:</p>
  
  <pre><code>PREFIX rdf: &lt;http://www.w3.org/1999/02/22-rdf-syntax-ns#&gt;
  PREFIX db: &lt;http://dbpedia.org/ontology/&gt; 
  PREFIX prop: &lt;http://dbpedia.org/property/&gt;
  DESCRIBE ?movie ?author ?genre
  WHERE { 
  ?movie rdf:type db:Film ;
  prop:author ?author ;
  prop:genre ?genre .
  }
  LIMIT 50
  OFFSET 0
  </code></pre>
  
  <p>everything works fine.</p>
  
  <p>However, if i add actor and duration properties:</p>
  
  <pre><code>PREFIX rdf: &lt;http://www.w3.org/1999/02/22-rdf-syntax-ns#&gt;
  PREFIX db: &lt;http://dbpedia.org/ontology/&gt; 
  PREFIX prop: &lt;http://dbpedia.org/property/&gt;
  DESCRIBE ?movie ?author ?genre ?actor ?duration
  WHERE { 
  ?movie rdf:type db:Film ;
  prop:author ?author ;
  prop:genre ?genre;
  prop:actor ?actor;
  prop:duration ?duration .
  }
  LIMIT 50
  OFFSET 0
  </code></pre>
  
  <p>I'm getting empty RDF.</p>
  
  <p>Here is schema for Movie: <a href="http://schema.org/Movie" rel="nofollow">http://schema.org/Movie</a></p>
  
  <p>Anyone?</p>
