Description

The dataset view tries to list classes with a SPARQL query that fails:

SELECT  ?class (count(?s) AS ?count)
   WHERE
     {   { ?s <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> ?class }
       UNION
         { SELECT  ?s
           WHERE
             { ?s ?a ?b
               FILTER NOT EXISTS {?s <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> ?class }
             }
          GROUP BY ?s
        }
    }
  GROUP BY ?class
