SYNOPSIS

  from rdf import
      RDFStore,
      RdfXmlParser,
      RdfXmlSerializer,
      SPARQLProtocolClient,
      TurtleSerializer,
      TurtleParser,
      sparql_query;

  let store := RDFStore.temp();
  store.install_schema();

  (new TurtleParser()).parse_string("""
  @prefix ex: <http://example.com/> .
  ex:s ex:p "value" .
  """, into: store);

  let result := sparql_query(store, """
  PREFIX ex: <http://example.com/>
  SELECT ?o WHERE { ex:s ex:p ?o . }
  """);
