Title Body

I need to get data about films from DBpedia. I use SPARQL query as follows on http://dbpedia-live.openlinksw.com/sparql : PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX foaf: <http://xmlns.com/foaf/0.1/> SELECT ?subject ?label ?released WHERE { ?subject rdf:type <http://dbpedia.org/ontology/Film>. ?subject rdfs:label ?label. ?subject <http://dbpedia.org/ontology/releaseDate> ?released. FILTER(xsd:date(?released) >= "2000-01-01"^^xsd:date). } ORDER BY ?released LIMIT 20 I tried to get films that were released after 01.01.2000. But the engine answers as follows: Virtuoso 22007 Error DT006: Cannot convert 2009-06-31 to datetime : Too many days (31, the month has only 30) SPARQL query: define sql:big-data-const 0 #output-format:text/html define sql:signal-void-variables 1 define input:default-graph-uri <http://dbpedia.org> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX foaf: <http://xmlns.com/foaf/0.1/> SELECT ?subject ?label ?released WHERE { ?subject rdf:type <http://dbpedia.org/ontology/Film>. ?subject rdfs:label ?label. ?subject <http://dbpedia.org/ontology/releaseDate> ?released. FILTER(xsd:date(?released) >= "2000-01-01"^^xsd:date). } ORDER BY ?released LIMIT 20 As far as I can understand there are some errors in data in DBpedia and the engine cannot convert string data to date type in order to compare with the date I set. And the engine breaks the query execution. So, the question is: is there any way to tell the engine to skip all the erroneous data and return to me all that could be processed?
