Sureth, perhaps you're hitting query time-out or hard-coded limits. Have you considered loading DBpedia yourself, rather than using the public endpoint. Incidentally, your query can be rewritten in SPARQL 1.1 as CONSTRUCT WHERE {?film a <http://dbpedia.org/ontology/Film> } If you'd like to learn more about SPARQL please do consider spending some time with the EUCLID learning materials, where this shortcut is already mentioned (and will be covered in the Querying chapter, whose webinar is on the 4th): http://www.euclid-project.eu/modules/chapter1 Barry On 12/02/13 13:40, Suresh Partha wrote: > I am makinng following CONSTRUCT Query in DBPedia.
