SQUALL to SPARQL Translator

Your SQUALL sentence:

For every book B that some P relates to some V and whose date < 2001-01-01, P does not relate B to V.

The SPARQL translation:

DELETE {
?x1 ?x2 ?x3 .
} WHERE { ?x1 a :book .
?x1 ?x2 ?x3 .
?x1 :date ?x4 .
FILTER (?x4 < "2001-01-01"^^xsd:date) .
}

Run at DBpedia SPARQL endpoint (assuming prefixes res: for resources, : and dbo: for ontology, and dbp: for properties in addition to DBpedia namespace definitions).

Load in DBpedia SPARQL Explorer (assuming the same prefixes as above).
