HelloI'm observing a strange ( ?) behaviour on the dbpedia Sparql-endpoint, and I wonder whether this is due to the underlying data or to the Sparql-endpoint itself (virtuouso). Following the dumps of dbpedia 2014, the data seems OK though.The query select distinct * { dbpedia:Cicero <http://dbpedia.org/ontology/birthDate> ?o } Returns -043-12-07 (7^th of July 43 BC) which is what I expected. However select distinct * { ?s <http://dbpedia.org/ontology/birthDate> ?o filter(?o < "-43-01-01"^^xsd:date) } limit 100List all sorts of things (mainly persons though, but none with a birthdate before 43 BC). Browsing the dbpedia dumps I found several person born before 43 BC.Does anybody know where this error comes from ? Best regards Johannes
