hi,
inspired by this page [1] i tried to sparql
for people who managed to die on their birthday.
with this query
PREFIX xsd:<http://www.w3.org/2001/XMLSchema#>
SELECT *
WHERE {
?s <http://dbpedia.org/property/birthDate> ?bd
FILTER(datatype(?bd)=xsd:date).
?s <http://dbpedia.org/property/deathDate> ?dd
FILTER(datatype(?dd)=xsd:date).
FILTER(MONTH(?bd)=MONTH(?dd) && DAY(?bd)=DAY(?dd)) .
} LIMIT 10
i get this error [2] at dbpedia's sparqlEndpoint,
i also tried different birthDate properties that are available but the
result stays the same.
when i look at a resource's page it says the all these dates are of type
xsd:date (example : http://dbpedia.org/page/Le_Corbusier)
any pointer appreciated..
