Hi,
Sorry to bother the list, but I'm stumped by what should be a simple SPARQL
query. When applied to the dbpedia end-point [1], this search:
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX dbpedia-owl: <http://dbpedia.org/ontology/>
SELECT *
WHERE {
?pers a foaf:Person .
?pers foaf:surname "Malik" .
OPTIONAL {?pers dbpedia-owl:birthDate ?dob }
OPTIONAL {?pers dbpedia-owl:deathDate ?dod }
OPTIONAL {?pers dbpedia-owl:placeOfBirth ?pob }
OPTIONAL {?pers dbpedia-owl:placeOfDeath ?pod }
}
LIMIT 100
yields no results. Yet if you drop the '?pers foaf:surname "Malik" .' clause,
you get a result set which includes a Malik with the desired surname property. I'm
clearly being dumb, but in what way? :-)
(I've tried adding ^^xsd:string to the literal, but no joy.)
Thanks,
Richard
