Hi all,
A question?
In http://dbpedia.org/snorql/
SELECT *
WHERE {
?cientifico dbo:birthDate ?birth .
?cientifico dbo:deathDate ?death .
?cientifico rdf:type dbo:Scientist
}
ORDER BY ?cientifico
Thisquery works, but froma remoteSPARQLclient program (Twinkle[1]) Ineed
todefine “FROM”. How I can generalize the following query
PREFIX dbo: <http://dbpedia.org/ontology/>
SELECT *
FROM <http://dbpedia.org/data/Albert_Einstein.rdf>
FROM <http://dbpedia.org/data/Severo_Ochoa.rdf>
FROM <http://dbpedia.org/data/Santiago_Ram%C3%B3n_y_Cajal.rdf>
WHERE {
?cientifico dbo:birthDate ?birth .
?cientifico dbo:deathDate ?death
}
ORDER BY ?birth
Ihavetried with
FROM <http://dbpedia.org/data/Scientist.rdf>
But no.
