Sorry, the format.

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

This query works, but from a remote SPARQL client program (Twinkle [1]) I need 
to define “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

I have tried with
FROM <http://dbpedia.org/data/Scientist.rdf> 
But no.

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.
