Not very useful, but it shows users that you can specify query parameters
in the SERVICE <IRI>:
String queryString =
"SELECT * WHERE { " +
" SERVICE
<http://dbpedia-live.openlinksw.com/sparql?timeout=10000> { " +
" SELECT DISTINCT ?company where {?company a
<http://dbpedia.org/ontology/Company>} LIMIT 20" +
" }" +
"}" ;
Query query = QueryFactory.create(queryString) ;
QueryExecution qexec = QueryExecutionFactory.create(query,
ModelFactory.createDefaultModel()) ;
try {
ResultSet rs = qexec.execSelect() ;
ResultSetFormatter.out(System.out, rs, query) ;
} finally {
qexec.close() ;
}
Maybe something like this is better (and it should not increase the number
of questions.
I do not know if the DBPedia service supports other query parameters that
could make the example more useful/interesting.
