Install note

Until easyrdf/easyrdf package will get stable 1.0.0 release, the root Composer file will have to explicitly require easyrdf/easyrdf. See this issue for details: easyrdf/easyrdf#320. After EasyRDF will be stabilised, the library will be moved back to require section.

Tasks

Query

$query1 = 'SELECT ?s ?p ?o WHERE { ?s ?p ?o } LIMIT 100';
$query2 = '...';

$result = $this->taskSparqlQuery()
    ->setEndpointUrl('http://example.com/sparql')
    ->addQuery($query1)
    ->addQuery($query2)
    ->run();

// Result of $query1.
$res1 = $result->getData()['result'][$query1];
// Result of $query2.
$res2 = $result->getData()['result'][$query2];
