[Rdfapi-php-interest] Querying Sparql end point...

[<mai...@st...>]

Hi all,

I've been trying to run simple SPARQL query with
Sparql endpoint and SparqlClient (RAP-0.95/PHP5).

The query is a simple SELECT... doesn't give the result in array but errors our
with the message
"unable to parse result".

But the query output is dumped as a long string following the error message.

Here is the code snippet...

<?php

/**
 * @author thanh
 * @copyright 2008
 */
 // Include all RAP classes
define("RDFAPI_INCLUDE_DIR", "../rdfapi-php/api/");
include(RDFAPI_INCLUDE_DIR . "RdfAPI.php");

echo "<b><font color=blue> test 2!
(Anwendung des SPARQL client:demo.ontowiki.net/service/sparql) </font></b><br
/>";
echo " ";

####################################################
# searchPeople
# sucht nach der Person oder FALSE zurück
####################################################

 $client =
ModelFactory::getSparqlClient("http://demo.ontowiki.net/service/sparql");

 $querystring = '
	select DISTINCT (?o)
	where
	{?s ?p ?o.}
	 LIMIT 20 ';

$query = new ClientQuery();
$query->query($querystring);
$query->addDefaultGraph("http://data.semanticweb.org/dumps/conferences/iswc-aswc-2007-complete.rdf");

$result = $client->query($query);
print_r($result);

?>

Am I missing something so obvious here? Can someone help me to fix that problem?

Thanks.

Regards,
Thanh.

Yes, I send an email two month ago to tell the dev that RAP 0.95 is buged
with SPARQL. No answer yet.
