[Rdfapi-php-interest] OntModel

[Charles N. <cha...@ne...>]

Hi,

I'm not very familiar with OOP and I wonder how to use OntModel methods=20
on a DbModel. I write here an example in order to precise my context.

<?php
define("RDFAPI_INCLUDE_DIR", "/var/www/wikisem/rdfapi-php/api/");
include(RDFAPI_INCLUDE_DIR . "RdfAPI.php");
include("/var/www/wikisem/config.inc.php"); // Define $config array

$wiki =3D new Wiki($config);

Class Wiki
{
	function Wiki($config)
	{
		$store =3D ModelFactory::getDbStore(
			$config['db_engine'],
			$config['db_server'],
			$config['db_database'],
			$config['db_user'],
			$config['db_password']);
		$this->dbModel =3D $store->getModel('http://ex.net/2006/02/07');
		$this->ontModel =3D $this->dbModel->getOntModel(RDFS_VOCABULARY);
		$test =3D new=20
OntResource("http://www.w3.org/1999/02/22-rdf-syntax-ns#type");
		$sup =3D $test->listRDFTypes();
	}
=09
}
?>

produce a "Fatal error: Call to a member function on a non-object in=20
/var/www/wikisem/rdfapi-php093/api/ontModel/OntResource.php on line 402"

To test this example, RDF and RDFS have been loaded in the dbmodel=20
"http://ex.net/2006/02/07".

Thanks in advance,
