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,
Charles N=E9pote

Hi Charles,
This seems to be caused by a bug in RAP. Here's a snippet from model/=20
Model.php:
function & getOntModel($vocabulary) {
require_once( RDFAPI_INCLUDE_DIR . PACKAGE_ONTMODEL);
return new OntModel(& $this, $vocab);
}
The problem is $vocabulary/$vocab, the fix should be obvious.
You could fix it in your own copy of RAP, or set up the OntModel =20
directly, without using getOntModel.

Ok. I made the fix :
function & getOntModel($vocabulary) {
require_once( RDFAPI_INCLUDE_DIR . PACKAGE_ONTMODEL);
return new OntModel(& $this, $vocabulary);
}
But that doesn't change anything (exactly the same error). Are you sure=20
my code is correct... I won't bet on it...

How ?
Thanks Richard for your help.

Sorry, you're right ... I assumed that it was just the simple =20
spelling error in the method, but the problem is somewhat more =20
complicated. There's some code missing from the method. I'm working =20
on a fix.

Looks good to me.

I meant just put the (fixed) two lines of getOntModel into your own =20
code, but as we know now, that doesn't work.
Here's another thing you can try: Create the OntModel with =20
ModelFactory::getOntModel(DBMODEL, RDFS_VOCABULARY) instead of =20
$dbModel->getOntModel(RDFS_VOCABULARY). You'll have to find out how =20
to initialise the database connection in constants.php though.

Charles, a fix is in CVS now. (Tobias gave me CVS commit access, =20
yay!) When you update RAP from CVS, your code below will (hopefully!) =20=
work.
