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.
