Re: [Rdfapi-php-interest] OntModel

[Richard C. <ri...@cy...>]

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.
