Re: [Rdfapi-php-interest] Merging OntModels

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I have had trouble like that too. Seems like it should just work.
But, something like this seems to work for me:

$mem_model = new MemModel(MODEL_URI);  
$mem_model->addModel($infmodel->getModel());

I take the inf model and pass it to a new, general mem model using getModel.
