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.
