[Mediawiki-l] Ontology import

[Mei Wu]

Hi all!

I am trying to import Ontologies into Mediawiki. I downloaded a couple of
ontologies from the web in .rdf format and imported them using the "Import
ontologies" Special page. However, every time I hit Import an error message
appears (see below).
I am running MediaWiki 1.6.7 and SemanticMediaWiki extension 0.4.3.2. I also
added the rdfapi-php to the SemanticMediaWiki "libs" folder. It looks like
the .php script is not recognized but I do not really know what the problem
is.

Does anybody has experiences with importing ontologies and have an idea what
the cause of this problem might be?

Thank you very much!

Best,
Mei
