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
