I have a DAV folder called "foobar" set as a rdf_sink, i.e with a virt:rdf_graph set and a virt:rdf_sponger set to "on". I have uploaded several .owl files to that folder with the Webdav feature in Windows. Unfortunately, Virtuoso considers these files as octet-stream. Even if I change their mime-type after the upload, the sponger does not trigger.
Is there a way to trigger the sponger to index these (newly-typed) files? Plus, is there a preferences to set the mime-type of .owl files to (let's say) application/rdf+xml ? Any help is welcome.
