Cannot load media resource annotation ontology

Hi Vitalis/Steffen,

I am trying to visualise an ontology (http://www.w3.org/ns/ma-ont#) on WebVOWL, however, it seems that the ontology is not being dereferenced by the application. This is the error that I am getting: There is no OWL input under the given IRI(http://www.w3.org/ns/ma-ont). Please try to load the OWL file directly.

I think the problem is not entirely WebVOWLs fault, as the namespace (strangely enough) gives a 200 OK for the ontology’s turtle file. Nevertheless, asking for the rdf+xml of the namespace (curl -H "Accept: application/rdf+xml" http://www.w3.org/ns/ma-ont#), the RDF serialised file is returned. Therefore, I think that your application should by default ask for the RDF file, if turtle is not supported.

Cheers, Jer

@jerdeb and @jo-tud: looks like this issue has been resolved as both your ontologies can now be loaded by the public WebVOWL instance (i.e.: http://www.w3.org/ns/ma-ont# and http://ethon.consensys.net/EthOn.ttl). The third one (http://lov.okfn.org/dataset/lov/vocabs/frappe) still causes an error though (see my comment above).

@christopheralcock: URL parameters have been added to the latest version - see WebVOWL 1.0.6 and try the new “Export as URL” feature.

Missing imports are now possible with the new loading indicator (results in a warning for the user, however the main ontology and found imports will be loaded )

Additional information is provided now while loading the ontology.

w.r.t the ethon ontology, the server configuration results in the error code 403 also protégée is not able to load it form the url.

the same issue seems to be with the frappe ontology.

Closing this issue 😃
