I have this error when trying to import Event ontology with URL setting to Omeka S 2.0.2


No parser class available for format: n3

It works without error when downloading the n3 file and importing the ontology with a file.

EasyRDF, the library we use for handling RDF files, doesn’t support importing from n3 formatted files. The difference when using an upload, I think, is that EasyRDF is guessing the format as Turtle (as n3 and Turtle are very similar).

You can manually select the format when importing an RDF file, so picking Turtle could work (assuming the n3 file doesn’t actually use any of n3’s features).
