[protege-discussion] Protege fails to open project on linux

Normally, Protege does tell you what went wrong. The RDF Backend is a 
very old implementation and it is not maintained anymore, that is why 
error reporting is not good, and we also do not plan to add any 
enhancements to it.

To edit RDF(S), it is recommended to use the Protege-OWL backend.
