I am working on an ontology. Suddenly, Protege closes unexpectedly. When I reopen it and open the last ontology I notice that all my classes, individuals and properties are now renamed with the prefix 'owl:'. With this my SPARQL queries no longer work. So far I've worked around it by opening an older version of the same ontology but it's a pain to manually update the old one to the new one because I simply can't find how to remove this prefix. Please help!

Sounds like a crash/bug in the desktop Protege app, which would probably be better raised to the development project.

To fix your data, you should be able to open the file in a text editor and do a search/replace - faster than renaming things manually in Protege.

yeah I tried this - renaming it all. The file still opens with the owl prefix in protege though and I can't import it into another ontology editor because it can't be parsed. very sad.
