Protégé has an active user community that includes research and industrial projects in more than 100 countries. We asked Protégé users to describe their projects on the Protégé Community Wiki.

If you are involved in a project of any sort that uses Protégé, we encourage you to visit the ProjectsThatUseProtege page our Wiki and add a link to your project. If you are uncomfortable editing a Wiki page, please send us an email with information about your project and we will post it on our Wiki on your behalf.
