Protege 4.1 Alpha

This alpha version of Protege 4.1 is the first Protege release that is fully conformant with OWL 2.0. The OWL 2.0 language specification only recently became a recommendation on October 27, 2009.

Starting with the Protege 4.1 release, it is our intention to utilize Protege's automatic update mechanism to distribute new features and bug fixes. We hope that this will allow us to be more responsive to issues reported on the Protege 4 mailing list, and result in faster progress toward a stable release of Protege 4.1.

We have also made some changes to the format of the distribution:

  • We are providing the OS X community the ability to download Protege in the application bundle format.
  • The platform-independent installer program has been designed so that it is compatible with use on a multi-user operating system. This means that an administrator can install a single read-only copy of Protege on a system that will be used by many users sharing access to the system.

For developers, this version of Protege is based on version 3.0.0 of the OWL API, which is the first released version of the OWL API that is conformant with OWL 2.0. Version 3.0.0 of the OWL API has some incompatibilities with version 2 of the the OWL API. As a consequence, plug-ins developed for Protege 4.1 will not be backwards compatible with Protege 4.0.*. It is recommended that new development be done against the 4.1 version of Protege as this is the focus of future work.
