Upgrading projects using the Graph Widget from Protege 3.3 to 3.4

This wiki article documents the process for upgrading Protege projects that use the graph widget from Protege 3.3 to Protege 3.4. Please note that this article is only applicable to OWL projects. If your project uses Frames, you do not need to perform any extra steps to upgrade.


Protege's underlying support for OWL underwent some major changes between the 3.3 and 3.4 releases. Overall, these changes are extremely positive and allow for much faster parsing, improved namespace handling, direct connection to the Pellet reasoner, etc. One side-effect of these changes however, is an incompatibility between versions in the way the graph widget reads and stores configuration data. If you have a project in Protege 3.3, it is not possible to simply open your project in 3.4 and have the graph widget function as expected. You must perform a series of manual steps (outlined below) to modify your 3.3 project in such a way that the graph widget will function properly in 3.4.


Requirements:

  • Protege 3.4.1 or above.
  • Please back up your work before proceeding.


Create a .forms file

  • Open your project in Protege 3.3 (or whatever earlier version of Protege you are using).
