Protege Desktop Frequently Asked Questions
This FAQ is specific to Protege Desktop, versions 4.x and above.
If you're working with older versions of Protege, you might find the following alternative FAQs helpful:
How do I install Protege-OWL?
Protege-OWL is available for download from the main Protege website. If you are new to Protege-OWL, we ask that you read about the three different installation options currently available to determine which best suits your needs:
- InstallyAnywhere platform independent installer program - this is the recommended method of installation for beginners and also for users that want a "double-clickable" executable file. The primary reason we recommend this method for beginners is that Protege-OWL requires a 1.6 version of the Java Virtual Machine to be present. The installer makes it very easy for you to install the correct version of the Java VM - or - if you already have Java installed, you can indicate the location during the install process. The installer also provides an executable file that you can double-click to launch Protege-OWL, e.g., "Protege.exe" on Windows, etc.
- ZIP file - we provide a ZIP file for more advanced users that are familiar with how to make sure the proper version of Java is present. This is also a convenient installation for users that do not require an executable file to launch Protege-OWL.
- Application bundle file - this is a new offering in Protege 4.1 and above that we hope will be an improvement for OS X users.
Note that if you are new user, we ask that you register before downloading Protege-OWL. If you have already registered, simply click on the download link and navigate to the Protege 4 section of the download page.
Where can I find user documentation for the Protege-OWL editor?
Please refer to the Protege 4 documentation page on this wiki for a list of available documentation.
Where do I ask questions and report bugs?
Please post comments, questions, and bug reports on the protege-user mailing list. Note that you must be subscribed to the list in order to post messages. If you have difficulties subscribing or unsubscribing from protege-user, please contact the list owners.
Where can I look at a list known bugs and feature requests?
Visit our issue tracker on GitHub: https://github.com/protegeproject/protege/issues?state=open.
If you see this error when trying to use OWLViz, it means that you have not completed some of the necessary steps to configure this plug-in. Complete documentation for fixing this error is available in the troubleshooting section of the OWLViz documentation.
How do I change the name of an entity (class, property, individual) in my ontology?
Select the Refactor | Change entity URI... menu item. In the resulting Change entity URI dialog box, enter the new name in the text box, and click the OK button.
Why does my ontology contain classes named Error1, Error2, ...?
See the Error Classes page for a description of this new OWL API feature.
How do I edit/use SWRL rules in Protege 4
- Create a new tab (Window -> Views -> Create new tab...) called something like Rules, SWRL or whatever you prefer [OPTIONAL]
- Select the Window -> Views -> Ontology views -> Rules menu and drop the "Rules" view in a tab (for example the one created in the previous step)
- Different reasoners have different level of support for rules. Pellet has the best support for SWRL rules. If you don't see Pellet listed in your Reasoner menu, install it (Open Files -> Preferences, select Plugins tab, press on "Check for downloads now" button, select and install Pellet)
- In the Reasoner menu select the the Pellet reasoner [IMPORTANT]
- View/Create/Edit/Delete SWRL rules in the "Rules" view
- Start (Reasoner -> Start reasoner) or synchronize (Reasoner -> Synchronize reasoner) the reasoner (you can also do it with CTRL+R or COMMAND+R on Mac)
- See results of the execurted rules in you other views
