Installation instructions

Install Java

GLOW requires Java (JDK version 1.5 or higher).

Protégé comes bundled with Java. If you don't have Java, you can download a Protégé version including VM and skip this step.

Do you want to know if you have Java 1.5? Open a command prompt and type java -version. The version should read at least "1.5.0". To install or update your Java installation, download and run the Java installer at the Java download site.

Install Protégé 4.0

Protégé is an ontology editor. GLOW runs as a plug-in for Protégé. Only Protégé 4.0.x is supported at this point.

Download a Protégé 4.0.x installer here:

• Protégé download site

Install JOGL 2.0

JOGL is a library that allows Java programs to use advanced OpenGL graphics capabilities. The newest version is currently still in development, but is already very stable for general use.

Since there are no easy installers yet, we provide installers for Windows here:

• JOGL 2.0b10 for Windows 32 bit
• JOGL 2.0b10 for Windows 64 bit

Note: The architecture (32 bit or 64 bit) should match the Java JVM you are using for Protégé!

After installation of the libraries, reboot your system.

For other platforms, choose one of the JOGL downloads. If you only want to build JOGL OSGI's rather than run GLOW, and your platform is not listed, you can usually pick the Linux version.

Install GLOW

Download and run the GLOW installer:

• GLOW for Windows

For other platforms, see the latest snapshot and place the JAR files in Protégé's plugins directory. Protégé will detect them automatically.

Open GLOW in Protégé

You should now be able to run the GLOW plug-in from Protégé.

• Start Protégé.
• Open an ontology of your choice.
• Go to the Classes tab.
• Go to the View | Class Views menu and choose GLOW Visualization.
• Choose a position for the visualization window, for instance on the bottom right.

Note: please check here for Running GLOW on Unix systems, such as Mac OS X, Linux and FreeBSD.
