Eyeball - checking RDF/OWL for common problems
Eyeball is a Jena-based tool for checking RDF models (including OWL) for common problems. It is user-extensible using plugins.
Note: Jena Eyeball has not been released under the Apache Software License.
The source code is available at Apache.
Getting the Eyeball release
Download from SourceForge: Eyeball distribution This predates the move of Jena to Apache and is not an Apache release.
If you haven't already, download Eyeball
and unzip it into a directory of your choice. The download includes all
of Jena, so it should not require any additional
.jar files to run.
If you have Ant installed, run the Eyeball test suite:
If it doesn't say that the tests passed, please file a Jira issue

lib directory are on your
Using Eyeball with Apache Maven
Trying it out
Pick one of your RDF files; we'll call it FOO for now. Run the command-line command
java jena.eyeball -check FOO
You will likely get a whole bunch of messages about your RDF. The messages are supposed to be self-explanatory, so you may be able to go ahead and fix some problems straight away. If you get a Java error about NoClassDefFoundError, you've forgotten to set the classpath up or use the -cp myClassPath option to Java.
You may also want to try the experimental GUI, see below.
If the messages aren't self-explanatory, or you want more details, please consult the guide.
Experimental Eyeball GUI
Eyeball includes a simple GUI tool which will allow multiple files to be checked at once and multiple schemas to be assumed. It will also allow you to select which inspectors are used.
To start the GUI, use the following (assuming your classpath is set up, as above): java jena.eyeballGUI
