JessTab is a plug-in for Protégé that allows you to use Jess and Protégé together. It gives you the best of both worlds. JessTab provides a Jess console window where you can interact with Jess while running Protégé. Furthermore, JessTab extends Jess with additional functions that allows you to map Protégé knowledge bases to Jess facts. Also, there are functions for manipulating Protégé knowledge bases from Jess.
Using JessTab, you can develop programs that manage Protégé knowledge bases directly, and you can write rules that fire on patterns in the knowledge base. It is possible to use JessTab as an object-oriented extension to Jess by defining Protégé classes and instantiating them. Because, Protégé has explicit metaclasses you can map them to facts as well and perform pattern matching on properties of classes.
The most recent version of JessTab is 1.7. The recommended environment for JessTab is Jess version 7.0 or later and Protégé version 3.4 or later. (It may work with somewhat earlier versions of Jess and Protégé, but is has not been tested with them.)

You should put the
JessTab.jar file in the
plugins/JessTab directory under the Protégé installation. The file
plugin.properties should go in the same directory.
Furthermore, you need to obtain and possibly compile Jess if you do not have it already.
Jess must be available in the
plugins/JessTab directory. The JessTab
documentation provides additional installation instructions.
(mapclass owl:Thing)under OWL, because JessTab will map all the hidden RDF/OWL classes as well, which may result in a large amount of unwanted Jess facts and stability problems. For the same reason, avoid mapping metaclasses and metaproperties under OWL. Use an intermediate subclass of
owl:Thingand map this class instead.
The source code for JessTab is available for download (maintained as a Subversion repository).
