Christoph (and others),

any Java programmer can add their own interfaces to inference engines  
to TopBraid using the provided Eclipse extension points. In fact all  
currently supported inference engines are plug-ins. I can provide some  
help if anyone wants to implement a Pellet 2 integration. While we  
cannot make this part of the product, it could then become a third- 
party open-source plugin.
