HiAttempto is a wonderful tool, and I'm trying to figure out how I can export an ACE rule base in N3 logic ( <a href="http://www.w3.org/DesignIssues/N3Logic">http://www.w3.org/DesignIssues/N3Logic</a> ) . Any hint welcome. ------------------------------------------ Let me introduce myself. I'm working on generation of a Graphical User Interface with a RETE rule engine. The projects : The Déductions project ( <a href="http://deductions.sourceforge.net/">http://deductions.sourceforge.net/</a> ) aims at using Artificial Intelligence techniques for general software development tasks. Currently we have rules in N3 language to generate simple Create-Update applications for Java Swing platform from OWL models. User Manual for the form generator: <a href="http://deductions.svn.sourceforge.net/viewvc/deductions/html/GUIgenerator.html">http://deductions.svn.sourceforge.net/viewvc/deductions/html/GUIgenerator.html</a> The Déductions project is strongly connected to the EulerGUI Integrated Development Environment ( <a href="http://eulergui.sourceforge.net/">http://eulergui.sourceforge.net/</a> ). The difference is that Déductions provides the rules and models, and EulerGUI allows one to develop and run these rules.
