[rules-users] justification

Hi people, My requirements call for some justification report functionality to go with outcomes from my expert system. To give a concrete example; I have a calculation of the early release date of a prisoner and I need a generated reasoning how this result was reached. (see this weblog entry from Diettrich Kappe for a description that is very similar to what we aim to do http://blogs.pathf.com/business_rules/2006/07/the_short_circu.html ) Have any of you implemented justification functionality? What are available hooks in drools? Best regards, Joost de Vries -- Joost de Vries
