You can try to use drools-verifier. This project basically lets you define rules about your rules. 

You can have a look at its tests to see how it works.

You can get more info about drools-verifier here: http://community.jboss.org/wiki/DroolsVerifier

And here you can see how are we using drools-verifier inside Guvnor: http://ilesteban.wordpress.com/2010/04/05/guvnors-field-constraints/

Hi there everybody,

I need to perform rule comparison on a project I'm working on using drools expert 5.0. For a specific feature implementation, I have two different knowledge bases with several rules which I need to compare, one by one. By comparing, I mean "inspect" certain conditions within the LHS.

Currently, I'm able to obtain several attributes from rules (org.drools.rule.Rule), such as the agenda-group and the rule name and a few others, but I haven't been able to do it all. Going deeper, there is LiteralConstraint (for simple conditions) which I can parse and obtain data. However, I don't know how to do it for OR-conditions, which I guess represents a MultiRestrictionFieldConstraint. Perhaps there is another way?

I know this may seem like a very unorthodox thing to do, but I don't think there is a better way of comparing knowledge packages (except for full text comparison). Is there?

Thanks in advance,

_ miguel, PT
