[rules-users] Any API accessing to the rule logic instead of only Facts

[Stephen Masters]

Do your other applications log the source code of the application every time a call is made to it?

It may be better to look at what Guvnor has to offer. For instance, it provides version history of the rules, so that if you know the name of a rule (which you get from the activation details), then for audit purposes you should be able to see what that rule looked like on a particular time and date.
