drools

I’m trialling expert systems, in order to abstract away some tricky internationalization logic in an IVR application. Drools Expert might be what I need and will hopefully save time, compared with devil-in-the-details DSLs. The idea of a Rules Engine is that business rules are abstracted out of your application. Business rules are likely to change, so ideally they should not be in the source tree. Additionally, rules may be consulted or modified by business users, so ideally would be free from syntactic mess, and should be self-documenting.
