Open Source based Rules Engines in Java or Python [closed]

Answer 1

I really like the simplicity of business-rules, you can always add an API layer like REST on top of that.

Answer 2

Take a look at durable_rules. It's a very state-of-the-art rulebased system for various languages, including python. I don't know if it's meeting your requirements but it's really worth a look ;)

Answer 3

Late to the party, but anyone reading this now should certainly be looking at drools if they are interested in a java based BRMS.
