[rules-users] Rule engine comparison/due diligence

[Stephen Kestle]

Has anybody tried to evaluate the different rules engines in the 
interests of using it in their companies' technology stack?  I've got to 
do some due diligence, so need to evaluate the others.

Specifically, we're looking at a dynamic data model (not OO), and so 
that needs to be supported in some way (which I am heavily evaluating 
for drools :)).  There are plenty of other criteria, but the show 
stoppers are:

    * unable to support a dynamic data model (being able to type
      different structures with the same object base, and to a lesser
      degree being able to compose those types into other dynamic types)
    * Lack of support (either community or commercial)
    * Lack of rule management (activation and expiry dates for rules)

Also high on the list are:

    * DSL support
    * rule composition and reuse (I don't really know much about how
      this this concept plays out with rules yet)
    * Testing: the person creating the rules can write the tests, in the
      same designer
    * Auditing and understanding how the engine got to the state it's in

So far I've found about 15-20 engines.  Hopefully most of them will fall 
out of the early criteria :)

Cheers

Stephen
