Re: [rules-dev] scorecard metaphor in drools?

manstis:
I have looked at drools-chance, and my understanding  is that this module is
closely tied to PMML file format, I was more looking for a generic score
models (additive/weighted/...) that can be defined using excel (and at some
point through a custom UI). 

laune:
I agree that this is not a core "engine" functionality, and can be built on
similar lines as the decision tables module. My original question was not
phrased properly :(

Now that we have covered the basics of my question, can either one of you
point to any work/discussion in the drools community in this direction?
Also, if I have some thoughts on this subject (creating this framework), who
would be the person(s) to brainstorm? Who would provide me with a go/no-go
for working on this?
