<div><br></div><div>I would like write a clojure DSL for drools similar to what André was trying to do and I also feel that using maps as fact-objects would be the most idiomatic for Clojure (at least in the general case!).</div>
<div><br></div><div>I am interested by the idea of implementing ObjectType and Accessor interfaces proposed by Edson. It seems that this would be a good fit with Drools and that (if understand correctly!) it would allow the map properties to be properly indexed by the rules engine. However I cannot seem to find these interfaces (ObjectType and *Accessor) in the current API.</div>
