[rules-users] fact base storage?

I'm trying to come up to speed on the drools capabilities. I see that drools supports loading rules from a decision table in a spreadsheet. I have a set of conversion tables that I'd like to represent as facts asserted when the rule base has been loaded, but before processing user requests. I could always model lookup tables in a database, but I'd rather not have to build the CRUD interface to manage them. I'd rather represent them so that each row in a spreadsheet represents a fact (based upon a predefined java bean). Of course, I could custom implement this functionality. However, I was wondering if drools supports some OOTB means of loading facts from Excel or other resource? thanks, -Jess
