Yes, we've got a table of organization-to-OrgID, particularly since one organization will have different OrgIDs not only within one RIR, but in different RIRs, even. My only point was that it's a lot easier to get data back into a database if it came out of a database in the first place. Then all you have to do is understand the relationship model between the objects, and understand what limitations it has and how it maps into one's own superset of that. -Bill
