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.
