The first version of ODbL hat an explicit clause about reverse 
engineering, saying that if you reverse engineer a produced work the 
resulting DB will fall under ODbL. That has been scrapped because 
lawyers said that this was implicit - i.e. you *can* indeed have a 
produced work that is, say, PD, but if you use that to re-create the 
database from which it was made, that database is protected by database 
right once again and you need a license to use it.

Otherwise, only the most obscure works (certainly not a printed map) 
could fall under the "Produced Works" rule.

Bye
Frederik
