i don't think anywhere in the ODbL it says that. if you distribute a
produced work based on a derived database then you have to distribute
the derived database. it was suggested that, in addition to the named
methods of a) distributing a full dump or b) distributing a diff
between the derived and original, a third method be added which is
publishing the procedure.
this *doesn't* mean that anyone has to open their source code or their
secret procedures, just that they're limiting their options for
distributing derived databases to either full dumps or diffs. ODbL
might be a viral license, but it's only viral to data, never software.
