about ripe.db on ftp.ripe.net

Hi,
I'm doing a statistic work on ripe.db for my University (Faculty of 
Science of the Lisbon University)
and I downloaded ripe.db.inetnum (from the split files directory) so I 
can do statistics on several
portuguese speaking countrys and Portugal itself. The ripe.db.inetnum 
suits my needs exactly but
the admin-c: and tech-c: objects refer to person: objects which can't be 
found on ripe.db.
I've googled a bit and found reference (back in 1993) of a split of 
ripe.db named ripe.db.person
which probably had the additional information I need.
Since I don't see that ripe.db.person anywhere on the ftp and the other 
.db files don't have person:
objects, I was wondering if they were removed due to spam issues or 
something, since they're accessible through normal whois.ripe.net 
query's (which are bound to massive querying limits).
Could someone shed some light into this matter?

regards,
Francisco Guerreiro
