WHOIS Data Extracted From Templates (deft-whois)
I now have a properly packaged Perl version of my "whois" processing system (Net::Whois::DeftWhois) and it is currently being alpha-tested.
The basic idea is that the whois data is processed against a registrar specific template to pick out the various parts of the data as accurately as possible. There is a big emphasis on correctly picking out phone numbers and identifying privacy and proxy services (because that is what our ICANN project was all about).
At present, coverage of country TLDs is limited, but there is pretty good coverage for com/net/org/info/biz.
