Parser doesn't seem to return correct value for created_on

[tonypersona]

Here are examples I ran in my Ruby console.

1. You'll see a "Creation Date: 2002-06-21T14:22:15Z" key in the WHOIS record, but it's not populating correctly

[39] dev@us-central1 (main)> whois.lookup('uct.ac.za').parser.created_on
Whois::AttributeNotImplemented: Unable to find a parser for property `created_on'
from /usr/local/bundle/gems/whois-parser-2.0.0/lib/whois/parser.rb:365:in `delegate_property_to_parsers'
[40] dev@us-central1 (main)> whois.lookup('uct.ac.za').parser
#<Whois::Parser:0x0000ffff6c6b9ab0 @record="Whois Server: whois.ac.za\r\nReferral URL: https://whois.ac.za/\r\nDomain Name: uct.ac.za\r\nRegistry Domain ID: dom_1OC3--1\r\nUpdated Date: 2024-07-01T00:00:07Z\r\nCreation Date: 2002-06-21T14:22:15Z\r\nRegistry Expiry Date: 2025-07-01T00:00:00Z\r\nRegis...

2. This is for NL

[46] dev@us-central1 (main)> a=Whois.lookup('careless-nederland.nl')
"Domain name: careless-nederland.nl\r\nStatus:      active\r\n\r\nRegistrar:\r\n   IONOS SE\r\n   Elgendorfer Strasse 57\r\n   56410 Montabaur\r\n   Germany\r\n\r\nAbuse Contact:\r\n   abuse@ionos.com\r\n\r\nDNSSEC:      no\r\n\r\nDomain nameservers:\r\n   ns1020.ui-dns.com\r\n   ns1032.ui-dns.org\r\n   ns1087.ui-dns.biz\r\n   ns1063.ui-dns.de\r\n\r\nCreation Date: 2017-12-09\r\n\r\nUpdated Date: 2022-02-18\r\n\r\nRecord maintained by: SIDN BV\r\n"
[47] dev@us-central1 (main)> a.parser.created_on
nil

Could you point me in the right direction on how to get the Creation Date to return correctly?

Those attributes do not seem to be supported/implemented in the specific parser for these TLDs. You can write a PR to add support for them (or see if there's another better parser to re-use for these TLDs). The main repository here has been abandoned though, so if you do contribute, you may want to submit your PR on my fork which is much more up-to-date: https://github.com/jarthod/whois-parser.

Also for some TLD like .NL you can use RDAP (ruby gem) instead of WHOIS, which uses a structured json API common to all TLDs so it's much more reliable to get such information. But unfortunately not all TLD has an RDAP server yet (.ac.za does not for example).

 {"eventAction"=>"last update of RDAP database", "eventDate"=>"2024-09-07T22:10:34Z"}]
