Raw Blame History

Introduction
------------
Handlers are pieces of code that parse the raw whois output and try
to add some keys to the result returned by phpWhois. In previous
versions there was no standard about how these keys should be named
and organized, which make them registry specific. Now all handlers
have been standarized so they return a known set of keys. This is what
we call 'Common Object Model'.
Common Object Model
-------------------
The keys that you could find in the result array returned by phpWhois
are 'rawdata' , 'regyinfo' and 'regrinfo'.
rawdata is always returned as it's filled by phpWhois itself. It
contains the raw text output returned by the whois server.
regyinfo contains information about the registry who returned that
information. It has four subkeys: 'servers' which is an array with
one entry for each whois server who returned the data, 'referrer' the
web address of the registry, 'registar' the company name of the registry
and 'type' which can be 'domain', 'ip' or 'AS'. The 'servers' array
has subkeys 'server' the whois server, 'port' the whois server port and
'args' the query sent to the server.
regrinfo holds the information about the domain itself. It could have
the following subkeys:
disclaimer
----------
Contains the disclaimer returned by the registry.
registered
----------
Contains Yes or No and indicates if the domain or ip
address has been found (it exists).
domain
------
Only when dealing with domains. Could contain the
following subkeys:
name -> domain name
desc -> description of the domain
nserver -> array where the key is the canonical name
of each nameserver and the value is the
ip adresss (if none) of the server.
status -> status of the domain (registry dependant)
changed -> date of last change
created -> creation date
expires -> expire date
sponsor -> registry partner where the domain was
registered
referer -> sponsor's URL
handle -> domain handle
source -> who gives this information
network
-------
Only when dealing with ip addresses. Could contain the
following subkeys:
name -> network/AS name
inetnum -> network ip address range
desc -> network description
mnt-by -> who provided that network
mnt-lower> who provided that network
nserver -> name servers in listed order that
provide inverse resolution for that net
status -> status of the network (registry dependant)
remarks -> remarks provided by the registry
changed -> date of last change
created -> creation date
handle -> network/AS handle
source -> who gives this information
AS
--
Only when dealing with Autonomus systems, could contain
the same subkeys as network.
owner,admin,tech,zone,billing,abuse
-----------------------------------
All of these possible keys hold information about the different
contacts of the domain or ip address. They all could have the
same subkeys, that are:
organization -> organization name
name -> organization responsible
type -> type of contact
address -> array containing the address, the
keys of that array could be just
numbers, could have predefined
subkeys or could be amix of numbers
and predefined subkeys. Predefined
subkeys are street, city,
state, pcode and country
phone -> phone, could also be an array of
phone numers
fax -> fax, same behaviour as phone
email -> email, same behaviour as phone
handle -> contact handle
mnt-by -> who provided that contact
created -> creation date
changed -> last change date
source -> who provided that information
remarks -> remarks
When information is requested on ip addresses any of those
keys could be an array which will contain all data found on
different whois or rwhois servers (each owner, admin, tech,
etc ... found in each query).
Not all handlers fill values in each of the keys defined by the
Common Object Model as not all registries return the same amount
of data about a domain or ip address. Also there are some differences
on the format returned for some keys.
Dates (created/changed/expires) are always returned in the format
yyyy-mm-dd when a handler is defined for the returned data.
Writing handlers
----------------
Writing handlers is easy, just look at how some of them are coded.
If you write a new handler, please try to map as many as possible
returned data to keys defined by the 'Common Object Model'. You can
create new keys if need, but please do not do create new keys where
existing predefined keys exists. Nevertheless all handlers submited
will be checked before they are added to phpWhois distribution.
If some tld needs special parameters or can be queried in
another whois servers or web base whois servers you can setup
rules in whois.servers.php so phpWhois can do the right thing.
There is also a naming schema that must be followed, country
handlers are named whois.XX.php, where XX is the iso country
code. The handler must also define __XX_HANDLER__ and implement
a class named xx_handler with a function named parse that takes
two arguments: $data_str and $query. $data_str['rawdata']
contains the raw output of the query and is what need to be parsed
in order to generate the Common Object Model. $query contains
the domain, ip adrress or AS that it's being queried. That function
must return an array with any available result in the format defined
by this document. Country handlers need not to be defined in
the file whois.servers.php, only when you want to use some handler
for several different country domains you need to add it to the array
DATA where the key is the iso country code and the value the handler
name (xx).
Handlers for .com/.net/.tv domains are handled by whois.gtld.php
and named whois.gtld.xxx.php where xxx is the 'midname' (for example,
for whois.srsplus.com, the midname is srsplus) of the whois server who
provides information for that domains. If you want to reuse another
handler of your handler 'midname' conflicts with any existing gtld
handler you could define the handler name in the array WHOIS_GTLD_HANDLER
in the file whois.servers.php. It must be implemented the same way as
country handlers.
Some useful utility functions have been written to aid in developing
handlers. They are contained in whois.parser.php. Almost all handlers
use functions provided by that file. You can see how they work by
looking into the code. You also have a handler.template.php file
with the squeleton of a handler.
Please try to mimic the coding style of the other handlers, as this
will make it easier for other people to understand and maintain.
Some support functions have been developed to help you write new
handlers, those functions are stored on the following files:
- generic_parser_a:
contains code to parse whois outputs in RPSL format, like this one.
