Overview

Parses an RDAP domain object (RFC 9083).

RDAP is where structured data was the point, so this parser reads fields instead of guessing at prose. Two parts of the format still need translating: dates live in an events array keyed by eventAction rather than in named fields, and contacts are jCard/vCard arrays (RFC 7095) — a nested array of [name, params, type, value] tuples that has to be walked to find an email.

Constant Summary collapse

EVENTS =

eventAction values mapped to the record fields they populate.

{
  "registration" => :created_on,
  "last changed" => :updated_on,
  "last update of rdap database" => nil, # about the database, not the domain
  "expiration" => :expires_on
}.freeze
ROLES = 
{
  "registrant" => :registrant,
  "administrative" => :admin,
  "technical" => :tech,
  "billing" => :billing,
  "registrar" => :registrar
}.freeze
VCARD_FIELDS =

jCard property name => the record field it populates. adr is absent because its value is a structured array rather than a plain string.

{ "fn" => :fn, "org" => :org, "email" => :email, "tel" => :tel }.freeze
