          Inventory and Analysis of WHOIS Registration Objects

Abstract

   WHOIS output objects from registries, including both Regional
   Internet Registries (RIRs) and Domain Name Registries (DNRs), were
   collected and analyzed.  This document describes the process and
   results of the statistical analysis of existing WHOIS information.
   The purpose of this document is to build an object inventory to
   facilitate discussions of data objects included in Registration Data
   Access Protocol (RDAP) responses.
