Registration Data Access Protocol (RDAP) Query Parameters for Result
Sorting and Paging
draft-ietf-regext-rdap-sorting-and-paging-06
Abstract
The Registration Data Access Protocol (RDAP) does not include core
functionality for clients to provide sorting and paging parameters
for control of large result sets. This omission can lead to
unpredictable server processing of queries and client processing of
responses. This unpredictability can be greatly reduced if clients
can provide servers with their preferences for managing large
responses. This document describes RDAP query extensions that allow
clients to specify their preferences for sorting and paging result
sets.

1. Introduction
The availability of functionality for result sorting and paging
provides benefits to both clients and servers in the implementation
of RESTful services [REST]. These benefits include:
o reducing the server response bandwidth requirements;
o improving server response time;
o improving query precision and, consequently, obtaining more
reliable results;
o decreasing server query processing load;
o reducing client response processing time.
