1. Introduction
This document defines the policies and procedures for inserting
Naming Authority Pointer (NAPTR) records into the 'URI.ARPA' and
'URN.ARPA' zones for the purpose of resolving Uniform Resource
Identifiers (URIs) according to "Dynamic Delegation Discovery System
(DDDS) Part Four: The URI Resolution Application" (RFC 3402) [2],
which is an Application that uses the Domain Name System (DNS) based
DDDS Database. All of these concepts are defined in RFC 3401 [1].
It is very important to note that it is impossible to correctly
understand this document without reading RFC 3401 and the documents
it specifies.
RFC 3403 defines a how DNS is used as a DDDS database that contains
URI delegation rules (sometimes called resolution hints). That
document specifies that the first step in that algorithm is to append
'URI.ARPA' to the URI scheme and retrieve the NAPTR record for that
domain-name. I.e., the first step in resolving "http://foo.com/"
would be to look up a NAPTR record for the domain "http.URI.ARPA".
URN resolution also follows a similar procedure but uses the
'URN.ARPA' zone as its root. This document describes the procedures
for inserting a new rule into the 'URI.ARPA' and 'URN.ARPA' zones.
2. URI Resolution vs URN Resolution
RFC 3402 [2] defines how both URI [7] resolution and URN [6]
resolution work when DNS is used as the delegation rule (or hint)
database. Specifically it says that the initial instructions
('hints') for DNS-based resolution of URIs are stored as resource
records in the 'URI.ARPA' DNS zone.
Since a URN is a URI scheme, a hint for resolution of the URI prefix
