Table of Contents

1. Introduction

Part five of the Dynamic Delegation Discovery System (DDDS), RFC 3405 [RFC3405], describes the registration procedures for assignments in URI.ARPA. The document requires that registrations be in the "IETF tree" of URI registrations. The use of URI scheme name trees was defined in RFC 2717 [RFC2717] but discontinued by RFC 4395 [RFC4395]. Since the use of trees was discontinued, there is no way in the current process set out in BCP 35 [RFC7595] to meet the requirement.

1.1. Requirements Language

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119][RFC8174] when, and only when, they appear in all capitals, as shown here.

2. Updated Requirements

This document removes the normative requirement from RFC 3405 for registrations in URI.ARPA to be from the IETF URI Tree.

All registrations in URI.ARPA MUST now be for schemes which are permanent registrations, as they are described in BCP 35.
