a) Change the title of Chapter 7 "Using UUIDs to Form OIDs" to "Using UUIDs as the Principal Integer Value of Joint UUID Arcs" and Unicode Tags", and modify the corresponding content of Chapter 7;

b) Deleted the original Chapter 16 "Registration of UUIDs and their use as OID components":

Introduction

GB/T 17969 is intended to specify the operating procedures of object identifier registration agencies: It is based on ISO/IEC 9834 and is intended to consist of five parts:

constitute:

--- Information technology Open Systems Interconnection (OSI) Registration Authority operating procedures Part 1: General procedures and international object identifiers the purpose of this standard is to define the international object identifier tree and its top-level arcs:

--- Information technology Open Systems Interconnection OSI Registration Authority operating procedures Part 3: Jointly managed by ISO and ITU-T Registration of object identifier arcs under the top-level arc (GB/T 17969.3-2008): The purpose is to specify the registration of the object identifier arc:

Record procedures, including revisions, additions, etc:

--- Information technology Open Systems Interconnection (OSI) Registration Authority operating procedures Part 5: Registration of VT control object definitions

Table (GB/T 17969.5-2000): The purpose is to specify the contents of the registration form:

--- Information technology Open Systems Interconnection (OSI) Registration Authority operating procedures Part 6: Application processes and application entities (GB/T 17969.6-2000): The purpose is to specify the registration procedures for application processes and application entities:

--- Information technology object identifier registration authority operating procedures Part 8: Generation and use of universal unique identifiers (UUIDs) its use in object identifiers:

Information Technology Object Identifier Registration Authority Operating Procedures Part 8: Universally Unique Identifiers (UUIDs) Generation of and use in object identifiers

1 Scope

This document specifies the format and generation rules for generating 128-bit identifiers that are guaranteed to be globally unique or have a high probability of being globally unique:

Ball only:

Follow this document to generate a new universally unique identifier (UUID) every 100ns for both temporary and permanent use:

Identifier:

This document is derived from, and is technically equivalent to, earlier non-standard specifications for UUIDs and their generation:

This document also specifies and allows the use of UUID as the primary value for each arc under the joint UUID arc (defined in Unicode):

This enables users to create and use such arcs without any registration procedure:

This document also specifies and enables the use of UUIDs to form Uniform Resource Names (URNs):
