Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations,
governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/
IEC Directives, Part 2 (see www.iso.org/directives or www.iec.ch/members_experts/refdocs).
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any
claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not
received notice of (a) patent(s) which may be required to implement this document. However, implementers
are cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not be held
responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www.iso.org/iso/foreword.html.

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 6, Telecommunications and information exchange between systems.
This second edition cancels and replaces the first edition (ISO/IEC 29168-2:2011), which has been technically
revised.
The main changes are as follows:
— a secondary operational agency has been introduced as a complement to the primary operational agency,
along with rules for its appointment;
— requirements for the nominees for the primary operational agency have been added;
— requirements for accessing an up-to-date OID root zone file have been added.
A list of all parts in the ISO/IEC 29168 series can be found on the ISO and IEC websites.

body. A complete listing of these bodies can be found at www.iso.org/members.html and

Introduction
An introduction to the object identifier (OID) resolution system is provided in ISO/IEC 29168-1.
This document specifies the mechanisms and criteria to be applied for the selection and approval of the
object identifier resolution system (ORS) operational agency. It also covers the procedures that the ORS
operational agency is required to follow when managing the ORS.
The domain name system (DNS) zone files for .oid-res.org must provide ORS support for the root of the
International Object Identifier tree.
These procedures include the appointment (or re-appointment) of the ORS operational agency (the
operational agency).
The procedures require the operational agency to provide DNS zone file support for .oid-res.org, as well as
for a specified set (see Clause 6) of top-level OID nodes, including domain name system security extension
(DNSSEC) (NSEC3) support for those zone files.
The operational agency is also required to support specified procedures (some, but not all, on a commercial
basis) that enable the provision of ORS support for OID nodes beneath those that it is fully required to
support (see Table 1).
Clause 5 specifies the approval mechanisms for the appointment of the operational agency and any necessary
subsequent changes.
Clause 6 specifies the OID nodes to be supported by the operational agency.
Clause 7 specifies the nature of operational agency support.
Clause 8 addresses charging issues for services provided by the operational agency.

This document specifies the mechanisms and criteria to be applied for the selection and approval of the
