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. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 9834-1:2008 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 6, Telecommunications and information exchange between systems, in collaboration with
ITU-T. The identical text is published as ITU-T Rec. X.660 (08/2008).
This third edition cancels and replaces the second edition (ISO/IEC 9834-1:2005), which has been technically
revised.
ISO/IEC 9834 consists of the following parts, under the general title Information technology — Open Systems
Interconnection — Procedures for the operation of OSI Registration Authorities:
⎯ Part 1: General procedures and top arcs of the International Object Identifier tree
⎯ Part 2: Registration procedures for OSI document types
⎯ Part 3: Registration of Object Identifier arcs beneath the top-level arc jointly administered by ISO and
ITU-T
⎯ Part 4: Register of VTE Profiles
⎯ Part 5: Register of VT Control Object Definitions
⎯ Part 6: Registration of application processes and application entities
⎯ Part 7: Joint ISO and ITU-T Registration of International Organizations
⎯ Part 8: Generation and registration of Universally Unique Identifiers (UUIDs) and their use as ASN.1

ISO/IEC 9834-1:2008 (E)
3.7 Additional definitions
3.7.1 additional secondary identifier: A secondary identifier for a top-level arc of the international object
identifier tree that is assigned from time to time by a simple Resolution of both the relevant ITU-T study group and the
relevant ISO/IEC JTC 1 Sub-Committee, without requiring any change to this or any other Recommendation and/or
International Standard (see A.6.4).
3.7.2 additional Unicode label: A Unicode label for one of the top-level arcs of the international object identifier
tree that is assigned from time to time by a simple Resolution of both the relevant ITU-T study group and the relevant
ISO/IEC JTC 1 Sub-Committee, without requiring any change to this or any other Recommendation | International
Standard (see A.6.4).
3.7.3 administrative role (of a Registration Authority): Assigning and making available unambiguous names
according to the Recommendation | International Standard defining the procedures for the Registration Authority (at
whatever depth).
3.7.4 integer-valued Unicode label: A Unicode label for an arc that is the character representation (with no leading
zeros) of the primary integer value of that arc.
NOTE – An arc of the international object identifier tree can have no other Unicode label that is the character representation
(with or without leading zeros) of an integer value (see 7.2.4).
3.7.5 International Registration Authority: A Registration Authority (see 3.7.17) acting at the international level
where the procedures for its operation, defined in a relevant Recommendation and/or International Standard, declare it
to operate as an International Registration Authority (see clause 8).
3.7.6 International Object Identifier tree: A specific form of an RH-name-tree whose root corresponds to this
Recommendation | International Standard and whose nodes correspond to registration authorities responsible for
allocating arcs from a parent node.
3.7.7 IRI/URI value: A value that identifies a resource using one of the schemes registered with IANA for URIs.
3.7.8 Joint ITU-T | ISO/IEC JTC 1 Collaborative Team for object identifiers: A group established in
accordance with ITU-T Rec. A.23, Annex A and ISO/IEC JTC 1 Directives Edition 5 Version 2.0, subclause 2.6.4 and
Annex K, clause 8 to progress work on Joint Text in relation to object identifiers (OIDs).
3.7.9 long arc: A Unicode label from a superior node in the international object identifier tree that identifies a node
that is not immediately beneath the superior node.
NOTE 1 – The long arc (in addition to normal arcs) has to satisfy the unambiguity requirements for all arcs from that superior
node (see 7.2.8).
NOTE 2 – The only property of a long arc (see 3.7.15) is its Unicode label. It does not have a primary integer value or a
secondary identifier. It is essentially a short-cut for a series of arcs, each of which has a primary integer value and its own
Unicode labels.
NOTE 3 – The long arc can therefore not be used to define the value of an (ASN.1) object identifier type. It can only be used in
an OID internationalized resource identifier (see 3.7.12).
3.7.10 object (of interest): Anything in some world, generally the world of telecommunications and information
processing or some part thereof,
a) which is identifiable (can be named); and
b) which may be registered.
NOTE – Examples of objects are ASN.1 modules (see ITU-T Rec. X.680 | ISO/IEC 8824-1), information objects (see ITU-T
Rec. X.681 | ISO/IEC 8824-2), managed objects (see ITU-T Rec. X.722 | ISO/IEC 10165-4), XML namespaces (see W3C XML
Namespaces) and any other object that can be identified by an OID, URI or IRI.
3.7.11 object identifier: An ordered list of primary integer values from the root of the international object identifier
tree to a node, which unambiguously identifies that node (see 7.2.8).
3.7.12 OID internationalized resource identifier: An IRI/URI value constrained to the IANA "oid" IRI/URI
scheme (see Annex F)
NOTE 1 – This is semantically an ordered list of Unicode labels, from the root of the international object identifier tree, that
unambiguously identifies the node for a resource (see 7.2.8)
NOTE 2 – The ASN.1 OID-IRI type (see ITU-T Rec. X.680 | ISO/IEC 8824-1) is the set of all OID international resource
identifier values, and provides value notations for all OID international resource identifiers based on the international object
identifier tree. Corresponding encodings are specified in the ITU-T Rec. X.690 series | ISO/IEC 8825 multipart Standard.
3.7.13 primary integer value: A primary value of type integer used to unambiguously identify an arc of the
international object identifier tree.
NOTE – An arc of the international object identifier tree has precisely one primary integer value, apart from long arcs, that have
only Unicode labels.
4 ITU-T Rec. X.660 (08/2008)
---------------------- Page: 9 ----------------------
ISO/IEC 9834-1:2008 (E)
3.7.14 primary value: A value of a specified type assigned to an arc of the RH-name-tree that can provide an
unambiguous identification of that arc within the set of arcs from its superior node.
3.7.15 properties of an arc: The primary integer value and the Unicode labels and secondary identifiers assigned to
that arc.
NOTE – Long arcs (see 3.7.9) have only Unicode labels. All other arcs have precisely one primary integer value.
3.7.16 registration: The assignment of an unambiguous name to an object in a way which makes the assignment
available to interested parties.
3.7.17 Registration Authority: An entity such as an organization, a standard or an automated facility that performs
registration of one or more types of objects (see also 3.7.5).
NOTE – For this Recommendation | International Standard, the above definition of registration authority extends the term to
cover registration by organizations acting at international, regional and national levels and by other means.
3.7.18 registration-hierarchical-name: A name which is unambiguous within the registration-hierarchical-
name-tree and which is assigned by registration. The semantic form of this name is structured according to the rules in
clause 6.
3.7.19 registration-hierarchical-name-tree: A tree whose nodes correspond to objects that are registered and
whose non-leaf nodes may be registration authorities.
3.7.20 registration procedures: The specified procedures for performing registration and amending (or deleting)
existing registrations.
3.7.21 relevant ITU-T study group: The ITU-T study group that is responsible for the Joint ITU-T | ISO/IEC JTC 1
Collaborative Team for object identifiers.
3.7.22 relevant ISO/IEC JTC 1 Sub-Committee: The ISO/IEC JTC 1 Sub-Committee that is responsible for the
Joint ITU-T | ISO/IEC JTC 1 Collaborative Team for object identifiers.
3.7.23 root arc: One of the three arcs from the root of the international object identifier tree.
3.7.24 secondary identifier: A secondary value restricted to the characters forming an (ASN.1) identifier (see
ITU-T Rec. X.680 | ISO/IEC 8824-1), assigned either in an ITU-T Recommendation, an International Standard or by
some other Registration Authority to an arc of the OID tree.
NOTE – An arc of the international object identifier tree can have zero or more secondary identifiers.
3.7.25 secondary value: A value of some type associated with an arc that provides additional identification useful
for human readers, but that does not in general unambiguously identify that arc, and is not normally included in
computer communications.
3.7.26 sponsoring authority: An organization recognized to receive proposals for registration and to submit
applications to an International Registration Authority as defined by a given Recommendation and/or International
Standard (see 8.2 and 8.3).
3.7.27 technical role (of a registration authority): Verifying that these definitions are in accordance with the
Recommendation and/or International Standard defining the form of the definition.
3.7.28 top-level arcs (top arcs): The subset of arcs of the international object identifier tree that are assigned
identifiers in this Recommendation | International Standard (supplemented by references to the ITU-T Rec. X.660 series
| ISO/IEC 9834 multipart Standards, or by a Resolution from time to time of both the relevant ITU-T study group and
the relevant ISO/IEC JTC 1 Sub-committee).
3.7.29 Unicode character: A character from the Unicode character set.
3.7.30 Unicode character set: The set of coded characters specified in ISO/IEC 10646.
NOTE – This is the same character set as that defined by the Unicode Consortium in [4].
3.7.31 Unicode label: A primary value that consists of an unbounded sequence of Unicode characters that does not
contain the SPACE character (see 7.2.5 for other restrictions) used to unambiguously identify an arc of the ASN.1 tree.
NOTE 1 – Unicode labels are always case sensitive for matching purposes and when determining unambiguity.
NOTE 2 – An arc of the international object identifier tree can have multiple Unicode labels.
NOTE 3 – Joint act

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. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 9834-1:2009 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 6, Telecommunications and information exchange between systems, in collaboration with
ITU-T. The identical text is published as ITU-T Rec. X.660 (08/2008).
This third edition cancels and replaces the second edition (ISO/IEC 9834-1:2005), which has been technically
revised.
ISO/IEC 9834 consists of the following parts, under the general title Information technology — Open Systems
Interconnection — Procedures for the operation of OSI Registration Authorities:
⎯ Part 1: General procedures and top arcs of the International Object Identifier tree
⎯ Part 2: Registration procedures for OSI document types
⎯ Part 3: Registration of Object Identifier arcs beneath the top-level arc jointly administered by ISO and
ITU-T
⎯ Part 4: Register of VTE Profiles
⎯ Part 5: Register of VT Control Object Definitions
⎯ Part 6: Registration of application processes and application entities
⎯ Part 7: Joint ISO and ITU-T Registration of International Organizations
⎯ Part 8: Generation and registration of Universally Unique Identifiers (UUIDs) and their use as ASN.1
Object Identifier components
⎯ Part 9: Registration of object identifier arcs for applications and services using tag-based identification

INTERNATIONAL STANDARD
ITU-T RECOMMENDATION
Information technology – Open Systems Interconnection – Procedures for
the operation of OSI Registration Authorities: General procedures
and top arcs of the International Object Identifier tree
1 Scope
This Recommendation | International Standard:
a) specifies a registration-hierarchical-name-tree (RH-name-tree) which is a generic tree structure for
allocations made by a hierarchical structure of Registration Authorities, and the specific form of this that
supports the ASN.1 OBJECT IDENTIFIER type and the ASN.1 OID-IRI type (see ITU-T Rec. X.680 |
ISO/IEC 8824-1);
b) registers top-level arcs of the international object identifier tree;
c) specifies procedures which are generally applicable to registration in the context of any RH-name-tree;
d) provides guidelines for the establishment and operation of International Registration Authorities for use,
when needed, by other Recommendations and/or International Standards;
e) provides guidelines for additional Recommendations | International Standards which choose to reference
the procedures in this Recommendation | International Standard;
f) provides a recommended fee structure for lower-level Registration Authorities;
g) records the information provided to IETF and the registration with IANA of the "oid" IRI scheme (see
Annex F).
NOTE 1 – This Recommendation | International Standard does not exclude or disallow the use of any syntactic form of names or
naming domains for registration purposes. This Recommendation | International Standard is intended to cover those cases where
a registration-hierarchical-name is an appropriate form of identification.
NOTE 2 – Information about registration for specific objects is contained in separate Recommendations | International Standards.
This Recommendation | International Standard applies to registration by Recommendations and/or International
Standards, by International Registration Authorities (see clause 8), and by any other Registration Authority.

3.7 Additional definitions
3.7.1 additional secondary identifier: A secondary identifier for a top-level arc of the international object
identifier tree that is assigned from time to time by a simple Resolution of both the relevant ITU-T study group and the
relevant ISO/IEC JTC 1 Sub-Committee, without requiring any change to this or any other Recommendation and/or
International Standard (see A.6.4).
3.7.2 additional Unicode label: A Unicode label for one of the top-level arcs of the international object identifier
tree that is assigned from time to time by a simple Resolution of both the relevant ITU-T study group and the relevant
ISO/IEC JTC 1 Sub-Committee, without requiring any change to this or any other Recommendation | International
Standard (see A.6.4).
3.7.3 administrative role (of a Registration Authority): Assigning and making available unambiguous names
according to the Recommendation | International Standard defining the procedures for the Registration Authority (at
whatever depth).
3.7.4 integer-valued Unicode label: A Unicode label for an arc that is the character representation (with no leading
zeros) of the primary integer value of that arc.
NOTE – An arc of the international object identifier tree can have no other Unicode label that is the character representation
(with or without leading zeros) of an integer value (see 7.2.4).
3.7.5 International Registration Authority: A Registration Authority (see 3.7.17) acting at the international level
where the procedures for its operation, defined in a relevant Recommendation and/or International Standard, declare it
to operate as an International Registration Authority (see clause 8).
3.7.6 International Object Identifier tree: A specific form of an RH-name-tree whose root corresponds to this
Recommendation | International Standard and whose nodes correspond to registration authorities responsible for
allocating arcs from a parent node.
3.7.7 IRI/URI value: A value that identifies a resource using one of the schemes registered with IANA for URIs.
3.7.8 Joint ITU-T | ISO/IEC JTC 1 Collaborative Team for object identifiers: A group established in
accordance with ITU-T Rec. A.23, Annex A and ISO/IEC JTC 1 Directives Edition 5 Version 2.0, subclause 2.6.4 and
Annex K, clause 8 to progress work on Joint Text in relation to object identifiers (OIDs).
3.7.9 long arc: A Unicode label from a superior node in the international object identifier tree that identifies a node
that is not immediately beneath the superior node.
NOTE 1 – The long arc (in addition to normal arcs) has to satisfy the unambiguity requirements for all arcs from that superior
node (see 7.2.8).
NOTE 2 – The only property of a long arc (see 3.7.15) is its Unicode label. It does not have a primary integer value or a
secondary identifier. It is essentially a short-cut for a series of arcs, each of which has a primary integer value and its own
Unicode labels.
NOTE 3 – The long arc can therefore not be used to define the value of an (ASN.1) object identifier type. It can only be used in
an OID internationalized resource identifier (see 3.7.12).
3.7.10 object (of interest): Anything in some world, generally the world of telecommunications and information
processing or some part thereof,
a) which is identifiable (can be named); and
b) which may be registered.
NOTE – Examples of objects are ASN.1 modules (see ITU-T Rec. X.680 | ISO/IEC 8824-1), information objects (see ITU-T
Rec. X.681 | ISO/IEC 8824-2), managed objects (see ITU-T Rec. X.722 | ISO/IEC 10165-4), XML namespaces (see W3C XML
Namespaces) and any other object that can be identified by an OID, URI or IRI.
3.7.11 object identifier: An ordered list of primary integer values from the root of the international object identifier
tree to a node, which unambiguously identifies that node (see 7.2.8).
3.7.12 OID internationalized resource identifier: An IRI/URI value constrained to the IANA "oid" IRI/URI
scheme (see Annex F)
NOTE 1 – This is semantically an ordered list of Unicode labels, from the root of the international object identifier tree, that
unambiguously identifies the node for a resource (see 7.2.8)
NOTE 2 – The ASN.1 OID-IRI type (see ITU-T Rec. X.680 | ISO/IEC 8824-1) is the set of all OID international resource
identifier values, and provides value notations for all OID international resource identifiers based on the international object
identifier tree. Corresponding encodings are specified in the ITU-T Rec. X.690 series | ISO/IEC 8825 multipart Standard.
3.7.13 primary integer value: A primary value of type integer used to unambiguously identify an arc of the
international object identifier tree.
NOTE – An arc of the international object identifier tree has precisely one primary integer value, apart from long arcs, that have
only Unicode labels.
4 ITU-T Rec. X.660 (08/2008)
---------------------- Page: 9 ----------------------
ISO/IEC 9834-1:2008 (E)
3.7.14 primary value: A value of a specified type assigned to an arc of the RH-name-tree that can provide an
unambiguous identification of that arc within the set of arcs from its superior node.
3.7.15 properties of an arc: The primary integer value and the Unicode labels and secondary identifiers assigned to
that arc.
NOTE – Long arcs (see 3.7.9) have only Unicode labels. All other arcs have precisely one primary integer value.
3.7.16 registration: The assignment of an unambiguous name to an object in a way which makes the assignment
available to interested parties.
3.7.17 Registration Authority: An entity such as an organization, a standard or an automated facility that performs
registration of one or more types of objects (see also 3.7.5).
NOTE – For this Recommendation | International Standard, the above definition of registration authority extends the term to
cover registration by organizations acting at international, regional and national levels and by other means.
3.7.18 registration-hierarchical-name: A name which is unambiguous within the registration-hierarchical-
name-tree and which is assigned by registration. The semantic form of this name is structured according to the rules in
clause 6.
3.7.19 registration-hierarchical-name-tree: A tree whose nodes correspond to objects that are registered and
whose non-leaf nodes may be registration authorities.
3.7.20 registration procedures: The specified procedures for performing registration and amending (or deleting)
existing registrations.
3.7.21 relevant ITU-T study group: The ITU-T study group that is responsible for the Joint ITU-T | ISO/IEC JTC 1
Collaborative Team for object identifiers.
3.7.22 relevant ISO/IEC JTC 1 Sub-Committee: The ISO/IEC JTC 1 Sub-Committee that is responsible for the
Joint ITU-T | ISO/IEC JTC 1 Collaborative Team for object identifiers.
3.7.23 root arc: One of the three arcs from the root of the international object identifier tree.
3.7.24 secondary identifier: A secondary value restricted to the characters forming an (ASN.1) identifier (see
ITU-T Rec. X.680 | ISO/IEC 8824-1), assigned either in an ITU-T Recommendation, an International Standard or by
some other Registration Authority to an arc of the OID tree.
NOTE – An arc of the international object identifier tree can have zero or more secondary identifiers.
3.7.25 secondary value: A value of some type associated with an arc that provides additional identification useful
for human readers, but that does not in general unambiguously identify that arc, and is not normally included in
computer communications.
3.7.26 sponsoring authority: An organization recognized to receive proposals for registration and to submit
applications to an International Registration Authority as defined by a given Recommendation and/or International
Standard (see 8.2 and 8.3).
3.7.27 technical role (of a registration authority): Verifying that these definitions are in accordance with the
Recommendation and/or International Standard defining the form of the definition.
3.7.28 top-level arcs (top arcs): The subset of arcs of the international object identifier tree that are assigned
identifiers in this Recommendation | International Standard (supplemented by references to the ITU-T Rec. X.660 series
| ISO/IEC 9834 multipart Standards, or by a Resolution from time to time of both the relevant ITU-T study group and
the relevant ISO/IEC JTC 1 Sub-committee).
3.7.29 Unicode character: A character from the Unicode character set.
3.7.30 Unicode character set: The set of coded characters specified in ISO/IEC 10646.
NOTE – This is the same character set as that defined by the Unicode Consortium in [4].
3.7.31 Unicode label: A primary value that consists of an unbounded sequence of Unicode characters that does not
contain the SPACE character (see 7.2.5 for other restrictions) used to unambiguously identify an arc of the ASN.1 tree.
NOTE 1 – Unicode labels are always case sensitive for matching purposes and when determining unambiguity.
NOTE 2 – An arc of the international object identifier tree can have multiple Unicode labels.
NOTE 3 – Joint act
