9、-T Recommendation X.662 | ISO/IEC 9834-3 specifies the procedures for operating the International Registration Authority for assignment of values to object identifier arcs beneath the top-level arc with primary integer value 2, Unicode label Joint-ISO-ITU-T and secondary identifier joint-iso-itu-t.
10、Assignment of the authority to allocate arcs beneath such arcs is either given to a specific area of work approved jointly by ISO/IEC and ITU-T (and is normally recorded in Recommendations | International Standards) or is given to an international organization. Source ITU-T Recommendation X.662 was
11、approved on 29 August 2008 by ITU-T Study Group 17 (2005-2008) under ITU-T Recommendation A.8 procedure. An identical text is also published as ISO/IEC 9834-3. ii ITU-T Rec. X.662 (08/2008) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field
12、 of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizin
13、g telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered b
14、y the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate b
15、oth a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when
16、all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY
17、RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by
18、 ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation.

X.660 | ISO/IEC 9834-1 defines procedures for registration to meet requirements for assignment of unambiguous names to o
23、bjects. These registration procedures are generally applicable to registration independent of the type of object involved. In particular, ITU-T Rec. X.660 | ISO/IEC 9834-1 defines the International Object Identifier tree, which is a tree whose nodes correspond to objects that are registered and whos
24、e non-leaf nodes may be Registration Authorities. ITU-T Rec. X.660 | ISO/IEC 9834-1 also defines procedures for the delegation of authority for the assignment of names in order to ensure that names are unambiguous. The International Object Identifier tree supports the ASN.1 object identifier and OID
25、 internationalized resource identifier types. The root of the International Object Identifier tree is ITU-T Rec. X.660 | ISO/IEC 9834-1. There are three root arcs from this root: Primary integer value Resulting integer-valued Unicode label (Non-integer) Unicode label Secondary identifier 0 “0“ “ITU-
26、T“ itu-t 1 “1“ “ISO“ iso 2 “2“ “Joint-ISO-ITU-T“ joint-iso-itu-t The Registration Authority for the nodes identified by the top-level arcs with primary integer values 0 and 1 (Unicode labels “ITU-T“ and “ISO“) are provided by ITU-T Rec. X.660 | ISO/IEC 9834-1, Annex A. Further discussion is beyond t
27、he scope of this Recommendation | International Standard. The operation of the Registration Authority for the node identified by the joint arc (see 3.3) is specified in this Recommendation | International Standard. The corresponding register is called the “Register of arcs beneath the top arc with p
28、rimary integer value 2“. ISO/IEC 9834-3:2008 (E) ITU-T Rec.

38、| International Standard, the following abbreviations apply: ASN.1 Abstract Syntax Notation One OID Object Identifier 5 General information 5.1 When a new arc is allocated beneath the joint arc, it identifies an international organization or an area of joint work between ITU-T and ISO. 5.2 Where an
39、allocation is made to an international organization or to an area of joint work, the responsible officers shall ensure that an appropriate tree of Registration Authorities be established in order to record all subsequent allocations. 5.3 The allocation determines the primary integer value and option
40、ally one or more Unicode labels and secondary identifiers for the new arc. 5.4 The allocation may also add a new long arc from the root to directly identify the new node in accordance with ITU-T Rec. X.660 | ISO 9834-1, A.6. It may also add additional secondary identifiers or additional Unicode labe
41、ls to the joint arc in accordance with ITU-T Rec. X.660 | ISO 9834-1, A.7. NOTE The provision for additional secondary identifiers or additional Unicode labels on the root nodes pre-dated the provision for long arcs. The long arc mechanism would normally be preferred. 6 Elements of information of a
42、register entry 6.1 The elements of information of a register entry shall be: a) the identification of a new node (Registration Authority) in the International Object Identifier tree by assigning a primary value and names to a new arc beneath the joint arc; the names shall consist of: 1) an integer-v
43、alued Unicode label (defined by the primary integer value) and; 2) (optionally) one or more non-integer Unicode labels; and 3) (optionally) one or more secondary identifiers; b) either: 1) an area of joint ISO/IEC and ITU-T work which will be the Registration Authority responsible for the allocation
44、 of a sub-tree beneath the arc specified in a) above, specified by the ISO project number and the number of the International Standard in which the sub-tree arcs will be specified, and the ITU-T Study Group, Study Period, and Question, and the number of the ITU-T (or CCITT) Recommendation in which t
45、he sub-tree arcs will be specified, and a brief title; or ISO/IEC 9834-3:2008 (E) ITU-T Rec. X.662 (08/2008) 3 2) an international organization which will be the Registration Authority responsible for the allocation of a sub-tree beneath the arc specified in a) above; EXAMPLE The Universal Postal Un
46、ion (UPU) or the Organization for Advancing Open Standards for the Information Society (OASIS) are examples of such international organizations. c) status of the entry indicating whether the entry is “active“ or “deleted“; and d) either: 1) a “Responsible Officer“ nominated by ISO/IEC and a “Respons
47、ible Officer“ nominated by ITU-T, who will jointly agree on the assignment of sub-tree arcs within the area of work; or 2) a “Responsible Officer“ in the international organization that is responsible for the assignment of sub-tree arcs for that organization. 6.2 The registration entry for an arc fr
48、om the joint arc shall be identified by specifying that it is the entry for an arc from the joint arc and by giving its primary integer value. An alternative form of identification would be by the use of an IRI/URI value (see ITU-T Rec. X.660 | ISO/IEC 9834-1, Annex F), with either two Unicode label
49、s or a single Unicode label for the long arc (if one has been allocated). 7 Procedures 7.1 Maintenance of the register The “Register of arcs beneath the root arc with primary integer value 2“ is to be maintained in accordance with ITU-T Rec. X.660 | ISO/IEC 9834-1, A.8.1.4, recording for each entry the information required by clause 6, using the proforma in Annex A or otherwise. NOTE It is recommended that the Register be made publicly available through the OID repository at http:/www.oid- 7.2 Recording of
