8、RD ISO/IEC 9834-1 ITU-T RECOMMENDATION X.660 Information technology Open Systems Interconnection Procedures for the operation of OSI Registration Authorities: General procedures and top arcs of the International Object Identifier tree Summary ITU-T Recommendation X.660 | ISO/IEC 9834-1 defines a gen

9、eric registration-hierarchical-name-tree (RH-name-tree) and a specific form of this RH-name-tree that supports international object identifiers (OIDs). It includes registration of the top-level arcs of the OID tree. It also specifies procedures for the operation of an International Registration Auth

10、ority for use, when needed, by other Recommendations and/or International Standards. For easy reference, and to emphasize that this tree is an extended form of the original OID tree (defined in earlier versions of this Recommendation | International Standard), this specific RH-name-tree can be refer

11、red to as “the international OID tree“, or more commonly as just “the OID tree“. The OID tree (defined as the International Object Identifier Tree) specified in this edition is a superset of the original OID tree, which did not support Unicode labels (names of arcs in any language, using the Unicode

12、 character set). The original OID tree required all arcs to be unambiguously identified by a primary integer value, with the use for human readability of (not necessarily unambiguous) secondary identifiers (restricted to the Latin alphabet). Secondary identifiers were not normally carried in protoco

13、ls or used for machine identification. The International Object Identifier tree extends this by allowing an arc to also be unambiguously identified by a Unicode label (a string of Unicode characters) that can be carried in protocols and can be used for machine identification. The primary integers an

14、d secondary identifiers of the International Object Identifier tree continue to be used in encoding (primary integers only) and value notation (primary integers and secondary identifiers) of the ASN.1 OBJECT IDENTIFIER type, which is unchanged. The Unicode labels can only be used in encodings and va

15、lue notation of the ASN.1 OID-IRI type, and in the specification of an IRI or URI (see IETF RFC 3987). It also provides recommendations on an appropriate fee structure for registration of lower level arcs (see clause 11). Source ITU-T Recommendation X.660 was approved on 29 August 2008 by ITU-T Stud

16、y Group 17 (2005-2008) under the ITU-T Recommendation A.8 procedure. An identical text is also published as ISO/IEC 9834-1. ii ITU-T Rec. X.660 (08/2008) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information

17、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 standardizing telecommunications on a worldwide

18、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 by the procedure laid down in WTSA Re

19、solution 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 both a telecommunication administrati

20、on 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 all of these mandatory provisions a

21、re 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 RIGHTS ITU draws attention to the p

22、ossibility 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 ITU members or others outside of t

23、he 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. However, implementers are cautioned that this may not represent the latest inf

24、ormation and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2009 All rights reserved.

34、n 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 hierarchi

35、cal 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 gener

36、ally 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 Recommendation

37、s | 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 (

38、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.
