发布通知:《IDN ccTLD 快速通道流程实施计划》修订版

本页面还提供其他语种:

继 ICANN 理事会 2011 年 12 月 8 日通过《IDN ccTLD快速通道流程实施计划》的修订工作之后,ICANN 现发出有关《实施计划》修订版的发布通知。本次修订工作是在遵照 ICANN 塞纳加尔达喀尔会议期间从 ccNSO 收到的相关指导意见的基础上考虑进行的。

本次发布两个版本:1) 《IDN ccTLD快速通道流程实施计划》修订版

(http://www.icann.org/en/topics/idn/fast-track/idn-cctld-implementation-plan-15dec11-en.pdf [PDF, 851 KB]) 和 2) 带有修订标记的上一版本 (http://www.icann.org/en/topics/idn/fast-track/idn-cctld-implementation-plan-redline-15dec11-en.pdf [PDF, 902 KB])。ICANN 机构群体应注意,原来的《IDN ccTLD 快速通道流程实施计划》现已存档,代而使用《实施计划》修订版。

背景信息

2011 年 10 月 26 日,ccNSO委员会通过决议,并由ccNSO主席通过信函知会 ICANN 理事会主席,要求理事会指示 ICANN 工作人员修改《IDNccTLD快速通道实施计划》的相关章节。在 IDN ccTLD字符串申请中,所申请的 IDN ccTLD字符串与对应相同国家或地区的双字母 ASCII ccTLD在拼写形式上可能存在相似的情况,容易引起混淆,此次修订即是针对这一特殊情况来修改实施计划。

该项工作缘起于 2011 年 3 月 ICANN 旧金山会议上的ccNSO 委员会决议。此项决议要求 IDN ccPDP 第 1 工作组的下属小组(在快速通道现有规则框架内)尽快形成指导意见,以提高由《IDNC 工作组最终报告》和《最终实施计划》规定并由 ICANN 理事会在 2009 年 11 月采纳的与字符串混淆有关的评估流程的可预测性。

ICANN 在 2010 年 10 月至 2011 年 1 月期间对 IDN ccTLD快速通道流程及其实施情况做了初步审查,在 2011 年 2 月发布了总结与分析报告,在 3 月的 ICANN 会议上,理事会对快速通道流程的审查工作表示认可

2009 年 10 月的韩国首尔会议上,ICANN 理事会正式通过了《IDNccTLD快速通道流程实施计划》。原始《实施计划》的访问链接如下:http://www.icann.org/en/topics/idn/fast-track/idn-cctld-implementation-plan-16nov09-en.pdf [PDF, 498 KB]

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as""icann.org"" is not an IDN."
