二级域标签生成规则 (LGR) 参考文件提案征询

互联网名称与数字地址分配机构 (ICANN) 现正按照新机读正式表述方式,征召多语言(文字)二级域标签生成规则 (LGR) 提供商,该表述方式请参见:

在新通用顶级域项目的授权前测试阶段 (PDT),ICANN 注意到有大量的 IDN 列表提交。新通用顶级域注册管理机构提交的 IDN 列表在字汇和语境规则上均有所不同。为了改善注册管理机构在运营新通用顶级域时的测试一致性和稳定性,ICANN 批准了在授权前测试阶段 (PDT) 和注册管理机构服务评估流程 (RSEP) 中编制可用的二级域 LGR 参考文件。这些列表将按照权威资料进行编制,由专家核实,并在处理了社群反馈意见后最终定稿。一旦定稿,这些列表将由 ICANN 公开发布。

ICANN 有意将这类二级域 LGR 参考文件用于内部运营,并面向社群公开发布。

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"""" is not an IDN."
