第二版根区标签生成规则 (RZ-LGR-2) 纳入六种文字

互联网名称与数字地址分配机构 (The Internet Corporation for Assigned Names and Numbers, ICANN) 今日针对第二版根区标签生成规则 (Root Zone Label Generation Rules, RZ-LGR-2) 启动公共评议期,该规则目前已经纳入了以下六种文字:阿拉伯文、埃塞俄比亚语、格鲁吉亚文、高棉语、老挝语和泰国语。

根区标签生成规则 (Label Generation Rules, LGR) 将被用于确定有效的顶级国际化域名 (Internationalized Domain Name, IDN) 标签及其变体标签(若有)。以社群为基础的生成专家组们 (Generation Panels) 正在编制其他文字的提案,使得这些提案能够被纳入根区 LGR 的后续版本。这包括中文、西里尔文、希腊文、日文、韩文、拉丁文和新婆罗米文专家组。

希伯来文、缅甸文、僧伽罗文、藏文和塔安那文的生成专家组正在根据《生成专家组征询 (Call for Generation Panels)》进行召集。现鼓励对这些文字经验丰富或感兴趣的人员积极参加这项志愿工作,帮助构建一个多语言的互联网。

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."
