负责阿拉伯文根区域标签生成规则的生成专家组就职

ICANN 非常高兴地宣布,负责阿拉伯文根区域标签生成规则 (LGR) 的生成专家组已经正式 就职。

继 2013 年 7 月 11 日发布负责制定根区域标签生成规则的生成专家组招募书之后,由中东战略工作组 (MESWG) 倡议、机构群体促成的阿拉伯文国际化域名任务组 (TF-AIDN) 编制了一份负责阿拉伯文根区域标签生成规则集的生成专家组的提案 [PDF, 772 KB](LGR 程序),并于 2014 年 1 月 13 日送呈 ICANN。为确保符合 LGR 程序 [PDF, 772 KB] 中的规定,特别是符合负责制定根区域标签生成规则的生成专家组招募书中的标准,ICANN 在审核提案时充分考虑了专家组的成员组成和活动范围。

借此机会,ICANN 还想对每一位成员表示感谢,谢谢他们为阿拉伯文生成专家组付出的时间和提供的专业知识。

在相关文档和工作计划获得通过后,阿拉伯文生成专家组便开始着手制定标签生成规则。根据 LGR 程序 [PDF, 772 KB] 的规定,任何生成专家组的工作都必须从融合专家组定义的最全面代码点集以及默认全体标签变体评估规则集开始。有关生成专家组工作的完整描述可参见 LGR 程序 [PDF, 772 KB],尤其是 B.3 部分"变体规则生成程序"。

ICANN 会在 项目网站上为阿拉伯文生成专家组设立一个集中的公共工作空间,届时该专家组的文档、工作计划更新、公开报告、联系人详细信息以及所有其他相关信息都会保存在此。

为了强调文字机构群体参与制定 IDN 根区域 LGR 的重要性,同时也是为了提醒大家,在此,我们要再次提出负责制定根区域标签生成规则的生成专家组招募书。能否成功制定 IDN 根区域 LGR 取决于生成专家组是否了解根区域中所使用的各种文字。在 IDN 根区域 LGR 制定的第一阶段以及目前就阿拉伯文展开的种种努力中,生成专家组的任务是负责处理以下文字:希伯来文、中文、日文、韩文、西里尔字母、希腊文、拉丁文、孟加拉文、梵文、古吉拉特文、果鲁穆奇字母、僧伽罗文、泰米尔文、泰卢固文、泰文和格鲁吉亚文(即,在新 gTLD 和 IDN ccTLD 计划的现有申请中所使用的文字)。

有关如何成立生成专家组或如何表达个人或群体有意成立生成专家组之意向的更多信息,请参阅 负责制定根区域标签生成规则的生成专家组招募书,以及 根区域 LGR 项目网站上提供的其他支持文档。

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."
