阿拉伯文国际化域名任务组 (TF-AIDN) 是一个以社群为主导的工作组。它由 ICANN 中东战略工作组 (MESWG) 于 2013 年成立,致力于解决技术问题和解决方案。TF-AIDN 推动阿拉伯文 IDN 及其安全部署。

目前,TF-AIDN 拥有 35 位成员,他们来自全球的 18 个国家/地区,并组成了阿拉伯文生成专家组。该任务组的成员有着不同的背景 — 包括语言学、技术和政策 — 并涵盖使用阿拉伯文的广泛亚洲和非洲语言。

由于 TF-AIDN 成员的真诚奉献,TF-AIDN 是第一个完成了顶级域根区标签生成规则 (RZ-LGR) 提案的生成专家组。TF-AIDN 也完成了阿拉伯语和乌尔都语二级域的 LGR 提案,供社群参考使用。

目前,TF-AIDN 正在完成波斯语和普什图语的二级域 LGR 工作。此外,该任务组正在联系当地的斯瓦希里语、富拉语和其他主要非洲语言的专家,为其使用阿拉伯文域名提出二级域 LGR 提案。

TF-AIDN 就普遍适用性展开了广泛的工作。最近,任务组完成了有关使用阿拉伯文的语言遇到的问题的第一份使用案例报告,并将会把该报告呈交给普遍适用性指导小组 (UASG)。与阿拉伯文域名有关的一些关键普遍适用性问题有:

  • 阿拉伯文域名从右至左的书写方向
  • 端对端发送电子邮件至使用阿拉伯文的电子邮件地址
  • 针对使用阿拉伯文域名和电子邮件地址的操作软件评估
  • 域名系统安全性问题,特别是与阿拉伯文 IDN 及其变体域名有关的安全性问题
  • 编程语言和框架与阿拉伯文域名的一致性
  • 与自动在文本中生成电子邮件和 URL 链接的应用程序有关的一些挑战

对阿拉伯文 IDN 感兴趣的志愿者都可以成为 TF-AIDN 成员。我们的成员资格是开放的 — 如果您想加入,请发电子邮件至 联系我们。


    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."
