域名 RESTful Whois 服务器的开源参考实现 - 建议征求书


ICANN 今天发布了一份建议征求书 [PDF, 183 KB],用于确定能够提供域名 RESTful Whois 服务器的开源参考实现的提供商。

2012 年 5 月 15 日,互联网工程任务组 (IETF) 设立了一个新的工作组来使基于 RESTful 的注册数据访问协议实现标准化。为了推进域名注册管理机构和注册服务商替代协议的评估和通过,ICANN 正在征求有关开源参考实现的建议。

Whois 服务及其在国际化注册数据方面的效力是 ICANN 的重要问题。ICANN 一直致力于推动这一领域的发展,并对技术群体在过去和现在的贡献表示赞赏;继续与技术和政策群体合作,以改善 Whois 服务。

从 2002 年开始,ICANN 的安全与稳定咨询委员会 (SSAC) 就发布了各种说明需要改进 Whois 协议、服务和数据架构的公告,最新发布的公告是 SAC 051 [PDF, 237 KB]:SSAC 关于域名 Whois 术语和结构的报告。SAC 051 总结了以往的公告,并建议 ICANN 机构群体评估和采纳替代协议,该替代协议支持查询和显示国际化注册数据以及处理过去的 SSAC 公告中有关此主题的相关建议。

受访者需要对此 RFP 作出回应,回复地址为。提交有关此 RFP 的问题的截止日期为 2012 年 6 月 5 日。ICANN 将对受访者在 2012 年 6 月 7 日前提交的所有问题进行解答。对此 RFP 的最终回应将在 2012 年 6 月 15 日截止。

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."
