标识符技术健康指标 (ITHI) 常见问题解答

您有兴趣了解标识符技术健康指标 (Identifier Technologies Health Indicators, ITHI) 项目吗?请点击下方图片查看我们的信息图表,该图描述了 ITHI 的定义及好处。

什么是标识符技术健康指标 (ITHI) 项目?

什么是 ITHI?

标识符技术健康指标 (ITHI) 是 ICANN 倡导的一项举措,旨在衡量由 ICANN 助力协调的标识符系统的"健康状况"。ICANN 推行这项举措是为了制定一系列指标,并在一定时间范围内测量和跟踪这些指标,以确定标识符系统总体上运行得更好还是更差。这是一个长期项目,预计将持续数年。

ITHI 项目的适用范围是什么?

ITHI 的适用范围包括 ICANN 助力协调的所有互联网唯一标识符。

ITHI 项目的运行时间框架是什么?

2016 年 3 月 9 日,在马拉喀什召开的 ICANN 第 55 届大会的公开会议上,ITHI 项目正式启动。我们期待与有关社群不断开展合作,以制定相关指标并长期跟踪这些指标。数据收集是 ICANN 持续进行的一项工作。

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."
