发布公众利益承诺 (PIC) 规范


在 2013 年 2 月 5 日的声明中,ICANN 要求新 gTLD 申请者提交 PIC 规范。PIC 规范为申请者提供了这样一个良机:即根据其申请中的陈述作出公众利益承诺,和/或作出未包括在申请中但计划予以的其他公众利益承诺。这些承诺将纳入该申请者的新 gTLD 注册管理机构协议中。

从今以后,公众将可以审核申请者提交的 PIC 规范。申请意见论坛将始终开放以接收关于申请的意见,包括对 PIC 规范的意见。

通过新 gTLD 微型网站上的"当前申请状态"页面可以查看 PIC 规范。如果申请中提交了 PIC 规范,则 PIC 一栏将显示"是"。单击链接即可下载该申请的 PIC 规范的 PDF 文件。要立即查看所有已提交的 PIC 规范,请单击"当前申请状态"页面上的"下载所有 PIC"链接。PIC 规范也可通过"申请详细信息"页面进行获取。

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."
