标签生成规则 (LGR) 工具包开发提案征询

Why this matters

The Internet Corporation for Assigned Names and Numbers ("ICANN") is seeking a provider to design and develop software for creating, using and managing Label Generation Rulesets (LGRs) based on a new machine readable format based on the formal representation

互联网名称与数字地址分配机构 (ICANN) 现征召一名软件设计开发提供商,根据以下链接中规定的新型机读式正式表述方式的原则来创建、使用并管理标签生成规则 (LGR)

ICANN 预计最迟将在 2015 年 5 月前签署合约,启动这一工作。

ICANN 下属的 IANA 部门托管着一批语言和文字特殊数据字汇。域名注册管理机构则可使用这些字汇来生成标签,即通常人们熟知的 IDN 列表,现又称标签生成规则 (LGR)。人们正在设计基于 XML 的新型机读格式,以组织并表述 LGR 的数据。本格式还可用于根区中的 LGR,以验证潜在可用的顶级域名 (TLD),并确定现有和潜在可用标签的变体。根区 LGR 目前则由不同文字社群通过合作的方式来编制(成立以文字为基础的生成专家组)。

ICANN 有意发布带有开放源使用许可的软件,方便社群使用和内部运营。

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."
