导语:2025年4月22日,IANA的IDN实践库支持通过共享注册机构的IDN政策来发展国际化域名(IDNs),这些政策被称为标签生成规则集(LGRs)。
The Repository of IDN Practices supports the development of internationalized domain names (IDNs) by promoting the sharing of registry IDN policies known as Label Generation Rulesets (LGRs). These rulesets define Unicode code points permitted for registration and their associated rules. Registries implementing IDN support are encouraged to use this repository with some being contractually required by ICANN.
LGRs must include elements such as Script or Language Designator Version Number Effective Date and Registry Contact Details. They should be listed in formats like Label Generation Ruleset (RFC 7940) or ASCII/UTF-8 encoded text files following conventions from RFC 3743 and RFC 4290.
Delegated TLD registries can apply to register an LGR or update existing ones. gTLD submissions go through ICANN’s Naming Services portal while ccTLD and other submissions require approval from the Administrative Contact in the Root Zone Database. Requests must contain all necessary elements and should be sent to idntables@iana.org.
Language and script codes need to be specified when constructing LGRs. Common languages and scripts are listed with references to the IANA Language Subtag Registry and RFC 5646 for less common classifications.
