FAIRsharing record for: ISO 639-3 Codes for the representation of names of languages - Part 3: Alpha-3 code for comprehensive coverage of languages

This FAIRsharing record describes: ISO 639-3 provides a comprehensive set of identifiers for all languages for use in a wide range of applications, including linguistics, lexicography and internationalization of information systems. It attempts to represent all known full languages. ISO 639 provides three language code sets: one is a two-letter code (ISO 639-1) and two others are three-letter codes (ISO 639-2 and ISO 639-3) for the representation of names of languages. The three-letter codes in ISO 639-2 and ISO 639-3 are complementary and compatible. The two codes have been devised for different purposes. The set of individual languages listed in ISO 639-2 is a subset of those listed in ISO 639-3. The codes differ in that ISO 639-2 includes code elements representing some individual languages and also collections of languages, while ISO 639-3 includes code elements for all known individual languages but not for collections of languages. Overall, the set of individual languages listed in ISO 639-3 is much larger than the set of individual languages listed in ISO 639-2.

本FAIRsharing记录介绍的内容如下：ISO 639-3为所有语言提供一套全面的标识符，可广泛应用于语言学、词典编纂以及信息系统国际化等诸多领域，旨在覆盖所有已知的完整语言。ISO 639共提供三套语言编码集：一套为双字母编码（ISO 639-1），另外两套为三字母编码（ISO 639-2与ISO 639-3），用于表示语言名称。ISO 639-2与ISO 639-3所使用的三字母编码互为补充且兼容，二者的设计初衷各不相同。ISO 639-2中收录的单一语言条目是ISO 639-3收录条目的子集，二者编码的差异在于：ISO 639-2既包含部分单一语言的编码元素，也包含语言集合的编码元素；而ISO 639-3仅涵盖所有已知单一语言的编码元素，不包含语言集合的编码元素。总体而言，ISO 639-3收录的单一语言条目数量远多于ISO 639-2。
