English Wiktionary's languages, language families and scripts, for Kotlin Multiplatform, Java, Swift, Python, TypeScript, Go and Rust, and as SQL: every code Wiktionary uses, what it calls each one, and how they relate, built into the library so nothing is asked of the wiki.

val english = Language.of("en")
english.name                                  // "English"
english.family?.name                          // "Anglic"
english.ancestors.map { it.name }             // [Early Modern English]
Language.named("Old English")?.code           // "ang"
LanguageFamily.of("ine").protoLanguage?.name  // "Proto-Indo-European"
Script.of("Deva").nameFor(Language.of("mr"))  // "Balbodh"
Language.of("zh").detectScript("語言")         // Traditional Han (Hant)
