IANA Language Subtag Registry Schema

Overview

The IANA Language Subtag Registry defines the language, region, script and variant codes used in RFC5646. The format for this data is a custom format, for example:

%%
Type: language
Subtag: af
Description: Afrikaans
Added: 2005-10-16
Suppress-Script: Latn

This schema defines a way of expressing this information in RDF so that it can be queried using RDF tools.

The RDF class associated with a subtag code is determined by the Type and Scope properties as follows:

Type	Scope	RDF Class
extlang		ExtLang
grandfathered		Grandfathered
language		Language
language	collection	Collection
language	macrolanguage	MacroLanguage
language	special	Special
language	private-use	N/A¹
private²		Private
redundant		Redundant
region		Region
script		Script
variant		Variant

The private-use scope defines the range of language codes which are reserved for private use and as such do not define a specific language code to associate a class with.
The private type is not an official IANA type. It is used to describe subtags in the -x- part of the language tag reserved for private use. This differs from the range of private use language, region and script codes.

The remaining properties are mapped to the following RDF properties:

IANA Property	RDF Property
Added	added
Comments	comments
Deprecated	deprecated
Description	label
Macrolanguage	macrolanguage
Preferred-Value	preferredValue
Prefix	prefix
Subtag	subtag
Supress-Script	supressScript
