{{#SUBTITLE:Lingua Libre uses nor ISO 639-3 nor BCP47 but '''Wikidata Qids''' as internal identifier for a language. Currently, ISO 639-3 codes are used in two cases:
<br>• For the name of pages containing lists in the list namespace;
<br>• To forge Wikimedia Commons's category names

== Switching to other code ? ==

Changing the code would affect only those two parts of the process. If we switch from one language tag to an other, we would have to:
* Add a new property BCP47 locally as you suggested (a bot can import them from Wikidata);
* Rename all local lists (can be made by hand, we don't have many lists for now on);
* Rename all existing Wikimedia Commons categories and move all the audio recordings (a bot there is required);

== Other notable codes ==

* [[:en:BCP47|BCP47]] - prefered langtag in computational fields
* [[:en:ISO 639-3|ISO 639-3]] - most known langtag online
* [[:en:Ethnologue|Ethnologue / SIL codes (10th–14th editions)]]
* [[:en:Glottolog|Glottolog]] codes
