The community needs to develop an active test project; it must remain active until approval (automated statistics, recent changes). It is generally considered active if the analysis lists at least three active, not-grayed-out editors listed in the sections for the previous few months.
"Wikidata talk" (the discussion namespace of the project namespace)
Default is "no". Preferably, files should be uploaded to Commons.
If you want, you can enable local file uploading, either by any user ("yes") or by administrators only ("admin").
Notes: (1) This setting can be changed afterwards. The setting can only be "yes" or "admin" at approval if the test creates an Exemption Doctrine Policy (EDP) first. (2) Files on Commons can be used on all Wikis. (3) Uploading fair-use images is not allowed on Commons (more info). (4) Localisation to your language may be insufficient on Commons.

I would like to be able to add labels and descriptions to Wikidata in Cape Verdean Creole (I'm a native speaker), and currently if I try it, Wikidata gives me an error saying the language code 'kea' is not recognized. --Waldir (talk) 17:43, 9 May 2014 (UTC)
This proposal seems to be misplaced. It is not a request for a new project. PiRSquared17 (talk) 17:49, 9 May 2014 (UTC)
I know, I was puzzled myself, but GerardM told me this was the way to do it (i.e. to request support for a new language in Wikidata). --Waldir (talk) 17:59, 9 May 2014 (UTC)
Since he's on LangCom, I guess he's right about this, but it is a strange place to request it. According to this blog post, any language with an ISO 639-3 code is permitted; I do not see the need for a Meta request. PiRSquared17 (talk) 18:20, 9 May 2014 (UTC)
In principle any language with an ISO-639-3 code is eligible however, it still requires the language to be considered eligible. A language will not be enabled only because someone has an interest in it. The objective is to prevent the "wealth" of new languages that made Wikipedia look like a stamp collection.

If the proposal is misplaced here, then where is the right place? Many months ago I tried to ask for Northern Thai to be added for Wikidata at Talk:Language committee, but it was completely ignored there as well. Ahoerstemeier (talk) 14:19, 29 September 2014 (UTC)
