Hoi,
The consideration has been only is it a valid code. The question asked is a
different one. What is the point to all these codes that probably do not
bring anything to Wikidata.
Thanks,

I believe we should let the community decide that.

Hoi,
In the past we have been where we are now with Wikidata and new language
codes with new Wikipedias. The result was mayhem, and everything was just
as the "community" decided. The result is the many Wikipedias that have
no community. As a result the Language Committee took the place of "the
community"and from that moment new Wikipedias do conform to standards.

I have seen too many requests that are problematic that will in my opinion
not bring anything to Wikidata. I find a lack of purpose in what is
proposed. I do understand a purpose for texts as they were originally but
where is the purpose in adding labels that have arbitrarily transliterated
in other scripts.

There is no point. It is not the "community" supporting this it hidden in
phabricator.
Thanks,

GerardM

This is not about new languages for labels. This ticket and its subtickets are (almost all) explicitly about new languages for monolingual text values in statements. And Léa and I get asked a lot why this is being held up and we don't have a good answer. I don't want to do this but if this process isn't working I have to find another way in the interest of the project.

As I suggested above, I recommend reusing the language-data database for this. It is also used in the UniversalLanguageSelector, which is a dependency for Wikibase, so it's safe to assume that it's installed on Wikidata.

The criteria for adding a language to this database are pretty much the same as the general Wikimedia criteria. If anybody finds a discrepancy in the criteria, let me know.

What are the general Wikimedia criteria?

Now that I think of it, I'm not sure whether they are written anywhere :)

But a valid ISO 639 3 code is definitely a criterion. Is there anything else that Wikidata requires?

Wikidata's own criteria (from https://www.wikidata.org/wiki/Help:Monolingual_text_languages#Requirements_for_a_new_language_code) suggest that anything with a valid IETF language tag should be allowed. The requests so far have included ancient languages, artificial languages, country variants, script variants, other variants with a registered subtag and codes involving macrolanguages.

@Amire80 Would all of what Wikidata wants (see previous comment) be allowed in the language-data database?

@jhsoby I see you're also interested in using the language-data database instead, what do you think about the different types of codes in my previous comment?

Hello to all the subscribers of this task,
I'd like to raise awareness on this consultation about issues encountered when requesting new languages in Wikidata. Since this is directly connected to the process that currently goes through creating subtasks here, I thought you may want to give your opinion before we try to address the issues. Thanks a lot for taking a bit of time for this :)

Thanks a lot, and thanks for updating https://www.wikidata.org/wiki/Help:Monolingual_text_languages . I also updated https://www.wikidata.org/wiki/User:Lea_Lacroix_(WMDE)/List_of_lists_of_languages

We have created the Phabricator tag Language codes to track this (and other language code isuses), instead of using this unwieldy task. I have updated the instructions for requesting languages codes for monolingual text at Wikidata, and will add the instructions from this task to the project description.

You need to move all subtasks (including closed ones) to the subproject and remove them from this task - see https://www.mediawiki.org/wiki/Phabricator/Project_management/Tracking_tasks
