Hi @Mbch331 I have seen the example mentioned above and the list of language codes (https://www.wikidata.org/wiki/Help:Wikimedia_language_codes/lists/all).
gml is already added in this list but is not showing as a language code in the example . Can you tell me what exactly needs to be done? I'm very new to opensource. Thanks!
Wikibase had a property of the type Monolingual languages. They use the default languages available by Wikimedia and a few extra languages that aren't in the default list.
The list you refer to isn't related to this request.
It needs a code change in Wikibase.
You need to change the file lib/includes/WikibaseContentLanguages.php in https://gerrit.wikimedia.org/r/mediawiki/extensions/Wikibase
@Diwanshu885 No need to start tagging people on Gerrit. It's been brought to the attention of the correct people. It will get reviewed. No need to rush. Code deployment is only once a week, so whether it gets merged now, later today or tomorrow doesn't matter. Change won't go live till next week.
