What's langco's view on this ? @Amire80 @jhsoby

LangcoM.

Looks good to me, I guess, although I am curious about the source. Do these appear in a dictionary?

Very few are in the shorter dictionary (I don't have access to the large one at the moment). The list is from the Scots Language Centre, though, and I think can be treated as reasonably authoritative.

A couple more to confirm - la is "Laitin" per the *Essential Scots Dictionary*; ru is "Roushien"; gd is "Scots Gaelic", both from the SLC list. So ru needs to change, la and gh can stay the same.

Do we have a list of *all* language codes with a sco translation? I'm happy to go through the rest of the list to check, I'm just not quite sure where to find it.

While it's good to have more review on language configuration, I'm actually not sure why is the Language committee mentioned here at all. I don't think there's a rule about it ;)

And I'm not sure why is Wikidata mentioned either.

If I understand correctly, T162406 is about CLDR. Ideally, all these changes should eventually be in upstream CLDR and not in local MediaWiki code.

@Raymond, @Nikerabbit, and @Nemo_bis can give much better CLDR guidance than I can.

Ok. One of its members was involved when these were first defined ( T162406), but I wont ask going forward. I will update T284915 as well.

And I'm not sure why is Wikidata mentioned either.

As for language codes, Wikidata seems to be the primary consumer for this (you know the wiki about interwikis!). Thus T162406 in the first place.

It's about LocalNamesSco.php only.

It really depends how much of the interface at Wikidata you want to be translated into sco. The language names appear prominently on every item when using "?uselang=sco" or switching to "sco".

Ideally these changes should be added to Cldr

@Aklapper apparently it's preferred not to use the Due Date feature, but please avoid writing things like "random Due Dates".

Thanks for the patch @Mbch331 !
