I've removed the mapping for gsw/als. I added it based on a request on the talk page of the gadget.

Structured data has been cleaned too.

Checked the current live code and issue has already been fixed somewhere in the past.
So it's only correcting existing data.
For the information template this has been fixed.
For the Structured data I filed a Bot request: https://commons.wikimedia.org/wiki/Commons:Bots/Work_requests#Replace_Date=1970-01-01_in_Structured_Data_of_Wikiportret_uploads

In the end the users uploading the file to commons are responsible. (This includes me). On uploading the file, a pre-filled template is placed in the text field. The users needs to fill in the missing information, categories and press submit. (I must admit there are uploads by me in the search results, so I have been negligent too)
And the date isn't invented from scratch. Unix timestamp 0 is 1970-01-01.
I'll make sure that in a new version of Wikiportret the date field is emtpy if it's 1970-01-01

Just tried it with safemode=1 and then the issue doesn't occur. So it's a gadget or userscript that causes the issue.
Disabled all my userscripts and enabled them 1 by 1.
No problems, until I enabled User:Magnus_Manske/authority_control.js by @Magnus

I need to adjust my script so it sends mail using the smtp server for tools.
And I need to migrate my wget command to curl, but that's an easy fix.

@Manuel: The term termbox languages means Labels/Aliases/Descriptions. When added, they are also available for Monolingual properties. They won't become available for Lexemes on the other hand.

As Toki Pona is well-attested and seems to have quite some traction, I (as a LangCom member) support adding it for both lexemes and monolingual.

What is the next step in getting support for Toki Pona added? The previously mentioned pull request already got merged.

@Amire80 @jhsoby What do you say?

@Nikki What is the autonym for this language? Because I need to know this to add the language to InitialiseSettings.php (see T277836)

In T293884#7467903, @Lucas_Werkmeister_WMDE wrote:

In Wikibase, yes, but @Mbch331’s changes also add the language to wmgExtraLanguageNames, where the autonym is included. (Eventually we’ll hopefully get rid of that – see T273627 – but depending on where the autonym is used, maybe we’ll add the autonyms to the Wikibase config. I’m not sure.)

There is a very big problem to need a languages codes. There is so many languages without it AND it’s always little language used by minorities. It’s terribly difficult to help, describe and write in these language here, when it shouldn't.

But is there a real use case for monolingual properties in those languages? If there's only a one time use, then you should use mis (miscellaneous), because changing the code so minority languages can be used will make this a significant change.
If there are valid use cases then please provide them, so WMDE can make a better judgment if it's worth changing the code to make this possible.

Besides langcom approval, we also need language codes. So far only Gallo has been provided.

From T263946 it looks like it followed the usual process for new codes for Wikidata. Also it was tested/marked as resolved by WMDE staff.

@Esc3300 LocalNamesEn.php is part of CLDR. That's not a WMDE extension.
The corresponding change was approved by @Raymond and not WMDE

It's not the query service gui that adds the +
When you use the bigdata interface the + gets added as well.

The problem is that the + gets encoded again. It becomes %2B

Thanks for taking the time to report this. Could someone please explain where to see a "Patrol button" in the screenshots, and provide links where someone else can see a problem? @Jonathan5566: Please see https://www.mediawiki.org/wiki/How_to_report_a_bug - thanks!

@jhsoby @Amire80; What do you say?

@Eugene233 When requesting new languages always specify what you want to use them for: Monolingual properties or Lexemes or Labels/Description/Aliases as the developer needs to know where to add them in the code.
If you want to use the language outside Wikidata, you need to contact LangCom (not via Phabricator) what you need to do to get the language added for use on all Wikimedia projects.

Seems to be live, at least nan-hani

@Amire80 @jhsoby @Esc3300 @Nikki Could you please reach an agreement on what the desired language code is going to be? I'll make a new patch then.

I think the discussion here becomes more complex than it should be. How many labels do we actually expect to have here? If we just start with "mix", and then we get a lot of them, can they be later divided by someone who understands these languages well?

It's actually missing in LocalNamesEn which probably explains why we get the Spanish version.

@Amire80 What's your view on this?

@Mbch331, I see mvf in the code of WikibaseLexeme, but I cannot actually add lexemes in it. And I don't see it in the code of Wikibase at all. Can you add it please?

As the current Wikidata-Campsite (Wikidata-Campsite-Iteration-∞ (On Hold)) unstaller, what is this task stalled on?

This is blocked on LangCom approval for the remaining languages.

Don't we already have this? I don't think we allow adding terms for simple for example? Or am I missing something?

@Esc3300 My patch was denied for 2 reasons:

1. I used da instead of nl (which has been fixed)
2. There is not enough proof of consensus in this task (this is something I can't fix.

Added missing translations. Language codes that are present in CLDR need to be updated upstream, language codes not present in CLDR can be added to LocalNamesNl.php

Since there is only approval for mix in case of Mixtepec Mixtec and no approval for mix-und, this isn't ready to go. Still needs LangCom approval. @jhsoby @Amire80 is mix-und a good alternative for this case where it's unknown which form of Mixtec is used?

Another wonder : monolingual language code does not necessarily mean there would be a new line "gsw-fr" as labels for items, does it?

No. It's only available for monolingual properties. Labels/aliases/descriptions aren't properties and thus not supported. If it's needed, a new ticket is needed for that.

As an exemplle, from :

{{lang|cmg-Mon|ᠮᠣᠩᠭᠣᠯ ᠪᠢᠴᠢᠭ}} this is the name of the Mongolian script in classical and modern Mongolian.

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

It's about LocalNamesSco.php only.

Ideally these changes should be added to Cldr
