Add name:sr-Latn (Serbian name in Latin alphabet) to recognised language codes

[Stereo]

What steps will reproduce the problem?

1. Tag an object with name:sr=Лебдјелица
2. Tag the object with name:sr-Latn=Lebdjelica

What is the expected result?

name:sr is shown as "Serbian" and name:sr-Latn is shown as "Serbian (Latin)"

What happens instead?

Only name:sr is recognised an a language in the list of tags.

Please provide any additional information below. Attach a screenshot if possible.

It's common for objects to be tagged with both. Conversion from Cyrillic to Latin is lossless; conversion from Latin to Cyrillic is lossy.

[Don-vip]

We have a few codes not matching our ISO 639-2/3 regex added in #16107/#16687:

name:ko-Latn (137016)
name:ar1 (98369)
name:ja_rm (98098)
name:sr-Latn (33508)
name:zh_pinyin (50276)
name:ja_kana (46640)
name:ja-Latn (39615)
name:ja-Hira (36681)

So we have:

• -Latn, -Hira for ISO 15924 Latin/Hiragana scripts (Latn, Hira)
• _kana for ISO 15924 Katakana script (Kana)
• _rm for rōmaji (romanization of Japanese)
• _pinyin for Pinyin (romanization of Standard Chinese)
• ar1 for a variant of Arabic? I can't find what is this code about

[Don-vip]

In 15501/josm:

fix #18284 - Add name:ko-Latn|ja_rm|sr-Latn|zh_pinyin|ja_kana|ja-Latn|ja-Hira to the list of known language codes

[stoecker]

I think you need to add a translators comment for these texts (before the text).

[Stereo]

I asked a non-mapper friend from Jordan about ar1. He says:

I would say ar is high Arabic and ar1 is a dialect. The pronunciation well change. But the map [from taginfo showing ar1 distribution] contains three dialects: Levant (Syria Lebanon Jordan Palestine), Arabic gulf and even the Iraqi dialect which can be split from the levant.

So we could have ar as Arabic, ar1 as Arabic (dialect)?

[stoecker]

Replying to Stereo:

So we could have ar as Arabic, ar1 as Arabic (dialect)?

It is not JOSM's task to invent new language codes. We should not support non standard codes. Especially not as ar1 does follow any useful convention.

[Stereo]

This wouldn't be inventing anything, only starting to document a tag that is used about 100k times around the globe. Yeah, we could and should have a better tag, but that's a different process.

[Don-vip]

I agree with Dirk, we should not in any way promote this exotic tag. There is not a single Arabic dialect but many:
​wikipedia:Varieties_of_Arabic#Modern_varieties

ISO 639-3 defines the following codes, people should use them:
