JOSM I18n contest 2025

[stoecker]

I started a new contest in 2025, as I'm really unhappy with the completeness of our translations:

StartupPage contains following text:

JOSM supports 41 languages beside English. But only 7 of these (German, Spanish, Dutch, Belarusian, Russian, Ukrainian and Portuguese) are above 99% completeness for JOSM core. Even such important languages as French are not. I hereby challenge the JOSM users to change that situation and let 2025 be the year of the JOSM I18n contest. See Translations (and the statistics table linked there).

This ticket should be used to track progress. For the contest I'll focus on the JOSM core translations, but I hope that also means the other places when JOSM needs I18n support aren't ignored.

I'll try to report progress here each or every second week as long as there is progress.

Changes:

• French people took the bait and translated everything. Yeah!
• Italian did nearly half the work to reach 100%

P.S. For everybody wanting to help: Automatic translation has become much better over the years: For me ​https://www.deepl.com e.g. speeds up the work, as in contrast to the situation in the past you now can use the translation with small modifications. Years ago it was much faster to translate text from scratch compared to correcting automatic translations.
