Motivation
[edit]Many WD items of mills in Germany (Austria and Switzerland) have no external identifier despite the cultural heritage monument ID (watermill, windmill). With milldatabase.org there is database maintained by the Deutsche Gesellschaft für Mühlenkunde und Mühlenerhaltung which is the umbrella organisation for molinology organizations in Germany. It seems valuable when we connect to it as it is already done to the Dutch database by P7789. – The preceding unsigned comment was added by Aschroet (talk • contribs) at 15:36, 24 May 2024 (UTC).

Support Akoopal (talk) 20:39, 30 May 2024 (UTC) This one will be useful. But good to mention that the scope of this database is really indeed worldwide, supported by TIMS. So it isn't restricted to the German and Austrian mills. If implemented I want to put effort to backfill this for the dutch mills.

- @Aschroet, Infrastruktur, Vicarage, Akoopal, Mjroots:
Done: Milldatabase ID (P12772). Regards Kirilloparma (talk) 15:00, 1 June 2024 (UTC)
Thanks Kirilloparma, just one thing: can we have a direct link to from the ID to the external site? --Arnd (talk) 15:55, 1 June 2024 (UTC)
- @Aschroet: This is a known cache issue when creating a new property. Links to external identifiers will become available within 24-48 hours (maybe even less), so don't worry if they are currently unavailable. You can later purge one of the Wikidata items using
?action=purge
command (example) so that the formatter URL is recognized. Regards Kirilloparma (talk) 16:45, 1 June 2024 (UTC)- Okay, another thing: The constraint: "Entities with statements for Milldatabase ID should also have a label at least in Dutch language." makes no sense i think. Maybe one could expect English. --Arnd (talk) 17:27, 1 June 2024 (UTC)
- If the database doesn't use Dutch, that makes sense, but I don't know the exact origin of these constraints. You should ask user who added them. Regards Kirilloparma (talk) 23:40, 1 June 2024 (UTC)
