Maybe this is a super easy question, but I did not find a solution yet: How can I import the metadata for one image from Wikimedia (for ex. File:Bundesarchiv Bild 183-1988-0912-400, Berlin, Übergabe der 1-Megabit-Speicherschaltkreise.jpg - Wikimedia Commons ) to an image in Tropy?
There’s no better way to do this, unfortunately, than copying the data for all fields of interest. It might be a worthwhile idea though to write an import plugin to fetch wikimedia data via the API.
