hi,
we are currently experimenting to have, after zb zürich earlier the year[1], a second museum from switzerland uploading full quality images (i.e. tif format)[2]. i was wondering what is the most "wikidata compatible" way of adding a creator information to an image like this one: https://commons.wikimedia.org/wiki/File:Soleure_Aa_0012.tif
the painter winterlin is in the category, has a template including personal information, just like the wikipedia article, and the wikidata entry.
