Wikimedia Commons has a lot of artworks, but it is difficult to find and query them; they sit there if you know exactly what you want, but otherwise they collect digital dust. Wikidata has many artworks that can be queried, but is missing many that are already on Commons.<\/p>\n
If there were only some way to get a list of Commons artworks and check if they are on Wikidata, and otherwise create them there?<\/p>\n
Luckily, there is is a list<\/a> with Commons artworks that have no (known) Wikidata item, currently counting >7.8 million files. However, some of these are actually used on Wikidata, just as P18 (image) and not as “official” item.<\/p>\n This list is nice and all, but clearly overwhelming. Also, while there is a QuickStatements-gadget on some files, the created items are quite sparse, and there is the issue of determining if this artwork actually exists on Wikidata.<\/p>\n So I did my thing, and created three Mix’n’match catalogs, one for artworks<\/a>, one for artists<\/a> (where they can not be found on Wikidata automatically), and one for institutions<\/a> (again, only if no Wikidata item could be found). If an artist (or institution) is later matched by hand, the preliminary mappings to the artist catalog will be replaced by the “proper” Wikidata creator properties.<\/p>\n The Commons artwork scraper uses many parts of the Commons description page, preparing a nice item for creation (this will still need some manual looking after!). This example<\/a>, a painting by Tolouse-Lautrec, does not have a Wikidata item (at the time of writing this blog entry); neither does this one<\/a>.<\/p>\n I have a background job going through all 7.8 million files (minus the ones already used as an image on Wikidata), but that will take a while.<\/p>\n","protected":false},"excerpt":{"rendered":" Wikimedia Commons has a lot of artworks, but it is difficult to find and query them; they sit there if you know exactly what you want, but otherwise they collect digital dust.
