The Art Spore is a spore for a kind of Great Art Appendix, intended for topics that might be excluded from Wikipedia by the notability criteria, form or style (like use of media). In practice it is both to utilize and extend the Wikidata items as well as other resources like Wiki Commons.
"Galleries and artists' projects fall under notability criteria such as those on en.wiki. Art practice over recent decades has involved artist-run spaces, 'project spaces', infrastructures and pop-up initiatives. In the encyclopedia, articles on even quite well-established galleries have had difficulty showing sufficient reliable non-local 3rd party coverage to demonstrate they should survive a Deletion discussion. Can a complementary project capture a mapping of these spaces over time?"
