17 January 2017 I get this nice reminder by Wikidata user Pasleim: Unused properties This is a kind reminder that the following properties were created more than six months ago: Artsy gene (P2411), J. Paul Getty Museum object id (P2582), dataset distribution (P2702). As of today, these properties are used on less than five items. As the proposer of these properties you probably want to change the unfortunate situation by adding a few statements to items.
I went ahead and added a few Getty Museum IDs by hand. Then I looked more closely at the available data and it hit me: let's do some SPARQL queries to generate the missing data.
