Hi! I'm currently working on the Norwegian part of WLM as part of a Wikipedian in Residence project with the Norwegian Directorate for Cultural Heritage (Riksantikvaren). To make things easier to link the objects with wikipedia articles on the three different "Norwegian" wikipedias (Norsk (bokmåls), Norsk (Nynorsk) and Sami) I've put in a proposal for an wikidata property for Kulturminnesøk (which is the directorates open access heritage database).

I was wondering if you guys had any experience/ideas about using wikidata with WLM.
