I recently wrote about my work with Wikidata processing in my end of year review, as Putting the Data Model on the Map.
The key idea (and technical hurdle to clear) was handling Map types, as discussed in that post. Once we're past that, the next obvious question is what's in Wikidata? Where does this take us, what can we do once we get all known Wikidata into a more amenable form?
To be continued...
