Perhaps it's a language confusion issue, but does Spain really have few lighthouses?  That would seem VERY unusual for a territory with an extensive coastline.

Or am I confusing cyber "reality" with real reality?  

Where does Wikidata sit in that mix?  How does it compare with DBpedia, Freebase, Wikipedia, or even *real* data sources like official governmental lists of navigational aids for mariners at sea?

Independent of where it sits now, what where does it aspire to sit?
