Merged wikidata identifiers
In the wikidata dump we can find a collection of 1.3+m triples which indicate a owl:sameAs relationship between two wikidata items (e.g. http://www.wikidata.org/entity/Q39174590 owl:sameAs http://www.wikidata.org/entity/Q1778593).
Currently they are simply discarded. But they may become useful to switch to a streaming architecture as this would show merges!
