I've done that; but it has only reduced the number of results to 3,456 - what else needs changing?

Surely the uniqueness works in the other direction? A UID identifies one unique subject; the subject can have multiple UIDs. -- Andy Mabbett @pigsonthewing http://pigsonthewing.org.uk _______________________________________________ Wikidata mailing list Wikidata@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata
