Hey, This seems like the wrong place do to that. I suggest to do this in the model itself, very similar to what we are doing with empty alias groups in lists of alias groups: https://github.com/wmde/WikibaseDataModel/blob/5c78e35ee1a382d3b132ddfd7607… Cheers -- Jeroen De Dauw - http://www.bn2vs.com Software craftsmanship advocate Evil software architect at Wikimedia Germany ~=[,,_,,]:3

Both edits are fairly recent and from two different editors. This looks fishy to me.

Hey, Last week a change to ignore empty references in lists of references was made: https://github.com/wmde/WikibaseDataModel/pull/399 This means that no new empty references can be added, and that existing ones will no longer be visible in most places. The one exception I can think of are dumps, since they use JSON generated before the change was made. Making a single edit to an entity that has an empty reference will fix it there as well though. Note that this change has not yet been deployed to Wikidata.org. Cheers -- Jeroen De Dauw - http://www.bn2vs.com Software craftsmanship advocate Developer at Wikimedia Germany ~=[,,_,,]:3
