Extension:WikibaseWikidataType/en

The WikibaseWikidataType extension adds new DataType named wikidata-item to Wikibase which allows Properties to reference Wikidata items.

Currently this extension manages to add a new DataType which can be assigned to a Property, but upon trying to add the new Property to an Item you will receive the following message: Handling of values for "wikidata-item" data type is not yet supported.

I am still working out how to fix this issue and allow you to actually enter data. Documentation on how to add new DataTypes to Wikidata seems pretty sparse from what I can see.
