As an editor I want to query for values that link to Items in order to query for basic important data.
We currently don't allow selecting Items in the value part of the query. A lot of basic and important queries ("instance of:country" etc) require it however. We need to support Item values.
- Instance of: country
- gender: female
GIVEN a visual query
WHEN selecting a Property of datatype Item
THEN I can select Items in the value field of the query
- correct SPARQL code is generated
- type-ahead suggestions are available similar to current input on Wikidata (including input of Q-ID instead of label)
- only existing Items are suggested and can be selected
- We use the lookup component for the value input
