Hi Lydia, in languages such as OWL, a class of item can be defined by a predicate on the properties and values of the item. Will we be able to link a class Qitem to a Wikidata complex query in the corresponding namespace ? For example if we define a class "Douglas Adams Novels" whose instances are the members of the example query you gave ?
