Wikidata is a rich source of metadata, for example
https://www.wikidata.org/wiki/Q1219561

Would anyone be interested in having more of that metadata imported?
For example, wikidata tags works as novels, plays, poems, etc.
It tags these literary works with one or more genre tags as well.
I could import this metadata either into the existing tags column or a user defined column.
Is there other metadata that people would want?
