But that's simply not the case. The Category:Books by Jean-Paul Sartre [1] or Category:Books by J.R.R. Tolkien [2} neither are a complete list of books by those authors (e.g. Sartre's fictional books are missing, Tolkien's non-fictional *and* Middle earth books are missing), nor are they only including books by Tolkien (e.g. they also include templates and other categories, which are likely not written by Sartre or Tolkien).
The point I wanted to make (following your example), is that the Wikidata Query "All novels by Douglas Adams" is equivalent to the item "Category:Novels by Douglas Adams" [1]. In other cases there will be even 3 items representing the same information: the wd query, the category item, and a "list of..." item. So I'm just wondering if this complexity is really needed for structural/technical reasons.
Maybe there is an easier way instead of linking to the wd query with a "category's main query" property?Cheers,Micru

I can't answer your questions unfortunately.
The short and simplified version of how complex queries will work:
* someone defines a query on a page in a special query namespace (eg
"everything that has author = Douglas Adams")
* the result of the query is a list of items matching the query
* the Wikipedias can include the result of the query and visualize it
in certain ways on a page. (eg the wikitext of the article "List of
works by Douglas Adams" would have a call to include the query result
from Wikidata)
