I'm not saying that the results yielded by "Category:Books by Jean-Paul Sartre" or "Category:Books by J.R.R. Tolkien" are or should be the same as the result yielded by a corresponding Wikidata query, but the concepts they represent, they are the same. Ditto for lists. (As a further clarification, I didn't mention anything about changing Wikipedia categories or Wikipedia lists either.)
My question was regarding the functionality of WD items associated with Wikipedia categories and Wikipedia lists. Conceptually those items represent (or can represent) queries. WDQ, the tool by Magnus, already can interpret certain statements as queries [1]. Would it make sense to replicate that functionality on Wikidata?
Cheers, Micru

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).
If the plan is to change the way categories are used in Wikipedia and the other Wikimedia wikis, I'd say this is a very different goal, but should be discussed on those wikis.
List-articles often contain much more love and care than a Wikidata query result will for a while. I don't think that replacing an article like the list of books by David Foster Wallace [3] the List of US Presidents [4] with a single simple query is a short-term goal.

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?

I would like to make you aware of this RFC started by Gerard:
https://www.wikidata.org/wiki/Wikidata:Requests_for_comment/Define_lists_on_...
It is interesting because in the end, what is the difference between a
list,
a category, and a query? Not much, really.
I'm curious to know if the approach taken with queries will be the
same as
the WDQ http://tools.wmflabs.org/reasonator/?&q=6573995
Items like "List of..." or "Category:" would have some use, but the development notes don't state if this is the intended path https://meta.wikimedia.org/wiki/Wikidata/Development/Queries
Any thoughts about it?
I've been trying to understand the RfC 3 times now and still fail. So 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)
