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

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)
