Hoi,
For many categories we have exactly that in Reasonator. This
functionality is based on "is a list of".
Yes, I was thinking of this when making this proposal. The thing is that
"is a list of" is not a very powerful way to describe lists. It can only
do very simple things. Examples like the "list of inventors killed by
their own invention", which are easy to do in SPARQL, are not possible
there.
I should add that there are also problems with having arbitrary SPARQL
queries. They are on the other end of the sprectrum from where "is a
list of" is: they can express too much details (sorting order, label
recall, query optimiser settings, etc.). When using SPARQL for list
descriptions, the community should try to use the simplest query
possible without any extras for formatting and sorting, or it will again
be hard to use this.

It functions not for all
categories or all content for a category. Wikidata often shows more data
particularly when the categories from "other" Wikipedias have been
harvested.
It would be relatively easy to continuously harvest data from Wikipedias
based on such categories.
Thanks,

If you could store queries, you could also store queries for
each item that is about a list of things, so that the query
returns exactly the things that should be in the list ... could
be useful.
This also applies to a huge number of Wikipedia categories (the non
subjective ones). It would be extremely useful to have queries
describing them attached to the Wikidata items for the categories.

Subject: Re: [Wikidata] A property to exemplify SPARQL queries
associated witha property
Hi!
Relaying a question from a brief discussion on
Twitter [1], I
am curious
to hear how people feel about the idea of
creating a a "SPARQL
query
example" property for properties, modeled
after "Wikidata property
example" [2]?
Might be nice, but we need a good way to present the query in the UI
(see below).
This would allow people to discover queries that
exemplify how the
property is used in practice. Does the approach make sense or
would it
stretch too much the scope of properties of
properties? Are
there better
ways to reference SPARQL examples and bring them
closer to
their source?
I think it may be a good idea to start thinking about some way of
storing queries on Wikidata maybe? On one hand, they are just
strings,
on the other hand, they are code - like CSS or Javascript - and
storing
them just as strings may be inconvenient. Maybe .sparql file
extension
handler like we have for .js and .json and so on?
