• What is exactly what you think needs documentation that is not covered in the Wikidata_Query_Service/User_Manual ?

Updated the task description.

this is out of scope and a ticket exists for it. just noting this is related work:

from brainstorm w loren: consider example queries as part of solving this use-case. to that end, perhaps including an example query to find all existing items would be useful for new users.

note: the key to making this task worthwhile is time-boxing our investment.

consider: a similarly scoped investment for quick statements.
