Get questions and answers about a resource
type: grlc-query
description: This query returns the questions asked about a resource (a space, a maintained resource, or any other entity, including part-level resources), together with who asked them and when, and their answers and other follow-up contributions. Questions are schema:Question nodes anchored to the resource via schema:about, following the Nanoarguments discourse model; answers are discourse contributions (schema:Statement) targeting the question via as:inReplyTo. Each answer is identified by its own nanopublication rather than by its statement node, so that several answers remain distinct even when the template they were created from reuses one statement IRI. Answers are listed one per line, each shown as the name of its author and the date, linking to the answer nanopublication. Retracted nanopublications and example nanopublications are excluded.
