    dct:description "Lists the sub-spaces of a given space ref (space IRI + root definition) with their type and a link to the source nanopublication. Type and label come from each sub-space's root-definition assertion; sub-spaces whose definitions are all retracted or otherwise invalidated are filtered out. Ordered alphabetically by label. Pass the ref's root nanopub (root_np); the query resolves the ref via npa:rootNanopub and scopes the sub-space edges by the ref-level npa:hasSubSpace (subject = the ref), so it shows only that one ref's sub-spaces rather than merging all refs claiming the IRI. Ref-scoped variant of list-sub-spaces (which is IRI-keyed via npa:hasSubSpace on the space IRI).";
