Pass the ref's root nanopub (root_np). Per (member, role) only the latest role-instantiation nanopub is returned (by dct:created), so a role re-asserted several times shows once. Unlike list-space-observers (validated-only), this also includes self-declared observers whose key is not trust-validated (no accepted introduction), flagging them in the headerless ?unverified_noheader column. The role label is pinned to the role the space actually assigned (RoleAssignment), correct even when several declarations share a property. Ref-scoped; shows un-introduced observers rather than hiding them. v3: (a) resolves owl:sameAs space aliases (via the ref's validated npa:sameAsSpace edges in the current-state graph), so an observer role declared against an alias IRI of the space is included; (b) no longer hides users who also hold a higher-tier (admin/maintainer/member) role — every observer-tier association is listed, so an admin who is also a participant appears here for that participant role. The built-in admin property gen:hasAdmin is still excluded (it is not an observer-tier association), as are roles whose declaration is itself admin/maintainer/member-tier; non-approved higher-tier claims belong in list-space-non-approved. v4: the invalidation filter now honours an npx:invalidates edge only when the invalidating nanopub shares a signing pubkey (npa:hasValidSignatureForPublicKeyHash) with the grant it targets, so a foreign-key retraction can no longer erase another agent's observer association (issue #487 / same gate as the materializer's #112). v5: BUGFIX — the v3/v4 space-alias resolution used a `{ bind(?spaceIri as ?inSpace) } union { ... npa:sameAsSpace ... }` pattern, but RDF4J does not propagate the outer ?spaceIri into a BIND inside a UNION branch, so ?inSpace was left unbound and the query returned ZERO observers for every space. Replaced with a non-union `filter( ?inSpace = ?spaceIri || exists { ... npa:sameAsSpace ... } )` that binds ?inSpace from the role-instantiation triple, restoring the observer list while keeping alias resolution. https://w3id.org/np/RAUQdhb2lwrSA6Vqv96ERyISUhO9U9eOFNWsSe9NMwiWE/list-space-observers http://purl.org/dc/terms/license http://www.apache.org/licenses/LICENSE-2.0 https://w3id.org/np/RAUQdhb2lwrSA6Vqv96ERyISUhO9U9eOFNWsSe9NMwiWE/list-space-observers http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/kpxl/grlc/grlc-query https://w3id.org/np/RAUQdhb2lwrSA6Vqv96ERyISUhO9U9eOFNWsSe9NMwiWE/list-space-observers http://www.w3.org/2000/01/rdf-schema#label List space observers (ref-scoped, all observer-tier associations, with validation flag) https://w3id.org/np/RAUQdhb2lwrSA6Vqv96ERyISUhO9U9eOFNWsSe9NMwiWE/list-space-observers https://w3id.org/kpxl/grlc/endpoint https://w3id.org/np/l/nanopub-query-1.1/repo/spaces https://w3id.org/np/RAUQdhb2lwrSA6Vqv96ERyISUhO9U9eOFNWsSe9NMwiWE/list-space-observers https://w3id.org/kpxl/grlc/sparql prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> prefix dct: <http://purl.org/dc/terms/> prefix np: <http://www.nanopub.org/nschema#> prefix npa: <http://purl.org/nanopub/admin/> prefix npx: <http://purl.org/nanopub/x/> prefix gen: <https://w3id.org/kpxl/gen/terms/> prefix schema: <http://schema.org/> select ?member (group_concat(distinct ?latestNp;
