Filtered server-side to declarations signed by an admin or maintainer of the owning space, or by the affected user themselves (for an agent's own page). Each referenced view is resolved to its latest version by following the npx:supersedes chain: among the version tree's current heads (nanopubs that are themselves neither superseded nor validly retracted via npx:invalidates), the most recent is chosen, so ?view is the latest non-retracted view definition (no separate latest-version lookup needed by the client). Choosing a current head rather than the max-timestamp node makes resolution robust to backdated supersedes and to retracted versions. Preset-derived rows have an unbound ?display and carry the resolved ?view plus the assignment's activation mode. The view-version resolution is wrapped in a run-once sub-SELECT so it is evaluated once for the whole view set rather than once per referenced view. Space-governed versions (gen:governedBy, nanodash docs/views-and-presets-as-maintained-resources.md): a referenced version declaring gen:governedBy resolves to the newest version of its (kind, space) pair signed by a current member+ (admin/maintainer/member) of that space -- with the kind validated as a maintained resource of the space -- taking precedence over the supersedes-based head; without a valid governed candidate the pinned version stands. Federation footprint (2026-08-20): the query now runs on the repo/full endpoint, so the former SERVICE hops to repo/full (preset branch) and to the ResourceView type repo (view lookups, governed candidates) are plain local patterns; only the two lookups of materialized space state (authority gate, governed-signer validation) remain federated, to repo/spaces. The previous 5-SERVICE layout was the main amplifier of a connection-pool deadlock in the query service's loopback federation (an outer query holds a pooled connection while each SERVICE hop -- one per binding under a nested-loop join -- requests another from the same pool): a thread dump during a production wedge showed all 60 route connections held by result streamers of exactly these hops. Validated byte-for-byte identical to the previous version across resources covering standalone displays, preset assignments, governed views, an agent's own page, and rival space refs. https://w3id.org/np/RAWlJqJ5afOTN0AIDP3rnSCysQer9B4pmSC6QbzssTAyc/get-view-displays http://purl.org/dc/terms/license http://www.apache.org/licenses/LICENSE-2.0 https://w3id.org/np/RAWlJqJ5afOTN0AIDP3rnSCysQer9B4pmSC6QbzssTAyc/get-view-displays http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/kpxl/grlc/grlc-query https://w3id.org/np/RAWlJqJ5afOTN0AIDP3rnSCysQer9B4pmSC6QbzssTAyc/get-view-displays http://www.w3.org/2000/01/rdf-schema#label Get view displays https://w3id.org/np/RAWlJqJ5afOTN0AIDP3rnSCysQer9B4pmSC6QbzssTAyc/get-view-displays https://w3id.org/kpxl/grlc/endpoint https://w3id.org/np/l/nanopub-query-1.1/repo/full https://w3id.org/np/RAWlJqJ5afOTN0AIDP3rnSCysQer9B4pmSC6QbzssTAyc/get-view-displays 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/> select distinct ?display ?view (coalesce(?viewKindOptional, ?view) as ?viewKind) ?label ?displayType ?displayMode ?np ?pubkey ?date where { values ?_resource_multi_iri {} service <https://w3id.org/np/l/nanopub-query-1.1/repo/spaces> { graph npa:graph { npa:thisRepo npa:hasCurrentSpaceState ?stateG . } { # Authority gate (issue #130 / nanodash#510): a single mandatory hop through the # governing space ref, which covers both a maintained resource and a space itself # (the reflexive self-edge), keyed on the role tier materialized on the # RoleInstantiation since #125.
