Lists, for a PART page (a resource viewed as a part of a maintained resource/space/user), the view displays configured on the part's owning resource, flagged for this specific part (read-only). Same display set and admin/maintainer authorization as list-view-displays, keyed on the owning resource (the 'resource' parameter): standalone view displays plus preset-contributed views, deactivations applied, each view resolved to its latest version. The shown_here column is a flag (check mark, else blank) indicating whether the view is shown on THIS part -- i.e. its appliesToInstancesOf matches one of the part's own classes (the 'partclass' multi-valued parameter), or it is pinned to the part via gen:appliesTo, or its namespace targeting covers the part's IRI (the 'partid' parameter). A hasTopLevelView preset is pinned to the owning resource's own page and is therefore never shown on a part (blank); a hasView preset falls back to the view's own targeting. For blank (not-shown) rows the target_multi_iri column lists the class(es)/namespace(s) the view targets. Rows are ordered shown-here first, then by structural position. Federation footprint (2026-08-20): endpoint rebased onto repo/full, so the former SERVICE hops to repo/full (preset branch) and to the ResourceView type repo (latest-version resolution) are local; only the space-state lookup remains federated, to repo/spaces (3 SERVICE clauses -> 1). The resolution was also rewritten from a run-once repo-wide max-date sub-select (which cannot see outer bindings and would enumerate the whole repository on repo/full) to bound per-view lookups choosing the same-key, non-invalidated supersedes-head with no newer such sibling -- same heads, ties preserved. Validated result-identical to the previous version across user/space/resource pages (group_concat token order, unspecified in SPARQL, may differ). The per-hop loopback federation was an amplifier of the rdf4j connection-pool deadlock behind the fleet-wide /api wedges.
