Takes the definition's kind (its dct:isVersionOf target; kind), the space named by the pinned version's gen:governedBy (space), and the nanopublication URI of the pinned version (pin). If the kind is registered as a maintained resource of the space (npa:isMaintainedBy in the current space state), the result is the newest version of the (kind, space) pair: a nanopublication that npx:embeds the version, which declares dct:isVersionOf <kind> and gen:governedBy <space>, is signed by a current member+ (admin/maintainer/member, not observer) of the space's governing ref, and is not invalidated by its own key (mode 'governed'). Without such a version the result is empty and the caller keeps its pin, which is not re-validated here. If the kind is not registered for the space, gen:governedBy has no effect and the pin resolves like an ungoverned version (mode 'supersedes'): the single current head of its npx:supersedes chain, signed with the pin's own key and not invalidated by it. This is the same rule as get-latest-version-of-np, so a chain that has forked into several heads yields no row. Returns at most one row: version (the embedded definition IRI, or the nanopublication URI if it embeds none), date, np and mode. Hosted on the spaces repo; the version lookups federate to the full repo with kind, space and pin as text-substituted constants. For a registered kind, the member keys are gathered into a single row and the full-repo lookup starts from the kind and shares no variables with them, so it runs once and only touches the kind's own versions. Supersedes RA833rrc, which answered the same but looked up the versions once per member of the space, starting from every nanopublication signed by a member key: several seconds, up to a minute, for spaces whose members have signed many nanopublications. https://w3id.org/np/RAyB49tPLdgMjwmG9alOjtK2wSvxLGPunfncFk57elB-Q/get-latest-governed-version http://purl.org/dc/terms/license http://www.apache.org/licenses/LICENSE-2.0 https://w3id.org/np/RAyB49tPLdgMjwmG9alOjtK2wSvxLGPunfncFk57elB-Q/get-latest-governed-version http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/kpxl/grlc/grlc-query https://w3id.org/np/RAyB49tPLdgMjwmG9alOjtK2wSvxLGPunfncFk57elB-Q/get-latest-governed-version http://www.w3.org/2000/01/rdf-schema#label Get latest governed version https://w3id.org/np/RAyB49tPLdgMjwmG9alOjtK2wSvxLGPunfncFk57elB-Q/get-latest-governed-version https://w3id.org/kpxl/grlc/endpoint https://w3id.org/np/l/nanopub-query-1.1/repo/spaces https://w3id.org/np/RAyB49tPLdgMjwmG9alOjtK2wSvxLGPunfncFk57elB-Q/get-latest-governed-version https://w3id.org/kpxl/grlc/sparql prefix np: <http://www.nanopub.org/nschema#> prefix npa: <http://purl.org/nanopub/admin/> prefix npx: <http://purl.org/nanopub/x/> prefix dct: <http://purl.org/dc/terms/> prefix gen: <https://w3id.org/kpxl/gen/terms/> select distinct ?version ?date ?np ('^' as ?np_label) ?mode where { { # Kind registered for the space: newest version of the (kind, space) pair signed by a current member+. # The member keys are gathered into one row, and the version lookup starts from the kind and shares # no variables with it, so the federated call runs once instead of once per member row. { select (group_concat(distinct ?pubkey;
