Events are Spaces typed as gen:Event, and the organizer relation is a role instantiation published as a separate nanopublication, so this query joins the two and checks that both carry a valid signature. It runs against the full repository because the event definition and the role grant land in different type-specific repositories. https://w3id.org/np/RAIEWBhPg4db5fEo5rIf5NOuJLx1PSoEQcrxWN-jChgJ0/get-events-organized-by http://purl.org/dc/terms/license http://www.apache.org/licenses/LICENSE-2.0 https://w3id.org/np/RAIEWBhPg4db5fEo5rIf5NOuJLx1PSoEQcrxWN-jChgJ0/get-events-organized-by http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/kpxl/grlc/grlc-query https://w3id.org/np/RAIEWBhPg4db5fEo5rIf5NOuJLx1PSoEQcrxWN-jChgJ0/get-events-organized-by http://www.w3.org/2000/01/rdf-schema#label Get events organized by person https://w3id.org/np/RAIEWBhPg4db5fEo5rIf5NOuJLx1PSoEQcrxWN-jChgJ0/get-events-organized-by https://w3id.org/kpxl/grlc/endpoint https://w3id.org/np/l/nanopub-query-1.1/repo/full https://w3id.org/np/RAIEWBhPg4db5fEo5rIf5NOuJLx1PSoEQcrxWN-jChgJ0/get-events-organized-by 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 owl: <http://www.w3.org/2002/07/owl#> prefix gen: <https://w3id.org/kpxl/gen/terms/> prefix schema: <http://schema.org/> select ?event ?event_label ?description ?startDate ?endDate ?location ?location_label (min(?website) as ?website) ?np ("^" as ?np_label) where { # the nanopublication that defines the event graph npa:graph { ?np npa:hasValidSignatureForPublicKeyHash ?pubkey . filter not exists { ?npx npx:invalidates ?np ; npa:hasValidSignatureForPublicKeyHash ?pubkey . } filter not exists { ?np npx:hasNanopubType npx:ExampleNanopub . } ?np np:hasAssertion ?a . ?np np:hasPublicationInfo ?pi . ?np npx:introduces ?event . } graph ?a { ?event a gen:Event ; rdfs:label ?event_label . optional { ?event dct:description ?description . } optional { ?event schema:startDate ?startDate . } optional { ?event schema:endDate ?endDate . } optional { ?event schema:location ?location . } optional { ?event owl:sameAs ?website . } } # The organizer role is granted by a separate nanopublication.
