An observed event is a space typed as an event (gen:Event) in which the user holds the observer role, i.e. a validated role instantiation whose property is gen:hasObserver in the current space state. The user does not need any other role in the event, and holding one (such as admin) does not exclude it. Other roles of the observer tier, such as planned attendance or participation, are not matched. An event counts as current or future while its end date (or its start date, when it has no end date) is today or later, so an event under way is still listed until its last day has passed; events without a start date are left out, since they cannot be placed in time. Each event is described from the newest still-valid nanopublication that introduces it, giving its label and its dates (a single day, or a start - end range), ordered by start date, soonest first. https://w3id.org/np/RAlZD5yYrf1Q5i-LB5jAcIzQ_1wLrXSa4E2dq7kS9yylI/get-observed-events-of-user http://purl.org/dc/terms/license http://www.apache.org/licenses/LICENSE-2.0 https://w3id.org/np/RAlZD5yYrf1Q5i-LB5jAcIzQ_1wLrXSa4E2dq7kS9yylI/get-observed-events-of-user http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/kpxl/grlc/grlc-query https://w3id.org/np/RAlZD5yYrf1Q5i-LB5jAcIzQ_1wLrXSa4E2dq7kS9yylI/get-observed-events-of-user http://www.w3.org/2000/01/rdf-schema#label Get events a user is interested in https://w3id.org/np/RAlZD5yYrf1Q5i-LB5jAcIzQ_1wLrXSa4E2dq7kS9yylI/get-observed-events-of-user https://w3id.org/kpxl/grlc/endpoint https://w3id.org/np/l/nanopub-query-1.1/repo/type/8ad572d99071cc1ba0c16e54087b43594bdd9e8b2cfb62d2a0b16945fc49e53c https://w3id.org/np/RAlZD5yYrf1Q5i-LB5jAcIzQ_1wLrXSa4E2dq7kS9yylI/get-observed-events-of-user 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/> prefix xsd: <http://www.w3.org/2001/XMLSchema#> select ?event ?event_label ?dates ?np ("^" as ?np_label) where { { select distinct ?event where { service <https://w3id.org/np/l/nanopub-query-1.1/repo/spaces> { graph npa:graph { npa:thisRepo npa:hasCurrentSpaceState ?stateG . } graph ?stateG { ?ri a gen:RoleInstantiation ;
