Returns a single row, or none at all when the resource has no start date, which the form treats as a no-op. The date is read only from the resource's own current defining nanopublication - validly signed, not invalidated and not superseded - rather than from any assertion about it anywhere in the store, so that a third party cannot decide what the form suggests. Both the http:// and https:// schema.org spellings are accepted, Spaces conventionally using the former, and a fractional-second part is trimmed so the default matches the lexical form these events are normally written in. https://w3id.org/np/RA7b5s9_6L7vjbGU81JgZ0bMO3Jcxh7hkEPf0LhxJsgCo/get-presentation-defaults http://purl.org/dc/terms/license http://www.apache.org/licenses/LICENSE-2.0 https://w3id.org/np/RA7b5s9_6L7vjbGU81JgZ0bMO3Jcxh7hkEPf0LhxJsgCo/get-presentation-defaults http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/kpxl/grlc/grlc-query https://w3id.org/np/RA7b5s9_6L7vjbGU81JgZ0bMO3Jcxh7hkEPf0LhxJsgCo/get-presentation-defaults http://www.w3.org/2000/01/rdf-schema#label Get the form defaults for a presentation at an event https://w3id.org/np/RA7b5s9_6L7vjbGU81JgZ0bMO3Jcxh7hkEPf0LhxJsgCo/get-presentation-defaults https://w3id.org/kpxl/grlc/endpoint https://w3id.org/np/l/nanopub-query-1.1/repo/full https://w3id.org/np/RA7b5s9_6L7vjbGU81JgZ0bMO3Jcxh7hkEPf0LhxJsgCo/get-presentation-defaults 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 schema: <https://schema.org/> prefix schemaold: <http://schema.org/> select ?startDate where { graph npa:graph { ?np npa:hasValidSignatureForPublicKeyHash ?pubkey ;
