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date is read only from the resource's own current defining nanopublication - validly signed, not invalidated and not superseded - rather than from any assertion about it anywhere in the store, so that a third party cannot decide what the form suggests.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/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/get-presentation-defaults http://purl.org/dc/terms/license http://www.apache.org/licenses/LICENSE-2.0 https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/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/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/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/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/get-presentation-defaults https://w3id.org/kpxl/grlc/endpoint https://w3id.org/np/l/nanopub-query-1.1/repo/full https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/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 ; np:hasAssertion ?a ; npx:introduces ?_resource_iri . filter not exists { ?inv npx:invalidates ?np ; npa:hasValidSignatureForPublicKeyHash ?pubkey . } filter not exists { ?newer npx:supersedes ?np . } } optional { graph ?a { ?_resource_iri schemaold:startDate ?sdA . } } optional { graph ?a { ?_resource_iri schema:startDate ?sdB . } } bind(coalesce(?sdA, ?sdB) as ?sd) filter(bound(?sd)) bind(replace(str(?sd), "\.[0-9]+", "") as ?startDate) } limit 1 https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/provenance https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/assertion http://www.w3.org/ns/prov#wasAttributedTo https://orcid.org/0000-0002-1267-0234 https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/pubinfo https://orcid.org/0000-0002-1267-0234 http://xmlns.com/foaf/0.1/name Tobias Kuhn https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk http://purl.org/dc/terms/created 2026-09-08T09:45:44Z https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk http://purl.org/dc/terms/creator https://orcid.org/0000-0002-1267-0234 https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk http://purl.org/dc/terms/license https://creativecommons.org/licenses/by/4.0/ https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk http://purl.org/nanopub/x/embeds https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/get-presentation-defaults https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk http://www.w3.org/2000/01/rdf-schema#label Get the form defaults for a presentation at an event https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk https://w3id.org/np/o/ntemplate/wasCreatedFromProvenanceTemplate https://w3id.org/np/RA7lSq6MuK_TIC6JMSHvLtee3lpLoZDOqLJCLXevnrPoU https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RA-N4_kFxcruvBTlo1yJv29E4SLOXsx5KO_th69PprMrA https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RACJ58Gvyn91LqCKIO9zu1eijDQIeEff28iyDrJgjSJF8 https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RARJj78P72NR5edKOnu_f4ePE9NYYuW2m2pM-fEoobMBk https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk https://w3id.org/np/o/ntemplate/wasCreatedFromTemplate https://w3id.org/np/RAEFAt-QcFK0ZhqfvlsmS10BnzGJA0xwOICZXkO-ai87k https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/sig http://purl.org/nanopub/x/hasAlgorithm RSA https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/sig http://purl.org/nanopub/x/hasPublicKey MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCwUtewGCpT5vIfXYE1bmf/Uqu1ojqnWdYxv+ySO80ul8Gu7m8KoyPAwuvaPj0lvPtHrg000qMmkxzKhYknEjq8v7EerxZNYp5B3/3+5ZpuWOYAs78UnQVjbHSmDdmryr4D4VvvNIiUmd0yxci47dTFUj4DvfHnGd6hVe5+goqdcwIDAQAB https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/sig http://purl.org/nanopub/x/hasSignature Dz/1IN9BgXRmbcWOiKyOV31OrlrlBjtyt10+HaXEVGeB7tl4DlxZDuyCy97xv8HVNRIFwnKwKNzgbER9Fuzys5dAh0Zq4WdVg8M0gZwnhcbvOCB22wg7kEvP8oNDG/H/LTFE2MAe+xKifzllzc/XvVWzRzrq9V7ebdNMOvyoRLg= https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/sig http://purl.org/nanopub/x/hasSignatureTarget https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk https://w3id.org/np/RA5KoJwo5z6Ap1Rzt-n2TkUOWV0CpgNEeaItCNB3g66xk/sig http://purl.org/nanopub/x/signedBy https://orcid.org/0000-0002-1267-0234
