It returns the nanopublication's creation date if the nanopublication is present, and an empty result otherwise. It is designed to be as cheap as possible (a single indexed lookup), so it can be used to poll for the arrival of a just-published nanopublication, for example to delay a cache refresh until the new nanopublication has made its round trip through the network. https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/check-nanopub-loaded http://purl.org/dc/terms/license http://www.apache.org/licenses/LICENSE-2.0 https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/check-nanopub-loaded http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/kpxl/grlc/grlc-query https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/check-nanopub-loaded http://www.w3.org/2000/01/rdf-schema#label Check if a nanopublication is loaded https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/check-nanopub-loaded https://w3id.org/kpxl/grlc/endpoint https://w3id.org/np/l/nanopub-query-1.1/repo/meta https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/check-nanopub-loaded https://w3id.org/kpxl/grlc/sparql prefix npa: <http://purl.org/nanopub/admin/> prefix dct: <http://purl.org/dc/terms/> select ?date where { graph npa:graph { ?_np_iri dct:created ?date . } } limit 1 https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/provenance https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/assertion http://www.w3.org/ns/prov#wasAttributedTo https://orcid.org/0000-0002-1267-0234 https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/pubinfo https://orcid.org/0000-0002-1267-0234 http://xmlns.com/foaf/0.1/name Tobias Kuhn https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos http://purl.org/dc/terms/created 2026-08-25T12:12:53Z https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos http://purl.org/dc/terms/creator https://orcid.org/0000-0002-1267-0234 https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos http://purl.org/dc/terms/license https://creativecommons.org/licenses/by/4.0/ https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos http://purl.org/nanopub/x/embeds https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/check-nanopub-loaded https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos http://www.w3.org/2000/01/rdf-schema#label Check if a nanopublication is loaded https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos https://w3id.org/np/o/ntemplate/wasCreatedFromProvenanceTemplate https://w3id.org/np/RA7lSq6MuK_TIC6JMSHvLtee3lpLoZDOqLJCLXevnrPoU https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RA0J4vUn_dekg-U1kK3AOEt02p9mT2WO03uGxLDec1jLw https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos https://w3id.org/np/o/ntemplate/wasCreatedFromTemplate https://w3id.org/np/RAEFAt-QcFK0ZhqfvlsmS10BnzGJA0xwOICZXkO-ai87k https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/sig http://purl.org/nanopub/x/hasAlgorithm RSA https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/sig http://purl.org/nanopub/x/hasPublicKey MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCwUtewGCpT5vIfXYE1bmf/Uqu1ojqnWdYxv+ySO80ul8Gu7m8KoyPAwuvaPj0lvPtHrg000qMmkxzKhYknEjq8v7EerxZNYp5B3/3+5ZpuWOYAs78UnQVjbHSmDdmryr4D4VvvNIiUmd0yxci47dTFUj4DvfHnGd6hVe5+goqdcwIDAQAB https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/sig http://purl.org/nanopub/x/hasSignature aYdvoTH1Gw+Qz4BDdSs8GGhgR7umoBdFNzNpqHqBBeA2TOD+52P3ACi5zujqiMpmGODggR6jylb9r2VDjMF8Ra97taxTdS9EG6QtoxH110MhiWZYFo3KK4KRCxi/aB8YTeDVqqHcQZn9Pcc6BjOeAqM4eP3+QJYxOVfN227B/TA= https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/sig http://purl.org/nanopub/x/hasSignatureTarget https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos https://w3id.org/np/RAxqXyhP1fnjvDdX-K0z9TgnwoXf462FxV1wEAWRm_gos/sig http://purl.org/nanopub/x/signedBy https://orcid.org/0000-0002-1267-0234
