This makes the link between identifier and content permanent and verifiable — given a nanopublication and its identifier, anyone can check that the content has not been changed, and a given identifier can never end up pointing to different content. Nanopublications are therefore immutable: corrections are published as new nanopublications with new identifiers, linked to the old version rather than replacing it in place.</p> <p>Resolution of the identifiers does not depend on a single server. The <code>https://w3id.org/np/</code> identifiers are persistent redirects run by the <a href="https://w3id.org/">w3id.org</a> initiative, backed by a community commitment to keep them stable, and they can be redirected to whatever services are current. Behind them, the nanopublication network consists of multiple independent registry servers that each hold full copies of the published nanopublications, so no single party can lose or withhold them. Since the identifier itself verifies the content, a nanopublication retrieved from <em>any</em> source — a registry, a mirror, or a local archive — can be trusted to be authentic.</p> https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I/provenance https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I/assertion http://www.w3.org/ns/prov#wasAttributedTo https://orcid.org/0000-0002-1267-0234 https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I/pubinfo https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I http://purl.org/dc/terms/created 2026-07-16T11:40:38Z https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I http://purl.org/dc/terms/creator https://orcid.org/0000-0002-1267-0234 https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I http://purl.org/dc/terms/license https://creativecommons.org/licenses/by/4.0/ https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I http://purl.org/nanopub/x/hasNanopubType http://schema.org/Question https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I http://purl.org/nanopub/x/introduces https://w3id.org/np/RAOP1DBuhXoCJV8bodEbcVUBL1rSVMxX2wAmjDwvIFqI8/faq-entry https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I http://purl.org/nanopub/x/supersedes https://w3id.org/np/RAHgwBEQ5aibxAvNuKVebMlfv_QD1y1KHhoaHXGSQAbvg https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I http://www.w3.org/2000/01/rdf-schema#label FAQ: What measures have been taken towards long-term stability of the nanopublication identifiers? https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I https://w3id.org/np/o/ntemplate/wasCreatedFromProvenanceTemplate https://w3id.org/np/RA7lSq6MuK_TIC6JMSHvLtee3lpLoZDOqLJCLXevnrPoU https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RACJ58Gvyn91LqCKIO9zu1eijDQIeEff28iyDrJgjSJF8 https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RAoTD7udB2KtUuOuAe74tJi1t3VzK0DyWS7rYVAq1GRvw https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RAukAcWHRDlkqxk7H2XNSegc1WnHI569INvNr-xdptDGI https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I https://w3id.org/np/o/ntemplate/wasCreatedFromTemplate https://w3id.org/np/RAUneCxaT_JQhs4XK8yFhSm5JGmAMgn8k6zBkWB2pp3BI https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I/sig http://purl.org/nanopub/x/hasAlgorithm RSA https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I/sig http://purl.org/nanopub/x/hasPublicKey MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCwUtewGCpT5vIfXYE1bmf/Uqu1ojqnWdYxv+ySO80ul8Gu7m8KoyPAwuvaPj0lvPtHrg000qMmkxzKhYknEjq8v7EerxZNYp5B3/3+5ZpuWOYAs78UnQVjbHSmDdmryr4D4VvvNIiUmd0yxci47dTFUj4DvfHnGd6hVe5+goqdcwIDAQAB https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I/sig http://purl.org/nanopub/x/hasSignature fMkadseikZMiy75We98Bgr2EhkQCNfrkP0by7U6CiNRQeFloBPC4mi1PT8u70AfLkx9QvO8S7xAFI+w2mC61Gv/1C3wLGgMGCNP0yyzRkRpmwUCC6T/NzNqurvscXEk/KcBdx0n2KXniC9z2DUAyBijr/MvwV7oXwtzElgkpChs= https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I/sig http://purl.org/nanopub/x/hasSignatureTarget https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I https://w3id.org/np/RAd-YDlxr49H5AnLn7Q7fcq5tHeHrE-FHS2fS6ZWzVl3I/sig http://purl.org/nanopub/x/signedBy https://orcid.org/0000-0002-1267-0234
