Every nanopublication has a globally unique, content-based Trusty URI, made persistently resolvable through w3id.org (for example, https://w3id.org/np/RA...). This URI is the canonical citation: it permanently identifies the exact, immutable content of the nanopublication, can be verified by anyone who retrieves it, and resolves to a viewable rendering. When listing a nanopublication in a reference list, treat the trusty URI as the URL and use the metadata from the publication info for the rest: dct:creator (typically an ORCID) for the author, rdfs:label for the title, and dct:created for the date. Because the trusty URI is immutable, no version, hash, or access date is needed — even if the nanopublication is later superseded or retracted, the citation still points unambiguously at the original version. For example, the nanopublication at https://w3id.org/np/RAiBSheuO17iqJacTs9aSeK3k80vf4BswE5BNQ-UR9MG0 could be cited as:

Kuhn, T. (2026). Night train to Vienna [nanopublication]. https://w3id.org/np/RAiBSheuO17iqJacTs9aSeK3k80vf4BswE5BNQ-UR9MG0
