    ns4:hasContent """<p>The nanopublication ecosystem is built entirely on standard <a href=\"https://www.w3.org/RDF/\">RDF</a> and Semantic Web technologies. Each nanopublication is an RDF dataset of four <a href=\"https://www.w3.org/TR/rdf11-concepts/#section-dataset\">named graphs</a>, typically serialized as <a href=\"https://www.w3.org/TR/trig/\">TriG</a>. Identifiers are <a href=\"https://trustyuri.net/\">Trusty URIs</a> — content-based hashes that make every nanopublication immutable and self-verifying — and integrity and authorship are protected by RSA digital signatures recorded in the publication info. In practice, Trusty URIs are commonly made persistently resolvable through <a href=\"https://w3id.org/\">w3id.org</a>, and authors are commonly identified by <a href=\"https://orcid.org/\">ORCID</a>, but neither is a technical requirement of the format.

At the network level, the <a href=\"https://github.com/knowledgepixels/nanopub-registry\">Nanopub Registry</a> stores and serves nanopublications through an HTTP REST interface, while <a href=\"https://github.com/knowledgepixels/nanopub-query\">Nanopub Query</a> provides <a href=\"https://www.w3.org/TR/sparql11-query/\">SPARQL</a> endpoints and additionally exposes published SPARQL templates as REST APIs. Reference libraries are available in Java, Python, and Rust, and user-facing tools such as <a href=\"https://github.com/knowledgepixels/nanodash\">Nanodash</a> are built on top of these.</p>""" .
