Create a Nanopublication

Prerequisite for creating/publishing

To create and publish nanopublications, you need to first make sure you have a local keypair. To create such a keypair, run just once:

MakeKeys.make("~/.nanopub/id", SignatureAlgorithm.RSA);

NanopubCreator npCreator = new NanopubCreator(true);
final ValueFactory vf = SimpleValueFactory.getInstance();
final IRI anne = vf.createIRI("https://example.com/anne");
npCreator.addAssertionStatement(anne, RDF.TYPE, vf.createIRI("https://schema.org/Person"));
npCreator.addProvenanceStatement(PROV.WAS_ATTRIBUTED_TO, anne);
npCreator.addPubinfoStatement(RDF.TYPE, vf.createIRI("http://purl.org/nanopub/x/ExampleNanopub"));
Nanopub np = npCreator.finalizeNanopub(true);

Sign a Nanopublication

Prerequisite for signing/publishing

Before you can sign and publish you should setup your profile, check if it is properly set by running np profile in your terminal.

Nanopub signedNp = SignNanopub.signAndTransform(np, TransformContext.makeDefault());

Publish a Nanopublication

Prerequisite for creating/publishing

To create and publish nanopublications, you need to first make sure you have a local keypair. To create such a keypair, run just once:

MakeKeys.make("~/.nanopub/id", SignatureAlgorithm.RSA);

Publish to the Test Server

PublishNanopub.publishToTestServer(signedNp);

Publish to the Production Server

PublishNanopub.publish(signedNp);
