📦 Use the packages

You can easily work with Nanopubs from various languages.

This toolkit will enable you to check, sign, and publish Nanopublications from Rust, Python, and TypeScript/JavaScript.

The core component of this toolkit is written in Rust, with bindings to other languages.

📥️ Installation

Install the package for you language:

PythonJavaScriptRust

pip install nanopub-sign
# or
uv add nanopub-sign

Install the npm package:

npm install --save @nanopub/sign
# or
pnpm add @nanopub/sign
# or
yarn add @nanopub/sign
# or
bun add @nanopub/sign

Or directly import from a CDN in JavaScript code:

import init, { Nanopub, NpProfile, getNpServer } from "https://unpkg.com/@nanopub/sign";

cargo add nanopub

✍️ Sign Nanopubs

This process involves signing a Nanopublication RDF string using a specified RSA private key passed through the profile. The signing operation ensures that the Nanopub is authentically created by the holder of the private key.

Get a private key

You can easily create and register a new private key on the playground page after login with your ORCID.

PythonJavaScriptRust

Build a Nanopublication

This package takes an already prepared Nanopublication RDF string as input. If you want to build a Nanopublication programmatically, use the nanopub pip package. You can then feed the serialized RDF of the built Nanopub to this package functions.

sign.py

from nanopub_sign import Nanopub, NpProfile

Demo

Visit the playground page to sign nanopubs, or generate and register a new key pair, directly in your browser using this NPM package. You can checkout the playground.html file as an example to use the package directly from HTML/JS.

Build a Nanopublication

This package takes an already prepared Nanopublication RDF string as input. If you want to easily display nanopubs checkout the @nanopub/display package, if you want to fetch and manipulate nanopubs check the @nanopub/utils package.

Running in the browser requires initialization

When writing code that will be executed in the browser you need to first initialize the Wasm binary:

import init, { Nanopub, NpProfile, getNpServer } from "@nanopub/sign";

async function main() {
    await init();
    const profile = new NpProfile(privateKey, "https://orcid.org/0000-0000-0000-0000", "Your Name");
    const signed = new Nanopub(rdfStr).sign(profile);
}
main();

📬 Publish Nanopubs

Signed Nanopubs can be published to a Nanopub server. This makes the Nanopub accessible to others in the network.

Use the publish function on a Nanopub, the 2 arguments are optional:

• 🔑 profile is required if you want to also sign the nanopub, it is not required if you provide a signed nanopub
• 🧪 If the server_url is null it will be published to the test server

If the provided server_url is empty or null, the nanopub will be published to the test server. In this case the nanopub will not be available at https://w3id.org/np/, but at https://np.test.knowledgepixels.com/, e.g. https://np.test.knowledgepixels.com/RAKObyGXmbgTYWj2iN0XGgJv0yWNDQd_DTmAWUouGfIsM

To publish to a production server use get_np_server(true). With true for a random server in the network, and false for the main nanopub server, defaults to true.

PythonJavaScriptRust

from nanopub_sign import Nanopub, NpProfile, get_np_server

np = Nanopub(rdf_str).publish(
    profile=profile,
    server_url=None,
    # On production servers:

)
print("Published info dict:", np.info())

Provide the nanopub signed or unsigned

• If signed nanopub and profile not provided, we publish the signed nanopub as it is
• If signed nanopub and profile provided, we re-sign the nanopub (signature triples are updated)
• If unsigned nanopub and profile provided, we sign the nanopub
• If unsigned nanopub and profile not provided, we throw an error

✅ Check Nanopubs

This operation involves checking the integrity of Nanopubs. It ensures that a Nanopub is valid, regardless of whether it is signed or unsigned.

PythonJavaScriptRust

from nanopub_sign import Nanopub

np = Nanopub(rdf_str).check()
print("Checked info dict:", np.info())

import {Nanopub} from "@nanopub/sign";

const checked = new Nanopub(rdfStr).check();

use nanopub::Nanopub;

let checked_np = Nanopub::new(&signed_np.rdf().unwrap()).unwrap().check();

📡 Fetch Nanopubs

This function allows you to retrieve Nanopubs from the network using their URI. It’s useful for accessing and using Nanopubs created by others.

PythonJavaScriptRust

from nanopub_sign import Nanopub

np = Nanopub.fetch("https://w3id.org/np/RAltRkGOtHoj5LcBJZ62AMVOAVc0hnxt45LMaCXgxJ4fw")
print(np.info())

const npUri = "https://w3id.org/np/RAltRkGOtHoj5LcBJZ62AMVOAVc0hnxt45LMaCXgxJ4fw";
const np = await Nanopub.fetch(npUri);
console.log(np.info())

use nanopub::Nanopub;
use tokio::runtime;

let uri = "https://w3id.org/np/RAltRkGOtHoj5LcBJZ62AMVOAVc0hnxt45LMaCXgxJ4fw";
let rt = runtime::Runtime::new().expect("Runtime failed");

let np = rt.block_on(async {
    Nanopub::fetch(&uri).await
}).unwrap();

🔑 Generate private key and publish introduction

You can generate a new private/public key pair, and publish a nanopub introduction to register this key under your ORCID in the Nanopublications network:

PythonJavaScriptRust

from nanopub_sign import Nanopub, NpProfile, KeyPair, get_np_server

# Randomly generate a new private/public key pair
keypair = KeyPair()

# Create a profile with this new private key
new_profile = NpProfile(
    private_key=keypair.private,
    orcid_id="https://orcid.org/0000-0000-0000-0000",
    name="Your Name",
)

# Publish a nanopub introduction for this profile
np = Nanopub.publish_intro(new_profile, get_np_server())
print(np.info())

# Publish to the production network:
# np = Nanopub.publish_intro(new_profile, get_np_server())

import init, {Nanopub, NpProfile, KeyPair} from "@nanopub/sign";

// Randomly generate a new private/public key pair, and convert it to a JS object
let keypair = new KeyPair();
keypair = keypair.toJs();

// Create a profile with this new private key
const orcid = "https://orcid.org/0000-0000-0000-0000"
const profile = new NpProfile(keypair.private, orcid, "Your Name");

// Publish a nanopub introduction for this profile
Nanopub.publish_intro(profile, getNpServer(false))
    .then(np => {
        console.log("Published Introduction Nanopub:", np.info());
    })
    .catch(err => {
        console.error("Error publishing the Nanopub Introduction:", err);
    });

use nanopub::{profile::gen_keys, Nanopub, ProfileBuilder};
use tokio::runtime;

// Randomly generate a new private/public key pair
let (private_key, _pubkey) = gen_keys().unwrap();

// Create a profile with this new private key
let profile = ProfileBuilder::new(private_key)
    .with_orcid("https://orcid.org/0000-0000-0000-0000".to_string())
    .with_name("Your Name".to_string())
    .build()
    .unwrap();

// Publish a nanopub introduction for this profile
let rt = runtime::Runtime::new().expect("Runtime failed");
let np = rt.block_on(async {
    Nanopub::new_intro(&profile).unwrap()
        .publish(Some(&profile), None).await.unwrap();
});

Key format

The key needs to be in format PKCS8, the default OpenSSH format is not supported. Alternatively you can generate a key using the following command:

ssh-keygen -t rsa -m PKCS8 -b 4096 -f ~/.nanopub/id_rsa -C "your@email.com"
