zazukoZazuko's RDF/JS Environment
Like rdf-ext, with some additional features.
import env from '@zazuko/env'
// bind namespace to create named nodes
const tbbt = env.namespace('https://tbbt.tv/')
// use clownface for easy graph manipulation
const sheldonCooper = env.clownface()
.namedNode(tbbt.sheldon)
// use common vocabularies out-of-the box
.addOut(env.ns.rdf.type, env.ns.schema.Person)
.addOut(env.ns.schema.knows, tbbt.leonard)Browser usage
The main export includes rdf-dataset-ext package to extend the dataset's functionality.
This package may cause issues in the browser, so you can import @zazuko/env/web.js instead.
Additional features
Dataset
Static util functions
The dataset factory implemented by the main module environment provides some static utility functions from the rdf-dataset-ext package.
import { Stream, DatasetCore } from '@rdfjs/types'
import env from '@zazuko/env'
let stream: Stream
// shorthand for creating a dataset from a stream
const dataset: DatasetCore = await env.dataset.fromStream(stream)
// stream any DatasetCore
const streamFromCoreDataset: Stream = env.dataset.toStream(dataset)
// convert any DatasetCore to a canonical form
const canonicalQuads = env.dataset.toCanonical(dataset)rdf-ext functionality
The provided DatasetCore implementation provides additional methods, matching the rdf-ext interface.
Serializing
It also includes a serialize method to easily get a string representation for supported formats.
Serializers are not added out of the box and the need to be imported first
import rdf from '@zazuko/env'
import formats from '@rdfjs/formats'
rdf.formats.import(formats)
const dataset = rdf.dataset()
// create some data
const turtle = await dataset.serialize({ format: 'text/turtle' })Extending environments
This package adds the ability to create environments on top of existing ones. To do that, pass the parent environment to the constructor options.
import env from '@zazuko/env';
import Environment from '@zazuko/env/Environment.js';
import MyFactory from './my-factory.js';
const myEnv = new Environment([MyFactory], { parent: env });The myEnv will have all the factories from env and MyFactory.
