2
3const buffer = fetchFileOrUrl('/path/or/url/to/file');

namespaces

Function that ensures that we don't have to write full URIs anymore. Takes the local identifier as string parameter and returns an RDF.NamedNode:

import { ns } from '@oslo-flanders/core'

const exampleNamedNode = ns.example('test');

// exampleNamedNode.value is equal to 'http://example.org/test'

const rdfType = ns.rdf('type');

// rdfType.value will be 'http://www.w3.org/1999/02/22-rdf-syntax-ns#type'

uniqueId

Function that returns random string, with a very low probability that the same string is going to be returned multiple times.

import { uniqueId } from '@oslo-flanders/core'

const id = uniqueId();
