rdf-validation is a modular library to validate RDF data provided as RDF/JS objects.
Different modules can be combined to tailor a validation according to personal needs.
npm install --save rdf-validationThe package exports multiple validations.
All validations are classes, and it requires creating instances for them.
A validation object has a .validate() and a .validateSimple() method.
.validate() returns a Report with results for different checks and includes a message.
.validateSimple() is an optimized method that returns only true if the given object is valid and false in case it is not.
See the following example on how to check if quads match the RDF Model and literal values are valid according to the XSD specification:
import rdf from 'rdf-ext'
import { RdfModelValidation, XsdValidation } from '../index.js'
const rdfModelValidation = new RdfModelValidation({ factory: rdf })
const xsdValidation = new XsdValidation({ factory: rdf })
const quad = rdf.quad(
rdf.literal('resource'),
rdf.namedNode('https://example.org/date'),
rdf.literal('1.1.2001', rdf.namedNode('http://www.w3.org/2001/XMLSchema#date'))
)
const rdfReport = rdfModelValidation.validate(quad)
console.log(`conforms: ${rdfReport.conforms}`)
console.log(`message: ${rdfReport.results[0].message[0]}`)
console.log(`validateSimple: ${rdfModelValidation.validateSimple(quad)}`)
const xsdReport = xsdValidation.validate(quad.object)
console.log(`conforms: ${xsdReport.conforms}`)
console.log(`message: ${xsdReport.results[0].message[0]}`)
console.log(`validateSimple: ${xsdValidation.validateSimple(quad.object)}`)See the examples folder for more examples.
