RDF Check Mate

Validation and documentation generation for JSON-LD schemas (in the schema.org fashion).

Currently very naive proof of concept.

Setup:

Install using yarn (needed for postinstall script/retrieval) yarn

Use

Valid:

// Checking against Book schema from schema.org
import { Book } from 'schema-doter';

const sampleObject = {
    'numberOfPages' : 4,
    'title'         : 'Dave',
    'author'        : 'me',
    'published'     : 'now',
    'publisher'     : 'yes '
};

valid = validate( Book, {...sampleObject, numberOfPages: 4.2222} );

// This warns in console:
//
// There is some incompatability between your provided object and the schema...
//  title , published do not exist on this schema

// But:
console.log( valid ) // true

Invalid:

const badObject = {
    'numberOfPages' : 4.1,
    'title'         : 'Dave',
    'author'        : 'me',
    'published'     : 'now',
    'publisher'     : 'yes '
};

valid = validate( Book, {...badObject, numberOfPages: 4.2222} );
console.log( valid ) // false

// also throws:
// Candidate data type error: 4.1 is number should be: Integer

TODO

• Publish as npm package?
  • Setup main script / build / etc
• Add tests
• use RDFlib for extracting props etc.
• setup CI
• Add validity checks for more data types and classes etc
