schema.org-type-validator

A type validator for schema.org as a node.js module

Installation

If you're using node.js, install it via npm thusly:

$ npm install schema.org-type-validator

Example Usage

Include the module in your project, and create a Validator:

var schemaTypeValidation = require('schema.org-type-validator');

var validator = new schemaTypeValidation.Validator ();

The Validator uses a Stardog triple store with the schema.org loaded into it. It assumes that you have one running on 127.0.0.1 with a database called 'schema'. You can change this if you need to, like this:

validator.endpoint = 'http://127.0.0.1:5822/';
validator.username = 'admin';
validator.password = 'admin';
validator.database = 'schema';
validator.configureConnection();

Here's what you can do:

Get all the properties of a type:

validator.getProperties('CreativeWork', function (err, result) {
    for (var prop = 0; prop < result.length; prop ++)
        console.log(result[prop]);
});

Get a list of expected types for a property:

validator.getExpectedTypes('aggregateRating', function (err, result) {
    for (var type = 0; type < result.length; type ++)
        console.log(result[type]);
});

Check if a given property is a valid property of a type:

validator.checkIsValidProperty('CreativeWork', 'copyrightHolder', 
    function (err, result) {
        var word = ((result) ? 'is' : 'is not');
        console.log('copyrightHolder ' + word +
            ' a property of CreativeWork');
    }
);

Check if a given type is valid for a property:

validator.checkIsExpectedType('copyrightHolder', 'Place', 
    function (err, result) {
        var word = ((result) ? 'is' : 'is not');
        console.log('Place ' + word +
            ' a valid type for a copyrightHolder');
    }
);
