JSON schema validation

The JSON schema validator [https://github.com/fge/json-schema-validator] enables a JSON object to be validated against a corresponding schema. The library promises the following:
 - JSON Syntax validation and instance validation
 - Extensive schema loading customisation
 - No dependencies
 - Immutable processors
 - Thread safety

An online site is provided for testing the library at [http://json-schema-validator.herokuapp.com/]. The site allows validation of JSON instances by pasting the schema and data in the appropriate text areas and pressing the validate button.
