JSV - A JavaScript implementation of an extendable, fully compliant JSON Schema validator.


A JSON validator is a program that takes JSON data and, with a provided schema, will ensure that the provided JSON is structured in the way defined by the schema. This ensures that if validation has passed, the JSON instance is guaranteed to be in the expected format. It will also provide an explanation on why a particular instance failed validation. There is no one way to validate JSON, just like there is no one way to validate XML. Even the JSON Schema specification has gone through several revisions which are not 100% backwards compatible with each other. To solve the issue of using numerous schemas already written to older specifications, JSV provides customizable environments to validate your JSON within.
