+This project is an implementation of the [JSON Schema Core Draft v4][draft-zyp-json-schema-04] specification.
 It uses the [org.json API](http://stleary.github.io/JSON-java/) (created by Douglas Crockford) for representing JSON data.
 
 # When to use this library?
 
 Lets assume that you already know what JSON Schema is, and you want to utilize it in a Java application to validate JSON data.

  * if you want to use anything else for handling JSON (like GSON or javax.json), then you are in a little trouble, since
 currently there is no schema validation library backed by these libraries. It means that you will have to parse the JSON
 twice: once for the schema validator, and once for your own processing. In a case like that, this library is probably still
