Itemscript is a project to build a set of open-source tools for working with JSON, both in server-side Java environments and client-side GWT/browser environments.

The Itemscript JSON library is a JSON library for both standard Java environments and the GWT Java environment. It's released under the new BSD license.
Itemscript Schema is a draft specification for a simple schema language for JSON. The goal is to be useful for any kind of JSON application as well as for Itemscript applications.
