## Overview for Gravey Framework and RATS RIA.

The Gravey (aka Gravy 2.0) framework is a set of Javascript include files that implement model-view-controller support classes. The framework home page is at GRAVEY.ORG. The RATS RIA is a Gravey demonstration application.

This library supports Rich Internet Application (RIA) code in the browser using the Model-View-Controller design pattern supported by Observer, Command, Bean, Composite, etc. design patterns.

The AJAX classes supports asynchronous REST-style web service requests for XML data that is transformed into Javascript data via XSL and is all executed in the browser. The server merely accepts REST-style requests for data CRUD operations.

The RATS (Reconcile Account Transactions System) demonstration Single Page Application is built upon these libraries, defining Command objects, Models, Views, Controllers, event handlers, and AJAX requests.

NOTE: Portions of this framework and sample application require Internet Explorer 5.0 or greater.
