Grails vs. GraPHP vs. Atmosphere

Grails is a framework used to build web applications with the Groovy programming language. The core framework is very extensible and there are numerous plugins available that provide easy integration of add-on features.

The goal of this project is to build a lightweight web framework with a graph DB abstraction. It should be very easy to create the graph schema with no knowledge of of how the data is stored. Also, the schema should be incredibly flexible so you should never need migrations when adding new models (nodes), connections (edges), or data that lives in nodes.

The Atmosphere Framework contains client and server side components for building Asynchronous Web Applications. The majority of popular frameworks are either supporting Atmosphere or supported natively by the framework. The Atmosphere Framework supports all major Browsers and Servers.
