XAP - eXtensible Ajax Platform

A project proposal from Apache …

XAP is to provide an XML-based declarative framework for building, deploying and maintaining rich, interactive, Ajax-powered web applications. A basic principal of XAP is to leverage existing Ajax projects such as Apache Kabuki and Dojo, as well as other community efforts such as Eclipse openAjax. It aims to be pluggable with various Ajax toolkits, reduce the need of scripting and solve the development challenge as well as application maintenance challenges associated with Ajax programming.
