In the rapid development of the Internet today,some technologies came into being,such as HTML5,WEB2.0 technologies.These technologies enable the emergence of Web App.Web App does not need to download and install,and is a kind of application in the browser.Although the use of Web App light application is very convenient,there are still a lot of duplication of work and technical details in the development.And the development of lightweight software should focus on the realization of specific functions,the user's ease of use and experience of the design.To solve the repetitive work is to inject the Model Driven Architecture (MDA) into the Web App development,and to change the development of the work from the code as the core to the model as the core.In this paper,a MDA based Web App is used to develop a framework MDWAF (Model Driven App develop Framework).This paper presents an improved method of establishing a platform independent model in MDWAF.%在互联网飞速发展的今天,一些技术应运而生,如HTML5,WEB2.0技术.这些技术使得Web App得以出现.Web App不需要下载安装,是一种生存于浏览器中的应用.虽然Web App这种轻应用使用起来很方便,但开发过程中仍有大量的重复的工作与技术细节,而且轻型软件的开发应该着重具体功能的实现、用户的易用性和体验度的设计上.解决重复性工作就是将模型驱动架构(Model Driven Architecture,MDA)注入到Web App开发中,将开发工作从以代码为核心转变为以模型为核心.本文借助了一个基于MDA的Web App开发框架MDWAF(Model Driven Web App develop Framework)[1],提出了MDWAF中的平台无关模型的建立过程的改进方法.
