面向过程的Mashups教学资源聚合模型研究

Process Modeling in Process-Oriented Teaching Mashups

为了降低教学资源的Mashups应用设计门槛!让一线教师(可能是不懂计算机技术的)也能够设计出适合自己的教学业务系统,本文提出将SOA、Web 2.0技术和Web服务集成到面向服务的教学业务应用上,以实现Mashups教学资源聚合模型。根据Mashups教学资源聚合模型的建模需求和原则,选择有效的建模符号(BPMN子集)及控制流模式(Processpatterns)!将其作为基础集扩展过程模版(Process templates)和过程片断(Process fragments),提出了一个轻量级教学资源聚合模型。通过构造一个教学资源(服务)聚合平台,为一线教师亲自构建个性化教学系统做出有效示范。如何丰富扩展建模语言和实现具有嵌有Web服务的引擎机制是未来研究方向。

It is very valuable at present that integrating SOA, Web 2.0 technologies and Web services into a service-oriented appli- cation connects teaching process. In this paper we explore about teaching-resource （services） Mashups, focus on constructing of process modeling in process-oriented teaching Mashups, so as to provide an environment for popular teachers, which teachers （in cluding non-technologic teachers） can design and implement a personalized teaching system by themselves using the process model- ing in process-oriented teaching Mashups. In this paper we discuss the demand and principle about modeling in process oriented teaching Mashups, go further in depth on lightweight teaching modeling, including choosing modeling symbol （BPMN subset）, control flow （Process patterns）, and extending a set of process templates and process fragments. A scenario was given to play a demonstration role in personalized teaching. Further efforts such as how to enrich extended modeling language and implement the engine of Web service are needed, before we are able to easily connect existing web resources for implementing process oriented teaching Mashups.
