大数据环境下,跨组织平台工作流业务间的协同与调度,异构系统应用之间的数据共享与交互操作是服务计算动态交换技术亟待解决的问题.结合泳道技术与WS-BPEL流程组合规范,通过模型驱动和原子化服务调用算法表达动态服务交互操作,研究跨组织平台协同服务计算互操作规范工作流结构.构建了该结构的协同服务计算互操作支撑模型,详细阐述了该支撑模型中的任务分解机制、互操作服务传递机制及引擎协同执行机制.实验分析表明,该协同服务计算工作流互操作能力能适应大数据环境下多样性、动态性及个性化特征.通过实例将该系统模型应用于高校数字基座应用服务,实现了教育数字化应用服务的动态互操作,助力教育数字基座规范建设.

In the Big data environment,the collaboration and scheduling between workflow businesses across organizational platforms,and the data sharing and interactive operation between heterogeneous system applications are the problems that need to be solved urgently in the dynamic exchange technology of service computing.Combining swim lane technology with the process combination specification of WS-BPEL,dynamic service interaction operations are expressed through model-driven and atomic service invocation algorithms,and the workflow structure of cross-organizational platform collaborative service computing interoperability specifications is studied.The structure of the interoperability support model for collaborative service computing has been constructed,and the task decomposition mechanism,interoperability service delivery mechanism,and engine collaborative execution mechanism in this support model have been elaborated in detail.The experimental analysis of the model shows that the interoperability of the collaborative service computing workflow can adapt to the diversity,dynamic and personalized characteristics in the Big data environment.By applying this system model to digital base application services through examples in universities,it can solve the dynamic interoperability of educational digital application services and help the standardized construction of the education digital base.
