一种基于DSL的服务组合语言

摘要

针对大规模并发应用在组合服务中的服务调度问题,设计一种基于领域专用语言的服务组合语言,给出该语言的主要功能、构造过程和语言执行引擎的详细设计.该语言提供对Web服务组合过程的语义和语法描述,采用自顶向下的组合方式,能解决Web服务组合过程中的组合粒度控制和异构消息匹配等问题.%This paper designs a service composition language based on Domain Specific Language(DSL) for the service scheduling problem in the large-scale concurrent applications. It gives the main features, constructing process and the executing engine's detailed design of the language. The language provides the semantic description and syntax description of the composition process for Web services. It uses top-down composition approach to solve the composition process granularity control and heterogeneous messages matching.
