【摘要】 从基于WSDL的服务接口描述语言入手,分析了Web服务组合的类型和消息依赖关系。将服务组合分为顺序组合、替换组合、混合式组合三种类型;结合这些类型,将组合服务中的消息依赖定义为消息映射依赖、消息合成依赖和消息分解依赖三种关系。在此基础上,提出了一种轻量级的组合服务描述语言(CWSDL)。更多还原

【Abstract】 Starting from service interface description language based on WSDL,the types of Web services composition and the relationships between message dependencies are analyzed.Web services composition is categorized into three types: sequential,substituted and hybrid composition.By considering the types of composition,three kinds of message dependencies are defined: message mapping,message composing and message decomposing.Based on these,a kind of lightweight composite Web services description language(CWSDL) is proposed.更多还原
