摘要
In order to fully realize semantic interoperability among distributed and heterogeneous applications on the web, a set of effective interoperability mechanisms is presented. This mechanism adopts service interactive interfaces （SII） and service aggregative interfaces （SAI） modeled with abstract state machine （ASM） to abstractly describe the behavior of the invoked web service instances, which makes business processing accurately specify tasks and effectively solves the problems of communication and collaboration between service providers and service requesters. The mechanism also uses appropriate mediators to solve the problems of information and coinmunication incompatibility during the course of service interaction, which is convenient for service interoperability, sharing and integration. The mechanism＇ s working principle and interoperability implementation are illustrated by a use case in detail.
为了真正实现web上异构、分布的应用程序间的语义互操作,提出了一套有效的互操作机制.该机制用抽象状态机模型化的服务交互接口和服务聚集接口来抽象化描述被调用的web服务实例的行为,使业务处理能够准确地进行任务指派,有效解决了服务双方的通讯和协作问题;给出适当的调解技术解决交互过程中的通讯和信息的不兼容问题,便于服务间的互操作、共享和集成.通过一应用实例对该机制的工作机理和互操作实现进行了详尽的阐述.
