基于语义的Web服务请求和响应模式

Web Services Request and Response Pattern

WSDL作为Web服务的核心技术,使用抽象的术语对服务进行定义,使用具体的数据格式和协议进行实现.但是其对服务的抽象级别比较低,对服务的描述上也不具有表现力,存在着计算机与应用程序在语义上难以互操作的障碍,本文提出了基于语义的Web服务请求和响应模式,并给出了工作模型,对Web服务双方交换的信息内容进行了改进,解决了这一难题.

Web Services has resolved a very difficult problem for interoperability between disparate systems. As a key technology of Web Services, it has defined Web Services by abstract language, and realized them by concrete data formats and protocols, but through WSDL definition ,the Web Services abstract rank is very low and it＇s description to Web Services is not clear. So, the obstacle of interoperability between computers and applications in semantic still exist. In this paper, a pattern of Web Services request and response based on semantic is proposed, at the same time, it＇s working model is provided, This approach has resolved this problem through improving the exchange content between service provider and requester.
