Wsci uses a transaction element to model the behavior of a web service and treats a number of activities as a single unit of work Wsci使用事务元素为web服务行为建模，并且将一组行为作为一个工作单元。
Wsci can raise an exception based on a fault message from wsdl , a message content , or an event for example , timeout event Wsci能抛出一些异常，它们来自于wsdl 、信息内容或事件（例如，超时事件）的错误信息。
Exceptions are a wsci modeling artifact designed to model the exceptional behavior exhibited by a web service , at a given point of a conversation 异常是wsci的建模能力，其设计的目的是为在web服务编排的断点中显示的行为建模。
Thus , wsci supports the concept of " recoverable exceptions " that do not cause the overall choreography to terminate similar to the throw catch concept in java 所以， wsci支持“恢复异常”的概念，它不会导致整个系统重排而停止（和java中try / catch的概念相似） 。
10 may 2005 find out how you can use the web service choreography interface wsci to weave different web services into meaningful business processes 通过本文，您能学会如何使用web服务编排接口（ wsci ）将不同的web服务编排在一起，并应用到具有实际意义的业务流程中。
A web service uses a wsci transaction to communicate to other services its ability to either completely execute those activities or to restore to a consistent state prior to the execution Web服务使用wsci事务与其它服务通信，它要么完全执行完这些活动，要么将其存恢复到执行之前的一致状态。
But i ve only scratched the surface . in order to understand more about wsci , you might want to read the wsci specification and write a simple example application using wsci 但是我只揭开了它的表面的部分，为了更深入地了解wsci ，您也许想看看wsci规范，并且使用wsci来编写些简单的应用程序样例。
There are other specifications such as sun s web services choreography interface wsci , intalio s business process markup language bpml and ebxml s business process schema specification bpss 其它规格还有sun的网络服务编排界面wsci intalio的业务程序标示语言bpml及ebxml的业务程序模式规格bpss 。
