例如，是否有必要通过类似于代理的中间件系统来把客户端身份传递到服务实现的最终提供者？

For example, is there a need to propagate client identity through intermediate systems such as brokers to the end-providers of service implementations?

同时，目标发起者或代理之间的协议集中于三个软目标变量(举例而言)，系统分析人员可以将这些变量转换为可实现的需求。

At the same time, the goal originator or an agreement between the agents focuses on, say, three soft goal variables that the analysts can turn into implementable requirements.

最后，当某个参与者代表系统中的另一个参与者执行操作时，我们就称它为代理。

And, finally, an actor is called a facilitator when it performs an action on behalf of another actor in a system.
