●SOAP Version l.2(SOAP)is a lightweight(1)intended for exchanging structured information in a decentralized。distributed environment.It uses(2)technologies to define an extensible messaging framework providing a message construct that can be exchanged over a variety of underlying protocols· The framework has been designed to be(3)of any particular programming model and other implementa— tion sDecifie semantics.Two major design goals for SOAP are(4)and(5).SOAP attempts to meet these， goals by omitting，from the messaging framework，features that are often found in distributed sys-terns.

　　解析：SOAP簡單對象應用協(xié)議是一個輕量級的協(xié)議，它的目的是在分散和分布的環(huán)境下交換結構化的信息。它使用XML技術來定義一個可擴展的消息框架以提供一個可在各種底層協(xié)議上交互的消息架構。這個消息框架被設計成為獨立于任何編程模型和其他具體實現(xiàn)語義。SOAP設計的兩大主要目的是簡單和可擴展。SOAP試圖通過在消息框架上省略分布式系統(tǒng)中常見的特征來達到這兩個目的。
