●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(jiǎn)單對(duì)象應(yīng)用協(xié)議是一個(gè)輕量級(jí)的協(xié)議，它的目的是在分散和分布的環(huán)境下交換結(jié)構(gòu)化的信息。它使用XML技術(shù)來(lái)定義一個(gè)可擴(kuò)展的消息框架以提供一個(gè)可在各種底層協(xié)議上交互的消息架構(gòu)。這個(gè)消息框架被設(shè)計(jì)成為獨(dú)立于任何編程模型和其他具體實(shí)現(xiàn)語(yǔ)義。SOAP設(shè)計(jì)的兩大主要目的是簡(jiǎn)單和可擴(kuò)展。SOAP試圖通過(guò)在消息框架上省略分布式系統(tǒng)中常見(jiàn)的特征來(lái)達(dá)到這兩個(gè)目的。
