引述 :『The SOA with reach: Web-Oriented Architecture』

引述 :『Service-oriented architecture (SOA) is an architectural style that is modular, distributable, shareable and loosely coupled. When applying SOA concepts to the Web, a new architectural style, Web-oriented architecture (WOA), comes into play. WOA is a substyle of SOA based on the architecture of the Web with additional constraints: globally linked, decentralized and uniform intermediary processing of application state via self-describing messages. Essentially, WOA = SOA + Web + REST. Even though it may sound complicated, understanding how WOA applies to your enterprise will be critical to achieving success in applying SOA to the Web and entering the brave new world of Web 2.0. Key Issues * What is WOA, and how does it relate to SOA and other Web-related constructs? * How will users adopt WOA, and how will vendors help them do so? * What is the future of WOA? 』

引述 :『REST * Messages are represented in plain XML * HTTP is used for the transfer protocol * HTTP verbs are used for access/manipulation commands * URIs are used to uniquely identify resources in message * HTTP authentication provides security * There is no formal method for expressing the interface contract SOAP * Messages are represented in a standardized XML SOAP "envelope" * Can be bound to various protocols including HTTP and SMTP * Access to and manipulation of data are application specific * Security is not described by SOAP and is to be provided by the developer * XML schemas are used to define the contract between client and service 』
