現今Web 2.0網站所提供的網際服務(Web service)大多是屬於REST型態的服務。REST(REpresentational State Transfer)服務是一種輕型態的網際服務，其是利用HTTP方法來存取特定的資源。對於服務導向架構的應用服務來說，由於其應用服務的核心是商業流程執行語言(BPEL)，但由於BPEL目前沒有辦法能夠支援REST型態的網際服務，所以服務導向架構的應用服務並無法利用REST型態的網際服務資源。 故本研究提出一個經由BPEL整合REST型態的服務的架構，用以整合REST以及服務導向架構之資源。將REST服務透過轉換，成為SOAP服務，讓BPEL能夠使用轉換後的SOAP服務來呼叫使用該REST服務，並能夠讓服務開發者佈署其混搭服務給予客戶使用。 At presence, Web 2.0 concept has widely accepted and realized by most of new websites. Web 2.0 brings more user-involved interactions, and harnesses the power of collective intelligence. Many software companies provide their Web 2.0 websites, like YouTube, Flickr, Delicious…etc. We found that the most services provided by a Web 2.0 website are not SOAP services but REST-style web services, called RESTful services. More and more service providers publish their services in REST fashion. Meanwhile, Service-Oriented Architecture already becomes a standard of building web application, and SOAP service is the solution of web services. The core of SOA-based application is service composition, and BPEL is the standard of service composition. However BPEL could not integrate RESTful services directly for now. Hence, we propose a framework to integrate SOAP services and RESTful services through BPEL engine enhancements. Service developers could utilize the framework to publish their composite services.
