【 摘 要 】

Different web-enabled devices have different input, output, hardware, software, network and browser capabilities. In order for a web server or web-based application to provide optimized content to different clients it requires a description of the capabilities of the client known as the delivery context. Recently two new compatible standards have been created for describing delivery context: Composite Capabilities / Preferences Profile (CC/PP) created by the W3C and User Agent Profile (UAProf) created by the WAP Forum. DELI is an open-source library developed at HP Labs that allows Java servlets to resolve HTTP requests containing delivery context information from CC/PP or UAProf capable devices and query the resolved profile. It also provides support for legacy devices so that the proprietary delivery context descriptions currently used by applications can be replaced by standardised CC/PP descriptions. 21 Pages
