Abstract: Different web-enabled devices have different input, output, hardware, software, and network capabilities. In order for a web server 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. This paper describes a number of issues, possible improvements and future directions for CC/PP and UAProf that have been identified in the course of work at HP Labs Bristol on device independence, and the creation DELI, an experimental open-source library that simplifies deploying these standards within servlets.
