Composite Capability/Preference Profiles (CC/PP): A user side framework for content negotiation

In this note we describe a method for using RDF, the Resource Description Format of the W3C, to create a general, yet extensible framework for describing user preferences and device capabilities. This information can be provided by the user to servers and content providers. The servers can use this information describing the user's preferences to customize the service or content provided. The ability of RDF to reference profile information via URLs assists in minimizing the number of network transactions required to adapt content to a device, while the framework fits well into the current and future protocols being developed a the W3C and the WAP Forum.
