1.1 UAPROF User Agent Profile

El problema de la heterogeneidad (en términos de diferentes tipos de dispositivo de acceso, ancho de banda de la red, preferencias y características del usuario, etc.) es uno de los grandes inconvenientes que ha de ser resuelto en Internet. Para la determinación de las características tecnológicas de los dispositivos con acceso a Internet, se utilizarán dos estándares: CC/PP (Composite Capabilities / Preferences Profile) para la modelización del perfil de los usuarios y UAProf (User Agent Profile) para dispositivos WAP. Estos dos estándares, están basados en RDF (Resource Description Framework), y permiten describir y administrar las características tecnológicas del usuario. Está diseñado para trabajar con una amplia variedad de dispositivos con capacidad de acceso a Internet (tales como PDAs, PC de escritorio, portátiles, teléfonos móviles, etc.). De esta forma, cuando se realiza una petición al servidor, es posible enviar a través de CC/PP y UAProf información sobre las capacidades del dispositivo, a fin de que este último pueda entregar los contenidos adaptados teniendo en cuenta estas características. UAPROF básicamente advierte de las capacidades de los terminales a los servidores de aplicaciones y otras entidades con objeto de adaptar los contenidos a dichas capacidades. [10]

UAPROF al igual que CC/PP se divide en componentes y éstos a su vez se dividen en atributos. Los distintos componentes en los que se divide son:

· HardwarePlatform Component · SoftwarePlatform Component · NetworkCharacteristics Component · BrowserUA Component · WapCharacteristics Component · PushCharacteristics Component · CurrentBearerService Authoritative Values · SupportedBearers Authoritative Values · JavaPlatform Authoritative Values

El esquema completo de UAPROF con los componentes y atributos es: [11]
