A.1 Les sch´emas UPS
Les sch´emas UPS d´ecrivent les capacit´es et les pr´ef´erences des entit´es qui peuvent intervenir dans la chaˆıne d’adaptation allant du serveur de contenu vers le terminal cible. Les profils sont analys´es syntaxiquement et tout information pertinente par rapport au processus d’adaptation est prise en compte. UPS inclut six sch´emas :
1. Le sch´ema de profil de client
2. Le sch´ema de profil des ressources du client
3. Le sch´ema de profil d’instance de document
4. Le sch´ema de profil des ressources du contenu
5. Le sch´ema de profil des m´ethodes d’adaptation
6. Le sch´ema de profil du r´eseau
