ral personalization services such as context dis- covery, contextualization, matching, binding, and SO on. We argued that PAM can be deployed over different architectures to make applications adaptable and sensi- tive to user profiles and contexts. The global personalization approach we proposed was instantiated in a CDP environment to build an actual CARS. To this end, profile and context meta mod- els are given a specific semantics and structure. At the same time, PAM services are defined in a sharp way, and detailed through process and algorithms.
