Each preference is encoded in an everyday artefact, and the registration of the preference to a user's personal coordination server occurs automatically by closing or attaching the everyday artefact to his/her personal coordination server. Our personalization framework offers several ways to personalize the services of a personal coordination server by using the everyday artefact.
