Reactivity on theWeb is an emerging research issue covering: updating data on the Web, exchanging informa-tion about events (such as executed updates) between Web sites, and reacting to combinationsof such events. Following a declarative approach to reactivity on the Web, a novel reactive lan-guage called XChange is proposed. Novelties of the language are represented by the proposeddata metaphor intended to ease the language understanding and the supported reactive featurestailored to the characteristics of the Web. Realising this pressuposed re ning, extending, andadapting to a new medium some of the concepts on which active database systems are builtupon.
