Reactivity on the web: paradigms and applications of the language XChange
François Bry, Michael Eckert, Paula-Lavinia Pătrânjan · 2006
Reactivity on the Web is an emerging research issue covering: updating data on the Web, exchanging information about events (such as executed updates) between Web sites, and reacting to combinations of such events. Reactivity plays an important role for upcoming Web systems such as online marketplaces, adaptive, Semantic Web systems as well as Web services and Grids. After motivating the need for reactivity on the Web through an application scenario, this article introduces the paradigms upon which the high-level language XChange for programming reactive behaviour and distributed applications on the Web relies. Then, it briefly presents the main syntactical constructs of XChange. Finally, it sketches the implementation of a reactive Web-based application in XChange. 1
