Evolution of Distributed Web Data: An Application of the Reactive Language XChange
François Bry, Michael Eckert, Hendrik Grallert, Paula-Lavinia Pătrânjan · 2007
Many data sources on the Web evolve: they change their content over time, typically as reactions to events. Such changes often need to be mirrored in data on other Web nodes: updates need to be propagated. To respond to the need for evolution and reactivity both locally and globally, the language XChange has been developed. We demonstrate its applicability in a concrete scenario of distributed Web sites of a scientific community with mutual data dependencies.
