Reactive programming and event-based programming are two closely related programming styles that are becoming ever more important with the advent of advanced HPC technology and the ever-increasing requirement for our applications to run on the web or on collaborating mobile devices. A number of publications on middleware and language design — so-called reactive and event-based languages and systems (REBLS) — have already seen the light, but the field still raises several questions. For example, the interaction with mainstream language concepts is poorly understood, implementation technology is in its infancy and modularity mechanisms are almost totally lacking. Moreover, large applications are still to be developed and patterns and tools for developing reactive applications are an area that is vastly unexplored.
This workshop will gather researchers in reactive and event-based languages and systems. The goal of the workshop is to exchange new technical research results and to define better the field by coming up with taxonomies and overviews of the existing work.
