Abstract:

This paper offers a perspective on the directions in which hypermedia infrastructure research will move in the next several years. The perspective is based on the authors' experiences and insights from a decade of active participation in this research area. After a review of hypermedia infrastructure research, the paper focuses on two particular threads of such research named 'multiple open services' and 'structural computing'. We believe that these threads show much promise for the future.
