Sage River Disaster Information (SageRDI)

The Scalable Amplified Group Environment (SAGE2) is an open-source, web-based middleware for driving tiled display walls. SAGE2 allows running multiple applications at once within its workspace. In large display walls, users tend to collaborate using multiple applications in the same space for simultaneous interaction and review. Unfortunately, many of these applications were created independently by different developers and were never intended to interoperate which greatly limits their potential reusability. SAGE2 developers face system limitations where applications are data segregated and cannot easily communicate with others. To counter this problem, we developed the SAGE2 data sharing components. We describe the Sage River Disaster Information (SageRDI) application and the SAGE2 architectural implementations necessary for its operation. SageRDI enables river.go.jp, an existing website that provides water sensor data for Japan, to interact with other SAGE2 applications without modifying the website's server, hosted files, nor any of the default SAGE2 applications.
