CINET: Network Science MiddlewareNSF SDCI 1032677The research will develop a cyber infrastructure middleware (CINET) to support Network Science.CINET will be pervasive, flexible and extensible. Users can contribute new networks, data, methods, hardware, and research results in an integrative way.CINET will enable new ways by which researchers study and teach complex networks.
