One of the most important steps toward open government is the creation of an open data ecosystem (for the purpose of this chapter, open government ecosystem can be defined as “with its emphasis on an evolving, self-organizing system of feedback and adjustment among actors and processes, to be a useful heuristic for approaching the design of effective OGD programs (p. 16)” S. Dawes, L. Vidiasova, O. Parkhimovich. Planning and designing open government data programs: An ecosystem approach, Government Information Quarterly (2016), Volume 33, Issue 1, 15–27) and an open government culture that emphasizes the need for and benefits of transparency, collaboration, and interaction. The purpose of this chapter is to introduce six interrelated and iterative principles to foster open data projects and establish fundamental components to creating an open government ecosystem.
