“…Borrowed from geography, the ecosystem metaphor is used to describe a "system of people, practices, values, and technologies in a particular local environment" (Harrison, Prado and Cook, 2012, p. 906) by highlighting the various interactions and interdependencies of its components. Open data ecosystems have been analyzed from different aspects: their temporal evolutions (Heimstädt et al, 2014), their compositions (Immonen, Palviainen and Ovaska, 2014;Zuiderwijk, Janssen and Davis, 2014;Ponte, 2015;Lindman and Kuk, 2015), the role of intermediaries (Van Schalkwyk, Willmers and McNaughton, 2016), business models (Kitsios, Papachristos and Kamariotou, 2017) or legal constraints (Kassen, 2018). Among this literature, a number of researchers have described the roles and functions of actors in various ecosystems.…”
