“…OGD researchers and OGD practitioners have used several approaches to understand and depict OGD as a larger socio-technical system. For example, ecosystems (e.g., Immonen, Palviainen, and Ovaska, 2014;Dawes, Vidiasova, and Parkhimovich, 2016), lifecycles (e.g., Zuiderwijk, Janssen, Choenni, Meijer, and Alibaks, 2012;Attard, Orlandi, Scerri, and Auer, 2015), value networks (e.g., Attard, Orlandi, and Auer, 2016;Lindman, Kinnari, and Rossi, 2016), marketplaces (e.g., Zuiderwijk, Loukis, Alexopoulos, Janssen, and Jeffery, 2014), and value chains (e.g., Berends, Carrara, Engbers, and Vollers, 2017). In this section, I use "OGD ecosystem" as an umbrella term for the various approaches.…”
