The rapid growth of information technology during the last decade has put governments and businesses alike in front of a number of barriers to overcome in order to tap the full potential of this new digital era. One of the most challenging, but also most potential developments, comes with the web of data (Auer et al., 2007) and the inherent mass of freely-available information, i.e., open data (Zeleti, Ojo, & Curry, 2016). Especially open government data (OGD) holds the power to unlock innovation in both sectors, government and business, regarding the development of new, better, and more cost-effective services for citizens (Zuiderwijk & Janssen, 2014a). This interaction of actors forms a highly-dynamic ecosystem of data (Hammell et al., 2012), yet has to be re-evaluated with the increasing voluntary contribution of data by citizens, e.g., through citizen science initiatives (Lampoltshammer & Scholz, 2016) and open science data initiatives in general (Karmanovskiy, Mouromtsev, Navrotskiy, Pavlov, & Radchenko, 2016). Thus, approaching this ecosystem of open data from a quadruple helix (Carayannis & Rakhmatullin, 2014) approach is the next logical step. Figure 5.1 shows such an extended version of the ecosystem.
