We offer a first classification and outline of conceivable details for a design of data spaces and data ecosystems.
In this consequence, we discuss to what extent the terms data space and data ecosystem could be distinguished from each other.
There are already numerous frameworks and initiatives for decentralised, sovereign data spaces and data ecosystems, which are at different stages of implementation, some of which we elaborate on.
Currently, we observe numerous open sets of questions that pop up again and again in discussions on data spaces and data ecosystems. These include definition of terms, (de)centralisation of roles and processes, as well as questions of economic efficiency and sustainability.
