There is no shortage of reports highlighting Germany’s and Europe’s serious technological dependencies: social networks, cloud services, artificial intelligence – they are lagging in many areas and in danger of being left behind altogether. The lack of digital sovereignty did not arise suddenly, but in times of intensifying geopolitical conflicts, it now appears threatening. Europe is missing economic opportunities and has no influence on the design of the technologies. The technological dependencies also affect data sharing: citizens and companies in Europe are exposed to the risk of critical data being leaked. But what exactly are these dependencies and how do they affect everyday data sharing? What are the prospects for developing greater digital sovereignty?

all ShareCast episodesEpisode 8: Digital Sovereignty: Deciding how to shareDigital sovereignty is one of the key concepts in the debate on digital policy – and is often used to highlight the lack of sovereignty in the digital sphere. This lack did not arise suddenly, but in times of intensifying geopolitical conflicts, these dependencies now appear threatening. What are these dependencies and how do they affect data sharing? And what are the prospects for developing greater digital sovereignty? That’s what episode 8 of ShareCast is all about. | listen now
Episode 7: A dream of open knowledge: data sharing in scienceThe seventh episode deals with an entire area of modern society: science. We explore the significance of sharing digital data for scientific work and discuss the opportunities and challenges currently being debated in this field. | listen now
Episode 6: Open source software: shared or closed?Open source software is software under free licences that grants its users four freedoms: to run the software for any purpose, to examine how it works and thus also its source code, to adapt it to their own needs, and to redistribute the software, even in modified versions. This distinguishes it from software that the open source movement refers to as ‘proprietary’ or ‘closed source software,’ which does not offer these ‘fundamental freedoms.’ But how exactly is collaboration and sharing carried out here? What interests determine the open source world, and what conflicts exist? | listen now
Episode 5: Data, Forests, and TimberThe fifth episode of ShareCast focuses on the data generated in the forest and forestry and timber industries. How is this data created? What is it used for? Who has an interest in it? Why is this data not shared? What stands in the way of this? What potential could be realized if this were to succeed? And how could the obstacles to data sharing in forestry and the timber industry be removed? | listen now
Episode 4: Connected Cars: Improvement or Data Hogs?Having your own car was once a great promise of freedom. Getting into the car and being able to drive wherever we wanted. And keep to yourself: With your partner or family. This image of the car is still there – and yet another one is slowly taking over. Cars are now highly networked, high-performance machines that are constantly filming, recording and measuring. The manufacturer is virtually at the wheel. | listen now
Episode 3: Smart City: Data Overload?In the third episode of ShareCast, we talk about the interplay between data and urban development. We take a look at what is associated with the term smart city and discuss the potential and challenges that smart city concepts entail. | listen now
Episode 2: Health Data: Just for Me or Donation?On the one hand, the sharing of data is intended to provide a major boost to innovation in medical research and help improve healthcare. On the other hand, health data is extremely sensitive data, i.e. data with a clear personal reference that can cause great harm in the wrong hands. This difficult balancing act is illustrated very clearly when it comes to so-called rare diseases. | listen now
Episode 1: Data: Nothing (easier) to share?We shed light on some of the things behind buzzwords such as sharing economy, data silo, platform economy and open science. And we examine the heterogeneous understandings that are associated with sharing: voluntarily giving away data for a specific purpose, sharing data with a counterpart, passing on data in a group or making data openly available to everyone – these are very different things. | listen now
