At first it was used by a small a small passionate community, but now the full force of the open philosophy is impacting the “traditional” economy. In every area, from industry, education, culture, and science to of course information and data, we are seeing opening of data, knowledge, and trade secrets. Why? Because a new wave of collaboration is crashing over the world, but also in particular because the old closed, vertical models have shown that they are powerless in an economy shaken up by the Internet and technology. This book presents a first overview of this major societal change. It decrypts the most evident effects of this substantial paradigm shift. With the help of dozens of experts and practitioners, this book seeks to make the new open business models visible in a practical way. In it informed readers and novices alike will find answers to their questions, albeit only “some” answers, not “all” the answers as we have not yet calculated the final impact of this open wave.
