Digital Ecosystems have been there for a while now. Most publications and books on digital ecosystems deal with theory while ignoring practice. This book discusses digital ecosystems from a design and implementation perspective. With this book, you will learn the inner-cuisine of digital ecosystems, including the architecture of their components, their languages, their protocols, their management, their communication, and of course their implementation. It is about the know-how of digital ecosystems - how to put them into real action.
