This document provides an overview of a presentation given by Dr. Hendrik Drachsler on learning networks and digital ecosystems. The presentation begins with an introduction to learning networks, which are online social networks designed to support lifelong learning through sharing, publishing, and adjusting knowledge resources. Examples of learning networks for medical professionals and libraries are provided. Technologies to support learning networks like personal environments, recommendation systems, and emerging paths are then discussed. The presentation then introduces digital ecosystems and compares them to learning networks. Digital ecosystems are defined as distributed adaptive open socio-technical systems inspired by natural ecosystems. Examples of digital ecosystems like those around Apple, Facebook, and Google are presented. Finally, the presentation concludes that a learning network can become a digital ecosystem when
