This book explores how the technical upheavals of the 21st century have changed the structures and architecture of the creation, sharing and regulation of knowledge. From the new economic and technical models of production and dissemination of knowledge, the book deals with all new forms of valorisation. It also explains how the legislative deficit in the world and in Europe, around digital is being filled by new initiatives, such as the law for a Digital Republic, in France. It is therefore a book that provides a valuable follow-up to the book «The New Challenges of Knowledge», of which it constitutes the continuation and operational deepening.
