This special issue of the Electronic Journal of Digital Enterprise (e-JDE), on Concepts and Tools for Knowledge Management (KM), develops the argument that the governance of knowledge seems to be the Scientific Policy able to creating value with regard of human and its evolution in cultures and civilizations. The duty of good governance is a consideration of the transfer of knowledge related to scientific and technological progress. Intrinsically, this process requires a system of organization and knowledge management by implementing knowledge production and its influence in society. The objective of the ISKO-Maghreb Chapter is to contribute in understanding the factors that organize knowledge and phenomena that affect the information society. Actions to be undertaken by the scientific ISKO society must take into account socio-cultural, cognitive and economic in the strategic management of knowledge. Towards the knowledge society, it should be seen in its dynamic, its content and its interaction with science and technology associated to universities, companies and politics. In this context, a first orientation is pedagogical attempt to answer the question "what is known about the knowledge and its organization?". Then the issue is moving towards the societal issues of knowledge, theory and practice, to provide clarification to a convergence of KM (Knowledge Management) approaches. Education, science, culture, communication and technology remain the major themes covered by ISKO-Maghreb, for the development of the knowledge organization, expertise management and collective intelligence.
