This paper examines the theoretical and practical development of informational commons in the digitised and interconnected environment. This is done by looking at the theory behind intellectual property and licenses in their role of creating and maintaining the commons. This paper will also present the practical work in the form of describing a large-scale development project concerning the localisation of the creative commons licenses to the Swedish jurisdiction. The goal of this work is to provide practical and theoretical foundations in the study of the role of informational commons in the knowledge society.
