Concept and project
a shared pool of information which, unlike a physical commons, is not subject to the physical constraints of scarcity 
A project initiated by Lawrence Lessig and incubated by Creative Commons with the purpose of enabling a platform for commons-related projects from around the world to interact — including A2K, Wikipedia, Free Software, Free Culture Movement and Creative Commons..
From their website:
iCommons is an organisation with a broad vision to develop a united global commons front by collaborating with open education, access to knowledge, free software, open access publishing and free culture communities around the world.
Using the annual iCommons Summit as the main driver of this vision, iCommons will feature projects that encourage collaboration across borders and communities, and promote the tools, models and practice that facilitate universal participation in the cultural and knowledge domains. The Summit will collaborate with organisations and communities from around the world to demonstrate and share best practice and discuss strategies for continuing the positive impact that “sharing” practices are having on participation in the cultural and knowledge domains.
During the year iCommons will incubate projects that cross borders and unite commons communities, acting as a platform for international collaboration towards the growth and enlivening of a global digital commons.
