Open Stewardship is currently in formation. The mission is to invite, promote and extend the practice of Open Stewardship. Stewardship, as an ethic, implies taking responsibility for and managing a collective resource. Open Stewardship is a way of thinking, acting, and being that invites and facilitates the ongoing care and co-creation of shared resources within complex, fluid environments. These shared resources can be understood in the narrow sense of code, concepts, or designs. Shared resources can be understood in a broader sense to include our environments — both our online environments, and the places we live (our cities, towns, neighborhoods). Finally, our shared resources include our collective social contexts – our groups, organizations, institutions, and networks. Open Stewardship invites and facilitates the care and development of these resources in the context of ever-expanding networks of projects and concerns.
