The United States Office of Science and Technology Policy (OSTP) delivered an open access directive in early 2013 mandating that federally funded research articles and associated data must be made accessible online to the public, free of charge. In response to this mandate, university and library organizations proposed the Shared Access Research Ecosystem (SHARE). With experience in the design and creation of large-scale federated repositories, bepress, best known for our hosted institutional repository platform Digital Commons, can offer unique insight into what makes a federated repository successful. This paper will outline the attributes of a successful shared national cross digital repository.
