UK RepositoryNet+ (RepNet) is a socio-technical infrastructure supporting deposit, curation & exposure of Open Access research literature. JISC has invested much in the growth of institutional capacity to support policies of institutional responsibility, re-usability and ease of access for content, and in a variety of components. RepNet aims to provide a stable socio-technical infrastructure at the network-level to maximize value to UK HE of that investment. Our general approach is to envision a mix of distributed and centrally delivered service components within pro-active management, operation, support and outcome. While this infrastructure will be designed to meet the needs of UK research, it is set and must operate effectively within a global context.
