The UK funding councils have issued proposals for open access to research outputs in the next Research Exellence Framework after 2014. The proposals recognise "the significant role of institutional repositories in increasing sustainable and convenient public access to research" and do not express a preference for 'gold' or 'green' routes. The proposals also cover funding body expectations, embargo periods, monograph publication and principles of open data.
