JISC has released EMBRACE—EMBedding Repositories And Consortial Enhancement—Final Report.
Here's an excerpt:
EMBRACE (EMBedding Repositories And Consortial Enhancement) was an 18-month project led by UCL on behalf of the SHERPA-LEAP (London Eprints Access Project) Consortium, a group of 13 University of London institutions with institutional repositories.
The project had two strands, technical and strategic. In its technical strand, EMBRACE aimed to implement a number of technical improvements to enhance the functionality of the SHERPA-LEAP repositories. In a concurrent strategic strand, EMBRACE set out to investigate the challenges of embedding repositories of digital assets in institutional strategy to ensure repository sustainability.
