Just attended the Repositories and Preservation Programme meeting in Aston Birmingham I would really recommend the talk The Institutional Perspective - How can institutions most effectively exploit work in the Repositories and Preservation field? given by Jeff Haywood- University of Edinburgh.
I would like to think this may kickstart a process to find methods by which current projects could more easily use and build on the outputs of previous projects and create a framework to more easily exchange code and ideas.
Jeff's talk was given even more currency as in the afternoon session Rachel Heery give a presentation (its on slideshare) in Repositories Roadmap Session launching her just published Digital Repositories Roadmap Review: towards a vision for research and learning in 2013
The question however remains: by then will Standing on the shoulders of Giants still be a distant concept?
