An international workshop in Amsterdam in March, funded by JISC, SURF and DRIVER, discussed work needed to improve interoperability between repositories. Four areas of work were focused upon:
– citation services
– interoperable identification systems
– repository handshaking (interoperable deposit systems), and
– repository organisation (supporting repositories around the world)
There’s more information and an update here:
There is also an option to sign up to this wiki / community.
Specifically now, there is a proposal for internationally coordinated work to enable repositories of OA research papers to share the citations therein. This is currently out for public review, and your comments would be most welcome. Please see the proposal here:
There are some 15-20 funders of repositories infrastructure around the world (like JISC in the UK) also looking at this proposal, with a view to funding the work it describes.
