ORE will develop specifications that allow distributed repositories to exchange information about their constituent digital objects. These specifications will include approaches for representing digital objects and repository services that facilitate access and ingest of these representations. The specifications will enable a new generation of cross-repository services that leverage the intrinsic value of digital objects beyond the borders of hosting repositories. Software developers used OAI-ORE at the recent Open Repositories Conference to move digital objects to and from different repository software platforms as proof of concept

The CARMEN Neuroinformatics Project (Code Analysis, Repository and Modelling for e-Neuroscience) is a four-year e-Science pilot project funded by the EPSRC. The objective of the project is to create a virtual laboratory in which data on neuronal activity (electrical and optical measures) can be shared, stored, manipulated and modelled. The project currently involves a consortium of 20 academic investigators from 11 universities as well as commercial and international associates, but will expand to include new core partners over the coming years. CARMEN is supported by the Engineering and Physical Sciences Research Council (EPSRC).

"The DCMI Scholarly Communications Community is a forum for individuals and organisations to exchange information, knowledge and general discussion on issues relating to using Dublin Core for describing research papers, scholarly texts, data objects and other resources created and used within scholarly communications. This includes providing a forum for discussion around the Eprints Application Profile, also known as the Scholarly Works Application Profile (SWAP) (http://www.ukoln.ac.uk/repositories/digirep/index/Eprints_Application_Profile) and for other existing and future application profiles created to describe items of scholarly communication."
