JISC's eBank UK project, which is now in phase three, has released A Study of Curation and Preservation Issues in the eCrystals Data Repository and Proposed Federation, which addresses key issues related to the establishment of the eCrystals Federation.
Here's an excerpt from "eBank Phase 3: Transitioning to the eCrystals Federation" that explains the overall project:
This project will progress the establishment of a global Federation of data repositories for crystallography by performing a scoping study into the feasibility of constructing a network of data repositories: the eCrystals Federation. The Federation approach is presented as an innovative domain model to promote Open Access to data more widely and to facilitate take-up.
It builds on the work of the eBank project, and has links to Repository for the Laboratory (R4L), SPECTRa and SMART Tea projects in chemistry. The Federation will contribute to the development of a digital repository e-infrastructure for research and will inform the Repository Support Project. . . .
In Phase 3, partners will assess organisational issues and promote advocacy, examine interoperability associated with research workflow and data deposit, harmonise the metadata application profiles from repositories operating on different platforms (EPrints, DSpace & ReciprocalNet), investigate aggregation issues arising from harvesting metadata from repositories situated within the information environments developed in other countries (EU, USA & Australia) and scope the issues of the Federation of institutional archives interoperating with an international subject archive (IUCr).
