There has been a long outstanding need for support of hierarchical storage in the Fedora Repository and related components. Recent events have underscored that this need has again moved to the forefront with increasing use of the Fedora Repository in research applications. Examples include UPEI's Virtual Research Environment (VRE) deployments using Islandora, Max Planck Institutes eSciDoc (Fiz Karlsruhe) and the emerging NSF Cyberinfrastructure program. Other products such as the DICE iRODS and SDSC SRB have provided a means to virtualize storage including support for hierarchical storage. Increased interest in using Fedora to store high performance computing (HPC) data has been reported from a number of institution. There have also been requests from institutional repository and humanities researchers who have large collections for the addition of this feature.
In this space, we will be exploring the requirements related to supporting hierarchical storage and enabling the community in adding support to Fedora Commons components. The goal of this work is to produce a Hierarchical Storage Module (HSM) integration for Fedora Commons.
