Project

The Akubra Storage Delegation Project is a new effort developed jointly by the Fedora and Topaz project teams as the first area of joint architecture work. The goal of Akubra is to provide a pluggable storage component that supports transactions on common file systems plus the ability to support multiple customized storage options at the same time. Akubra was a result of the architecture analysis by the Fedora and Topaz developers that concluded that the best opportunity for moving forward on joint architecture was to focus on building open source components to facilitate better integration of the low-level storage of files/bitstreams/blobs, and pluggability of heterogeneous underlying storage systems. We plan to integrate the new Akubra software with both the Topaz OTM and the Fedora Repository service. The primary intent is to create better abstraction and separation of concerns between file/bitstream/blob storage, and the services that Topaz and Fedora provides over them. Once this is done, there will be more flexibility in terms of how Topaz and Fedora can evolve architecturally.an overarching project for storage-related needs of open source content systems. It includes the Akubra Project as a subproject but is intended to support the wider scope of use cases found in the open source content community. A major part of this project is a collaboration between DSpace and Fedora Commons.
