“…The desire to federate repositories in such a manner actually also emerges as a result of the understanding that no single digital library hosts all artifacts that are relevant for a specific subject domain, community, or application. The proposition of a "single repository behavior" exposed by a federation consisting of any number of distributed repositories is appealing, and has been the subject of digital library interoperability efforts such as Dienst [22], NCSTRL [8], CORDRA [36,33,15], DRIVER [9], and the Chinese DSpace federation [38]. Both federation paths, on one hand the federation of multiple instances of a specific repository installation, and on the other hand the federation of distributed repositories, reveal another dimension of the The aDORe Federation Architecture 3 scalability problem in contemporary digital library efforts.…”

The aDORe federation architecture: digital repositories at scale

The need to federate repositories emerges in two distinctive scenarios. In one scenario, scalability-related problems in the operation of a repository reach a point beyond which continued service requires parallelization and hence federation of the repository infrastructure. In the other scenario, multiple distributed repositories manage collections of interest to certain communities or applications, and federation is an approach to present a unified perspective across these repositories. The high-level, 3-Tier aDORe federation architecture can be used as a guideline to federate repositories in both cases. This paper describes the architecture, consisting of core interfaces for federated repositories in Tier-1, two shared infrastructure components in Tier-2, and a single-point of access to the federation in Tier-3. The paper also illustrates two large-scale deployments of the aDORe federation architecture: the aDORe Archive repository (over 100,000,000 digital objects) at the Los Alamos National Laboratory and the Ghent University Image Repository federation (multiple terabytes of image files).

Pathways: augmenting interoperability across scholarly repositories

et al. 2007

In the emerging eScience environment, repositories of papers, datasets, software, etc., should be the foundation of a global and natively-digital scholarly communications system. The current infrastructure falls far short of this goal. Cross-repository interoperability must be augmented to support the many workflows and value-chains involved in scholarly communication. This will not be achieved through the promotion of single repository architecture or content representation, but instead requires an interoperability framework to connect the many heterogeneous systems that will exist.We present a simple data model and service architecture that augments repository interoperability to enable scholarly value-chains to be implemented. We describe an experiment that demonstrates how the proposed infrastructure can be deployed to implement the workflow involved in the creation of an overlay journal over several different repository systems (Fedora, aDORe, DSpace and arXiv).
