Digital Curation and Trusted Repositories: Steps Toward Success
Christopher A Lee, Helen R. Tibbo

Nationwide Census of Institutional Repositories: Preliminary Findings
Karen Markey, Beth St. Jean, Soo Young Rieh, Elizabeth Yakel, Jihyun Kim, Yong-Mi Kim

The MIRACLE (Making Institutional Repositories A Collaborative Learning Environment) Project is a multi-phased research project that is investigating the development of institutional repositories (IRs) in U. S. colleges and universities to identify models and best practices in the administration, technical infrastructure, access to, and preservation of repository collections. This paper features preliminary findings from the project’s first phase, a nationwide census that will reveal the extent of college and university involvement with IRs in the United States. Preliminary findings address the types of investigative activities that institutions are conducting prior to making the decision to implement an IR, perceived benefits of IRs, staffing for IRs, methods of recruiting digital content, characteristics of operational IRs including their costs, and participating institutions’ next steps on the road to implementing an IR.


If you build it, will it fly? Criteria for success in a digital repository
Kenneth Thibodeau

International collaborations have produced a standard describing the functions of a digital repository and the characteristics of one that can be trusted. These results provide an abstract frame of reference for evaluating such repositories, but meaningful evaluation requires that they be supplemented by empirical data on the purpose of each repository and the institutional, cultural and resource context in which it operates. Informed evaluation will consider how a repository balances the competing objectives of preservation and dissemination, whether it is defined primarily in terms of a community of producers or a community or users, and the extent to which it operates in isolation or in collaboration with other institutions.


Motivating and Impeding Factors Affecting Faculty Contribution to Institutional Repositories
Jihyun Kim

Institutional Repositories (IRs) are predicated on contributions by members of a university community, particularly faculty members. In fact, faculty contribution is considered one of the success factors for an IR even though several studies have found low rates of faculty submission. In order to learn how we might be able to address this problem, the present study investigated factors that motivate or impede faculty contribution. A conceptual model of the factors was proposed based on the Socio-Technical Network Model and Social Exchange Theory. A survey was conducted based on a sample of 67 professors whose materials were deposited in the DSpace IR of a major research university. 31 out of 67 (46.3%) responded the survey. Findings indicate that faculty members who had planned to contribute to the IR in the future agreed more strongly with accessibility and publicity of open access materials and possess a greater altruistic intention to make their work publicly accessible. The faculty members who perceived an influence of a grant-awarding body on their decision to self-archive were much less likely than others to contribute to the IR. Since the survey was performed as a pilot study, a larger survey and follow-up interviews will be conducted to investigate these factors in greater detail.


Metadata Use in OAI-Compliant Institutional Repositories
Miles Efron

This preliminary study examines the use of Dublin Core (DC) metadata in Institutional Repositories (IRs) that participate in the Open Archives Initiative (OAI). The study concerns evaluating IRs with respect to the quality of their indexing. In particular, I argue that in order to support successful retrieval of information, IR developers should endeavor to populate their indexes with well-structured metadata. The current study provides an initial motivation for this argument by analyzing the degree to which presently available IR metadata evidences such structure.


Services Make the Repository
Anne Sauer

This paper provides an overview of the collaboration between the Perseus Project and the Digital Collection and Archives (DCA) at Tufts University in moving the collections of the Perseus Project into the DCA's Fedora based repository as well as a listing of potential services necessary to support a successful institutional repository.


Building Relationships Project Update 2007
Jonathan David Crabtree

In the digital age, what is the best way to build and sustain data archives? Collaborating with other archives could improve how they operate and grow, but building relationships consumes time and scarce resources. Is it worth the effort? Six major digital archives are exploring this issue through a partnership funded by the Library of Congress Infrastructure and Preservation Program. This partnership a federated approach to data archives require building relationships at the producer, administrative, and program application development levels. Now two years into its development, this alliance has accomplished a number of important objectives in each of these realms. This paper highlights the experiences of two alliance members, the ICPSR and the Odum Institute. Our interactions and accomplishments lead us to believe that the benefits of partnerships such as this one far exceed the costs they entail. More particularly, establishing collaborative relationships between archives achieves four objectives, as follows: (1) It facilitates communications between archiving professionals, enhancing efficiency by creating a common pool of knowledge and a framework for ongoing interactions and education; (2) It improves our relationships with data providers by enabling us to provide a better and more durable quality of service; (3) It allows archivists to build networks of relationships with software developers, increasing the probability of identifying, developing, and adopting broadly functional applications serving a multiplicity of needs and audiences; and (4) In promoting development and adoption of common standards, it dramatically improves the probability of effectively networked collections and diminishing the costs involved in creating them. While our focus is social science data, the approach would work in many fields.


Government Archives and the Digital Repository Audit Checklist
Bruce I Ambacher

This article examines the RLG/NARA draft Audit Checklist for the Certification of Trusted Digital Repositories from the perspective of publicly funded repositories, especially government archives. It reviews the historical origins of the checklist, the comments received from government archives on the metrics in the draft document and the task force’s adjudication of those comments. Finally it addresses some unresolved issues.


The nestor Catalogue of Criteria for Trusted Digital Repository Evaluation and Certification
Susanne Dobratz, Astrid Schoger, Stefan Strathmann

This paper describes the general approach nestor – the German “Network of Expertise in Long-Term Storage of Digital Resources” has taken in order to design a catalogue of criteria for trusted digital repositories used for long-term preservation issues. Further developments are intended to led to the implementation of evaluation schemas and a formal certification process for trusted digital repositories.


Automated Validation of Trusted Digital Repository Assessment Criteria
Reagan W. Moore, MacKenzie Smith

The RLG/NARA trusted digital repository (TDR) certification checklist defines a set of preservation assessment criteria. The criteria can be mapped into management policies that define how a digital preservation environment is operated. We explore how these management policies can be automated through their characterization as rules that control preservation services. By integrating a rule-based data management system with the DSpace digital library, we expect to demonstrate automated audits of the TDR checklist. The system is sufficiently general that one can also demonstrate the completeness and self-consistency of preservation environments. This is the concept that all required preservation metadata are controlled by management policies, and that for each management policy the required preservation metadata are preserved.
