Audit and Certification of Digital Repositories: Creating a Mandate for the Digital Curation Centre (DCC)

The article examines the issues surrounding the audit and certification of digital repositories in light of the work that the RLG/NARA Task Force did to draw up guidelines and the need for these guidelines to be validated.

Repository as a service (RaaS)

In his oft-quoted seminal paper ‘Institutional Repositories: Essential Infrastructure For Scholarship In The Digital Age’ Clifford Lynch (2003) described the Institutional Repository as “a set of services that a university offers to the members of its community for the management and dissemination of digital materials created by the institution and its community members.” This paper seeks instead to define the repository service at a more primitive level, without the specialism of being an ‘Institutional Repository’, and looks at how it can viewed as providing a service within appropriate boundaries, and what that could mean for the future development of repositories, our expectations of what repositories should be, and how they could fit into the set of services required to deliver an Institutional Repository service as describe by Lynch.<br/

Optimising metadata workflows in a distributed information environment

The different purposes present within a distributed information environment create the potential for repositories to enhance their metadata by capitalising on the diversity of metadata available for any given object. This paper presents three conceptual reference models required to achieve this optimisation of metadata workflow: the ecology of repositories, the object lifecycle model, and the metadata lifecycle model. It suggests a methodology for developing the metadata lifecycle model, and illustrates how it might be used to enhance metadata within a network of repositories and services

HaIRST: Harvesting Institutional Resources in Scotland Testbed. Final Project Report

The HaIRST project conducted research into the design, implementation and deployment of a pilot service for UK-wide access of autonomously created institutional resources in Scotland, the aim being to investigate and advise on some of the technical, cultural, and organisational requirements associated with the deposit, disclosure, and discovery of institutional resources in the JISC Information Environment. The project involved a consortium of Scottish higher and further education institutions, with significant assistance from the Scottish Library and Information Council. The project investigated the use of technologies based on the Open Archives Initiative (OAI), including the implementation of OAI-compatible repositories for metadata which describe and link to institutional digital resources, the use of the OAI protocol for metadata harvesting (OAI-PMH) to automatically copy the metadata from multiple repositories to a central repository, and the creation of a service to search and identify resources described in the central repository. An important aim of the project was to identify issues of metadata interoperability arising from the requirements of individual institutional repositories and their impact on services based on the aggregation of metadata through harvesting. The project also sought to investigate issues in using these technologies for a wide range of resources including learning, teaching and administrative materials as well as the research and scholarly communication materials considered by many of the other projects in the JISC Focus on Access to Institutional Resources (FAIR) Programme, of which HaIRST was a part. The project tested and implemented a number of open source software packages supporting OAI, and was successful in creating a pilot service which provides effective information retrieval of a range of resources created by the project consortium institutions. The pilot service has been extended to cover research and scholarly communication materials produced by other Scottish universities, and administrative materials produced by a non-educational institution in Scotland. It is an effective testbed for further research and development in these areas. The project has worked extensively with a new OAI standard for 'static repositories' which offers a low-barrier, low-cost mechanism for participation in OAI-based consortia by smaller institutions with a low volume of resources. The project identified and successfully tested tools for transforming pre-existing metadata into a format compliant with OAI standards. The project identified and assessed OAI-related documentation in English from around the world, and has produced metadata for retrieving and accessing it. The project created a Web-based advisory service for institutions and consortia. The OAI Scotland Information Service (OAISIS) provides links to related standards, guidance and documentation, and discusses the findings of HaIRST relating to interoperability and the pilot harvesting service. The project found that open source packages relating to OAI can be installed and made to interoperate to create a viable method of sharing institutional resources within a consortium. HaIRST identified issues affecting the interoperability of shared metadata and suggested ways of resolving them to improve the effectiveness and efficiency of shared information retrieval environments based on OAI. The project demonstrated that application of OAI technologies to administrative materials is an effective way for institutions to meet obligations under Freedom of Information legislation

The Role of Evidence in Establishing Trust in Repositories

This article arises from work by the Digital Curation Centre (DCC) Working Group examining mechanisms to roll out audit and certification services for digital repositories in the United Kingdom. Our attempt to develop a program for applying audit and certification processes and tools took as its starting point the RLG-NARA Audit Checklist for Certifying Digital Repositories. Our intention was to appraise critically the checklist and conceive a means of applying its mechanics within a diverse range of repository environments. We were struck by the realization that while a great deal of effort has been invested in determining the characteristics of a 'trusted digital repository', far less effort has concentrated on the ways in which the presence of the attributes can be demonstrated and their qualities measured. With this in mind we sought to explore the role of evidence within the certification process, and to identify examples of the types of evidence (e.g., documentary, observational, and testimonial) that might be desirable during the course of a repository audit.

Illinois Digital Scholarship: Preserving and Accessing the Digital Past, Present, and Future

Since the University's establishment in 1867, its scholarly output has been issued primarily in print, and the University Library and Archives have been readily able to collect, preserve, and to provide access to that output. Today, technological, economic, political and social forces are buffeting all means of scholarly communication. Scholars, academic institutions and publishers are engaged in debate about the impact of digital scholarship and open access publishing on the promotion and tenure process. The upsurge in digital scholarship affects many aspects of the academic enterprise, including how we record, evaluate, preserve, organize and disseminate scholarly work. The result has left the Library with no ready means by which to archive digitally produced publications, reports, presentations, and learning objects, much of which cannot be adequately represented in print form. In this incredibly fluid environment of digital scholarship, the critical question of how we will collect, preserve, and manage access to this important part of the University scholarly record demands a rational and forward-looking plan - one that includes perspectives from diverse scholarly disciplines, incorporates significant research breakthroughs in information science and computer science, and makes effective projections for future integration within the Library and computing services as a part of the campus infrastructure.Prepared jointly by the University of Illinois Library and CITES at the University of Illinois at Urbana-Champaig

New wine in old bottles: current developments in digital delivery and dissemination

The purpose of this paper is to identify and assess current developments in scholarly publishing in Europe. Current models for disseminating content have limitations and Open Access models of publishing have been endorsed by the European Universities Association. The Harvard mandate for the deposit of materials in Open Access repositories is a bold new development, and the community is watching it with interest. It is possible that e-books may be the next large form of content to be made available to the user. Users certainly express interest in using this form of material. However, current library systems need to be developed in order to cope with this mass of new content. E-theses, available in Open Access from institutional repositories, are a form of content that is made much more visible than the paper equivalents. The DART-Europe portal, supported by LIBER (Association of European Research Libraries) currently provides access to 100,000 research theses in 150 European Universities. At an institutional and academic level, however, much remains to be done to embed Open Access into the landscape: the current situation is described in a new report for UCL (University College London), produced by RAND Europe

Repository Interface for Overlaid Journal Archives: costs estimates and sustainability issues

The RIOJA project (http://www.ucl.ac.uk/ls/rioja) investigated the feasibility of an overlay journal model in collaboration with the arXiv and in the scientific domain of astrophysics and cosmology. Scientists in this community are active users of e-prints repositories such as the arXiv. Furthermore, they have the support of Professional Associations and Learned Societies that have been pioneers in adapting to new publishing models and in particular electronic journals. Long term access to information as well as maintaining provision to sustainable systems/services is important to various parties in the scholarly communication system: the creators of information, developers and managers of services, libraries, publishers, funders and also users. Although scientific journals have been in existence since the 18th century (Lawal, 2001), factors such as increased journal subscription prices in the last decades and the emergence of new technologies have triggered discussions on the potential of new business models for publishing research. Furthermore, the advent of the open access movement also contributed to exploration of the issues around free access to information and provision of sustainable services. Exploring aspects of sustainability is something that should be seen over a period of time and whether launching, converting or simply maintaining a new or existing system/service the needs of the community it serves should be taken into account. Scientific journal publishing is a complex process. Besides disseminating scientific knowledge, registration of a claim for new discovery and a quality “stamp” it also facilitates social factors. Besides making research findings available and contributing to the advancement of knowledge, publishing is also a means for measuring quality of the work of scientists, allocating funding, and acknowledging contributions to knowledge. In this report, we will try to provide an overview of a new publishing model, that of the overlay journal. We will discuss the use of the arXiv by scientists in astrophysics and cosmology as well as the role of professional associations and learned societies in the publishing process for this community. We will briefly explain the methods employed to compile this report. We will also briefly present the RIOJA toolkit before we try and identify costs in the publishing process associated with the functions of registration, certification, and awareness and archiving. This report does not aim to provide a comprehensive report of actual journal publishing costings. Despite the fact that there are studies in existence that tried to document costs associated with journal publishing, the information presented there rarely corresponds to the actual costs of individual journal functions. In addition, the interviews with publishers and editors did not reveal any substantial information about costings that have not already been reported in the literature or are available on some publishers' websites. Where appropriate, this report aims to acknowledge studies conducted previously as pointers to further reading and, where applicable, to compare reported findings to observations made during the development and implementation of the RIOJA toolkit (described below). We will conclude this report with some of the issues reported in the literature around sustainability of services and some brief suggestions for further work

Pathways: Augmenting interoperability across scholarly repositories

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).Comment: 18 pages.

Building scalable digital library ingestion pipelines using microservices

CORE, a harvesting service offering access to millions of open access research papers from around the world, has shifted its harvesting process from following a monolithic approach to the adoption of a microservices infrastructure. In this paper, we explain how we rearranged and re-scheduled our old ingestion pipeline, present CORE's move to managing microservices and outline the tools we use in a new and optimised ingestion system. In addition, we discuss the ineffciencies of our old harvesting process, the advantages, and challenges of our new ingestion system and our future plans. We conclude that via the adoption of microservices architecture we managed to achieve a scalable and distributed system that would assist with CORE's future performance and evolution
