Authentication and Authorization: Security Issues for Institutional Digital Repositories :
In this digital age and the development of Information and Communication Technology (ICT) many organizations have realized the benefits of sharing information within the organization as well within the community and globally. These organizations may be corporate company, research organization or academic institutions. In the academic institutions with the higher education, information capturing, dissemination and sharing is practiced most. In spite of Open Source Drive , in the highly competitive environment, many university or colleges raise a paradox between allowing information and knowledge to flow freely, and the need to keep certain information very secure. In restricted or closed-information environment secured information channel, authorization and authentication of both users and digital contents are a burning issue today. Digital contents are managed and stored in repository to share. Repository of an institution can support research, learning, and administrative processes as well as purposes. Standards are followed for the repositories which ensure that the contents contain is accessible in that and it can be searched and retrieved for later use. A wide variety of contents may be included in the digital repositories for the multiplicity of purposes and users. It is the technical ability and administrative policy decision that what kind of materials goes into a repository (Jones, et al 2006). A proper digital repository not only requires an organized collection of digitized content, it also requires that the content be accessed and distributed as widely as possible to legitimate users around the globe. Access management and control is one of the major concerns for content-providers on the Internet. Without a proper access management mechanism confidentiality and integrity of information cannot be guaranteed. Different conventional methods are practiced by the content-providers but not a single method is sufficient for access management (Ray and Chakraborty, 2006). However, the administrators of the digital content-providers mostly expect their preferences for the technology or the procedure to be available which may be best practiced globally.

CRIS and Institutional Repositories :
CRIS (Current Research Information Systems) provide researchers, research managers, innovators, and others with a view over the research activity of a domain. IRs (institutional repositories) provide a mechanism for an organisation to showcase through OA (open access) its intellectual property. Increasingly, organizations are mandating that their employed researchers deposit peer-reviewed published material in the IR. Research funders are increasingly mandating that publications be deposited in an open access repository: some mandate a central (or subject-based) repository, some an IR. In parallel, publishers are offering OA but replacing subscription-based access with author (or author institution) payment for publishing. However, many OA repositories have metadata based on DC (Dublin Core) which is inadequate; a CERIF (Common-European Research Information Format) CRIS provides metadata describing publications with formal syntax and declared semantics thus facilitating interoperation or homogeneous access over heterogeneous sources. The formality is essential for research output metrics, which are increasingly being used to determine future funding for research organizations.

Using a CRIS for E-Infrastructure: E-Infrastructure for Scholarly Publications :
Scholarly publications are a major part of the research infrastructure. One way to make output available is to store the publications in Open Access Repositories (OAR). A Current Research Information System (CRIS) that conforms to the standard CERIF (Common European Research Information Format) could be a key component in the e-infrastructure. A CRIS provides the structure and makes it possible to interoperate the CRIS metadata at every stage of the research cycle. The international DRIVER projects are creating a European repository infrastructure. Knowledge Exchange has launched a project to develop a metadata exchange format for publications between CRIS and OAR systems.

Sciences et société en interaction sur Internet. Éléments pour une histoire de l’édition électronique en sciences humaines et sociales

Dans l’histoire des rapports complexes qu’entretiennent sciences et société, le développement des réseaux numériques constitue un moment stratégique, que ce soit au niveau de leur développement technique, ou des modifications que ce développement produit sur les formes de la communication scientifique.

Le cas particulier des sciences humaines et sociales met bien en évidence le rôle de médiation que les TIC jouent dans les relations entre sciences et société.



OA-Fachrepositorien ist ein von der DFG gefördertes Projekt der Bibliothek der Universität Konstanz. Ziel ist eine Förderung der Sichtbarkeit und Nutzung der in institutionellen Repositorien zahlreich vorhandenen Dokumente durch eine an den Bedürfnissen der Wissenschaftler orientierte geeignete Einbindung in fachliche Repositorien und andere Zielsysteme, v.a. Fachdatenbanken, die von Fachwissenschaftlern als primäre Sucheinstiege verwendet werden.

Evaluation Insights to Key Processes of Digital Repositories :
Digital repositories are considered essential information tools for scholarly communication. Their acceptability and extensive use by communities and institutions, as well as the users’ commitment in self-archiving, highlight the need for developing alternative channels of communication to expose scholarly productivity. Furthermore, the digital repositories community is interested into transforming them into viable, reliable and useful systems. This interest is primarily expressed by intense research activity, including – among the others – the evaluation and the usability of the technological solutions that support these services. On an institutional level, digital repositories are systems supported by physical organizations, such as libraries, which undertake many tasks in order to enable a variety of processes associated with these systems, such as submission, editing and access. In this paper, we present a multifaceted evaluation initiative that aimed at the redesign of University of Patras’ institutional repository, namely ‘Nemertes’. ‘Nemertes’ is operating on a DSpace installation and the ‘Theses and Dissertations’ collection was placed at the center of evaluation as the most important collection accommodated in the service. Emphasis was given to key processes held inside the repository by conducting surveys and interviews with typical classes of users. In order to collect data from these sources three different studies were held. First the quality of Submission process inside the physical and the digital space was evaluated through a questionnaire survey, which was addressed to people who had earlier submitted in the ‘Theses and Dissertation’ collection. Secondly, the information retrieval processes and the interface were evaluated by Human-Computer Interaction savvy students using the usability heuristics principles. Finally, the Editing processes and the quality of the delivery of services were assessed through interviews with the librarians that support the service. The findings of these studies point to areas that the system can be improved and help to eliminate the barriers that prohibit the service to be upgraded and host new collections. The areas identified concern both the way of delivering the service and the operation of the system. While the contextual parameters make the generalization of the findings about the service more ambiguous, the findings concerning the system performance and the interface intuitiveness validate the results of previous studies, such as the case of terminology, the affordances and the effectiveness of search interfaces. It is anticipated that the findings of the study can be further exploited by organizations with similar repository services and technological infrastructures.
