This article summarizes the methodology and findings of the Online Catalogue and Repository Interoperability Study (OCRIS), a project recently carried out by the Centre for Digital Library Research at the University of Strathclyde, funded by the Joint Information Systems Committee (JISC). In the context of the Online Public Access Catalogs (OPAC) and the recent development of the Institutional Repository (IR) within Higher Education Institutions in the United Kingdom, it considers issues of metadata quality, name authority control, and standardized subject headings, as well as departmental and institutional workflows. It also considers duplication and scope overlap within institutions with more than one IR.  相似文献

Accessing interlibrary loan requests from various resource-sharing software systems through a single interface has long been a promise of vendors—a promise not often implemented. Our region of New York State chose VDX for its hundreds of libraries, while the State University of New York at New Paltz, the major lender, is a participant in OCLC via ILLiad. Our staff required training and updates for both systems. This article describes our successful efforts to implement interoperability and the steps and missteps encountered to achieve compatibility between VDX and ILLiad.  相似文献

SUMMARY

The translation into French of the Encoded Archival Context (EAC) DTD tag library has been in progress for a few months. It is being carried out by a group of experts gathered by AFNOR, the French national standards agency. The main goal of this group is to foster the interoperability of authority data between archives, libraries and museums, and the translation work provides an opportunity to think about the choices for standardization that underlie the EAC DTD, particularly in relation to ISAAR(CPF). It is also an excellent way of gaining familiarity with the DTD and thereby answering the need of French information specialists to increase their competencies in the structuring of digital documents and data modeling. After explaining the standardization context in which the group is working, a few major themes in its thinking will be presented, in the hope of encouraging greater international cooperation in this field.  相似文献

In this article, we present the characteristics and the design of a modular personalized multimedia testing tool based fully on XML learning specifications. Personalization is based on the characteristics of the individual learners, thus the testing paths are tailored to their needs and goals. The system maintains learner profiles rich in content from which diverse information can be elicited and presented to educators to help them understand their learners. At the end of the article, specific use cases are discussed and the educational advantages are discussed on the basis of an evaluative study.  相似文献

In the current socio-economic environment, to face challenges such as the emergence of new technologies, globalisation and increasing demands from their clients it is inevitable that enterprises will collaborate with others and progressively shift their boundaries. In this context, interoperability has become a prerequisite in the jigsaw of such collaboration. By definition, it is entities’ ability to work together as an organisation. This ability spans a wide range of aspects, embracing both technical and business issues. Over the past decade, both the concept and the context of interoperability have been extended from a largely IT-focused domain to a business-focused domain and the evaluation of interoperability has become a rising concern. An increasing number of studies have concentrated on not just digital but business aspects of human behaviour in the social environment. In general, the wider application domain is the assessment of the interoperability of information systems and processes in any organisation (especially medium and large) that needs multiple processes to interact effectively.To deal with such concerns and pave the way to achievement of more effective collaborative goals in business, the concept of interoperability has been adopted to measure the efficiency and productivity of information systems’ integration. More than twenty approaches have so far been adopted to evaluate this interoperability, however most are unable to assess it at the higher levels, such as at the pragmatic, process and social levels. Hence, we have conducted a three-phase study. Phase 1 reviewed existing interoperability evaluation approaches. To prove the concept, phase 2 proposed the concept of semiotic interoperability and its application to healthcare information systems. This article reports on the third phase of the study, a proposed framework with a group of metrics to measure interoperability from a new perspective – a semiotics perspective. The framework is named the Semiotic Interoperability Evaluation Framework (the SIEF) and has the ability to analyse, measure and assess the interoperability among business processes. The metrics derive from a feasibility study to investigate several interoperability barriers at a hospital. Next, the SIEF was applied in a case study and a detailed interoperability evaluation was conducted.  相似文献
