Multimedia repositories in learning and teaching – lessons from the MIDESS Project

The MIDESS project brought together 4 UK universities to explore the management of digitised content through the development of a digital repository infrastructure. The project focused on multimedia materials in particular and looked at how support can be provided for their use in a learning and research context and how resources can be shared both within and between institutions. Three repositories were implemented, using Fedora, DSpace and Digitool respectively. Material suitable for ingest was identified and the dialogue with academic partners in each institution helped clarify not only the complexity of the interactions required but also the value of the repository in supporting learning, teaching and research. Having established a repository platform within each institution, the project then explored how multimedia content could be exchanged and shared between the repositories, using OAI-PMH and METS as transport mechanisms. This paper will summarise the project’s main findings. In particular, it will address how a multimedia repository might fit into the information architecture of the university, the likely requirements for integration into an inter-institutional or national framework and some of the obstacles which can impede such integration. Scenarios will be presented illustrating how student learning can benefit from such a repository within a research-intensive university and the relationship between the repository and the VLE will be discussed

Ensuring the discoverability of digital images for social work education : an online tagging survey to test controlled vocabularies

The digital age has transformed access to all kinds of educational content not only in text-based format but also digital images and other media. As learning technologists and librarians begin to organise these new media into digital collections for educational purposes, older problems associated with cataloguing and classifying non-text media have re-emerged. At the heart of this issue is the problem of describing complex and highly subjective images in a reliable and consistent manner. This paper reports on the findings of research designed to test the suitability of two controlled vocabularies to index and thereby improve the discoverability of images stored in the Learning Exchange, a repository for social work education and research. An online survey asked respondents to "tag", a series of images and responses were mapped against the two controlled vocabularies. Findings showed that a large proportion of user generated tags could be mapped to the controlled vocabulary terms (or their equivalents). The implications of these findings for indexing and discovering content are discussed in the context of a wider review of the literature on "folksonomies" (or user tagging) versus taxonomies and controlled vocabularies

OCRIS : online catalogue and repository interoperability study. Final report

The aims and objectives of OCRIS were to: • Survey the extent to which repository content is in scope for institutional library OPACs, and the extent to which it is already recorded there; • Examine the interoperability of OPAC and repository software for the exchange of metadata and other information; • List the various services to institutional managers, researchers, teachers and learners offered respectively by OPACs and repositories; • Identify the potential for improvements in the links (e.g. using link resolver technology) from repositories and/or OPACs to other institutional services, such as finance or research administration; • Make recommendations for the development of possible further links between library OPACs and institutional repositories, identifying the benefits to relevant stakeholder groups

Extending the 5S Framework of Digital Libraries to support Complex Objects, Superimposed Information, and Content-Based Image Retrieval Services

Advanced services in digital libraries (DLs) have been developed and widely used to address the required capabilities of an assortment of systems as DLs expand into diverse application domains. These systems may require support for images (e.g., Content-Based Image Retrieval), Complex (information) Objects, and use of content at fine grain (e.g., Superimposed Information). Due to the lack of consensus on precise theoretical definitions for those services, implementation efforts often involve ad hoc development, leading to duplication and interoperability problems. This article presents a methodology to address those problems by extending a precisely specified minimal digital library (in the 5S framework) with formal definitions of aforementioned services. The theoretical extensions of digital library functionality presented here are reinforced with practical case studies as well as scenarios for the individual and integrative use of services to balance theory and practice. This methodology has implications that other advanced services can be continuously integrated into our current extended framework whenever they are identified. The theoretical definitions and case study we present may impact future development efforts and a wide range of digital library researchers, designers, and developers

Indexing standard for sharing health education multimedia resources: the Health Education Assets Library (HEAL) metadata schema

Journal ArticleHealth sciences educators are increasingly incorporating multimedia (including images, animations, and videos) into educational materials , such as PowerPoint lectures, web sites, and interactive quizzes and cases. Educators continue to "reinvent the wheel" and develop costly duplicates of multimedia resources, despite new opportunities offered by the Internet to share resources. The Health Education Assets Library (HEAL) is designed to provide health sciences educators with freely available, high quality multimedia materials to augment health sciences education. We describe an XML schema that we created to index the health sciences multimedia resources in HEAL. The metadata schema provides a common mechanism by which remotely located distributed systems may share metadata records, allowing the end user to search many collections through one interface

Object lessons : a learning object approach to e-learning for social work education

Learning objects are bite-sized digital learning resources designed to tackle the e-learning adoption problem by virtue of their scale, adaptability, and interoperability. The learning object approach advocates the creation of small e-learning resources rather than whole courses: resources that can be mixed and matched; used in a traditional or online learning environment; and adapted for reuse in other discipline areas and in other countries. Storing learning objects within a subject specific digital repository to enable search, discovery, sharing and use adds considerable value to the model. This paper explores the rationale for a learning object approach to e-learning and reflects on early experiences in developing a national learning object repository for social work education in Scotland

Development of an Online Digital Multimedia Library and Database for Medical Education

At the University of Nebraska Medical Center (UNMC), the Departments of Family Medicine, Internal Medicine, and Pediatrics in the College of Medicine teamed with Information Technology Services (ITS) and Library Services to create an online retrieval and repository system for sharing digital medical multimedia objects among health care practitioners, educators and students. A pilot launch of the system was done within the above three primary care departments. This presentation will focus on how the website structure and database structure were determined, what programming techniques and software were involved and the results of the pilot of this initiative. We will also discuss the next steps involved in expanding use of the system across other departments and colleges at UNMC
