DRIVER Technology Watch Report

This report is part of the Discovery Workpackage (WP4) and is the third report out of four deliverables. The objective of this report is to give an overview of the latest technical developments in the world of digital repositories, digital libraries and beyond, in order to serve as theoretical and practical input for the technical DRIVER developments, especially those focused on enhanced publications. This report consists of two main parts, one part focuses on interoperability standards for enhanced publications, the other part consists of three subchapters, which give a landscape picture of current and surfacing technologies and communities crucial to DRIVER. These three subchapters contain the GRID, CRIS and LTP communities and technologies. Every chapter contains a theoretical explanation, followed by case studies and the outcomes and opportunities for DRIVER in this field

Improving Knowledge Retrieval in Digital Libraries Applying Intelligent Techniques

Nowadays an enormous quantity of heterogeneous and distributed information is stored in the digital University. Exploring online collections to find knowledge relevant to a user’s interests is a challenging work. The artificial intelligence and Semantic Web provide a common framework that allows knowledge to be shared and reused in an efficient way. In this work we propose a comprehensive approach for discovering E-learning objects in large digital collections based on analysis of recorded semantic metadata in those objects and the application of expert system technologies. We have used Case Based-Reasoning methodology to develop a prototype for supporting efficient retrieval knowledge from online repositories. We suggest a conceptual architecture for a semantic search engine. OntoUS is a collaborative effort that proposes a new form of interaction between users and digital libraries, where the latter are adapted to users and their surroundings

ALT-SURF seminar: ePortfolios and Digital Repositories, 22 and 23 April 2004, Edinburgh UK

ALT (Association for Learning Technology) and SURF (collaborative organisation for IT innovation in Dutch HE) have similar goals and started working together in 1999. In 2001 they signed a Memorandum of Understanding to bring together learning technologists from the UK and the Netherlands in a variety of exchange activities. Sharing experiences and views internationally between peers proved to be an excellent way to learn new things, find inspiration to meet joint challenges and engage in healthy reflection. ALT and SURF organised mutual study visits (50 Dutch learning technologists visited universities in the UK in 2002 and 40 UK colleagues visited Dutch institutes in 2003), joint conferences and seminars, and a expert study trip to Australia (8 UK and 8 Dutch experts visited 14 institutes in 2002). SURF and ALT reported on these in presentations and publications. A new activity is the joint working seminar, where a specific theme can be discussed by experts in the field with the purpose of describing in a so-called ‘briefing paper’ the current state of affairs, the underlying beliefs, hopes and desired situation, and possible ‘next steps’ in joint conceptualisation and/or developing activities. In the process of composing the briefing papers differences between the countries will surface, e.g. organisational, cultural or political. The themes are therefore not isolated topics but seen as developments within a context. The first joint ALT-SURF working seminar took place in April 2004 in Edinburgh, immediately following an ALT spring conference, and addressed two related topics: e-(or Digital) Portfolios and Digital Repositories. The aim was to establish working relationships between experts in both countries through discussion and collaborative writing of briefing papers aimed at experts, researchers, managers and policy makers. The objectives of the working seminar were threefold: • describe the basic belief that leads to so much energy being put into these concepts • outline current thinking in ePortfolios and Digital repositories as a common reference point for deeper understanding • devise a roadmap to meet required conditions to further develop ePortfolios and Digital Repository concepts and use. This report is the result of that seminar, namely a briefing paper on ePortfolios and another on Digital Repositories. In the papers the potential and ultimate goal of using ePortfolios and Digital Repositories for learning and teaching is outlined; the current state of achievements is described, and thirdly the briefing paper concludes with desired next steps to reach the ultimate goals, what conditions need to be in place, what activities need to be set in motion. The papers highlight any apparent differences in approaches between UK and Netherlands as well as opportunities for future collaboration. SURF and ALT will use the conclusions and suggestions as input for joint future development and networking activities

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

Cloudworks: social networking for learning design

Why do some social networking services work and others fail? Can we apply the best of Web 2.0 principles to an educational context? More specifically can we use this as a means of shifting teaching practice to a culture of sharing learning ideas and designs? Can we harness the potential of technologies to create more engaging learning experiences for students? These are the key questions this paper addresses. We describe how we are using the concept of 'object-orientated social networking' to underpin the creation of a social networking tool, Cloudworks, for sharing learning ideas and designs

Linked education: interlinking educational resources and the web of data

Research on interoperability of technology-enhanced learning (TEL) repositories throughout the last decade has led to a fragmented landscape of competing approaches, such as metadata schemas and interface mechanisms. However, so far Web-scale integration of resources is not facilitated, mainly due to the lack of take-up of shared principles, datasets and schemas. On the other hand, the Linked Data approach has emerged as the de-facto standard for sharing data on the Web and offers a large potential to solve interoperability issues in the field of TEL. In this paper, we describe a general approach to exploit the wealth of already existing TEL data on the Web by allowing its exposure as Linked Data and by taking into account automated enrichment and interlinking techniques to provide rich and well-interlinked data for the educational domain. This approach has been implemented in the context of the mEducator project where data from a number of open TEL data repositories has been integrated, exposed and enriched by following Linked Data principles

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

Computer-based library or computer-based learning?

Traditionally, libraries have played the role of repository of published information resources and, more recently, gateway to online subscription databases. The library online catalog and digital library interface serve an intermediary function to help users locate information resources available through the library. With competition from Web search engines and Web portals of various kinds available for free, the library has to step up to play a more active role as guide and coach to help users make use of information resources for learning or to accomplish particular tasks. It is no longer sufficient for computer-based library systems to provide just search and access functions. They must provide the functionality and environment to support learning and become computer-based learning systems. This paper examines the kind of learning support that can be incorporated in library online catalogs and digital libraries, including 1) enhanced support for information browsing and synthesis through linking by shared meta-data, references and concepts; 2) visualization of related information; 3) adoption of Library 2.0 and social technologies; 4) adoption of Library 3.0 technologies including intelligent processing and text mining
