Abstract

Purpose - To research a resource description framework (RDF) based digital library system that facilitates digital resource management and supports knowledge management for an interoperable information environment. Design/methodology/approach - The paper first introduces some of issues with metadata management and knowledge management and describes the needs for a true interoperable environment for information transferring across domains. A journal delivery application has been implemented as a concept-proof project to demonstrate the usefulness of RDF in digital library systems. Findings - The RDF-based digital library system at the University of Arizona Libraries provides an easy way for digital resource management by integrating other applications regardless of metadata formats and web presence. Practical implications - A journal delivery application has been running in the RDF-based digital library system since April 2005. An electronic theses and dissertation application will be handled by the same system. Originality/value - The paper suggests to use RDF, the semantic web technology, as a new approach to facilitate knowledge management and metadata management. Using RDF technology brings new ways to manage and discover information for libraries.

Abstract

Large, data-rich organizations have tremendously large collections of digital objects to be "repurposed," to respond quickly and economically to publishing, marketing, and information needs. Some management typically assume that a content management system, or some other technique such as OWL and RDF, will automatically address the workflow and technical issues associated with this reuse. Four case studies show that the sources of some roadblocks to agile repurposing are as much managerial and organizational as they are technical in nature. The review concludes with suggestions on how digital object repurposing can be integrated given these organizations' structures.

Abstract

Das Semantic Web als logische Fortführung des bestehenden Internets wird prosperieren. sobald entsprechende Werkzeuge zur Erstellung von entsprechendem Content auf Basis weithin akzeptierter Metadaten-Schemata vorliegen. Mit RDF liegt ein universell einsetzbares Format vor, das sich generell für die Definition solcher Schemata eignet, um Inhalte hinsichtlich ihrer Bedeutung in maschinell lesbarer Form zu beschreiben, sprich: zu annotieren und mit semantischer Information anzureichern. Content Management Systeme (CMS) sind eine wesentliche Technologie für die Bereitstellung von Online-Diensten bzw. zur Aufbereitung und Verwaltung digitaler Inhalte speziell für das Web bzw. für Firmenintranets. Insofern wird von CMSEntwicklern immer größeres Augenmerk auf Semantic Web-Technologien gelegt, was mit der Möglichkeit beginnt, Inhalte wohl strukturiert einpflegen zu können, ohne dabei den Redaktionsaufwand übermäßig zu strapazieren. Dieser Beitrag zeigt. welche Eigenschaften ein CMS mitzubringen hat, um Semantic Web-taugliche Inhalte generieren und verwalten zu können und geht auf die Vorteile und Möglichkeiten ein, die daraus sowohl Content-Providern, Redakteuren als auch Benutzern erwachsen.

Abstract

Purpose - The purpose of this article is to describe a new use of technology to improve users' access to electronic resources. Design/methodology/approach - Describes the use of guided searches in a library gateway to shorten the pathway to information for library users. Findings - Guided search forms can be constructed for both databases and catalogs using HTML and JavaScript. They are a useful alternative to vendor-provided search interfaces, especially for inexperienced users. Research limitations/implications - This paper focuses on the technical issues involved in creating guided searches. It does not address usability testing and a detailed comparison of effectiveness with vendor-provided interfaces. Practical implications - Working with tools already in hand libraries can improve the accessibility of electronic resources by crafting simpler user interfaces. Originality/value - The paper shows libraries how they can leverage their investment in databases and the catalog not only to make them more useful to their user communities, but to bring them more in tune with the expectations of users who have grown up with the web.

Abstract

Different classification schemes may be used for web indexing. The authors analyze three weblogs (Biblioatipici, Letture and Andrea Marchitelli's blog) to demonstrate that different contents may be classified using the appropriate scheme. Biblioatipici is a weblog about temporary workers in libraries and Italian documentation centres indexed with a faceted scheme, home made by authors. Lecture, a diary about reading and books, is indexed by DDC. Marchitelli's blog about digital libraries and open access, is indexed by JITA, the scheme used for indexing eprints in some different open archives. The three applications are presented starting from the most complex scheme (i.e. the faceted one) to the simple but least functional (JITA), passing through a traditional bibliographic classification scheme, the Dewey Decimal Classification. The analysis demonstrates that different web contents can efficiently be classified with different schemes. In particular, with the facets one (Biblioatipici) the indexer is able to generate the needed classes in the indexing phase. Moreover with a small number of facets and foci one can obtain an exponential number of classes. Finally, one of the advantages for the user is that the faceted scheme allows multiple accesses on the basis of different information requirements, in addition to being coherent and intuitive. DDC scheme can be more suitable than the first web pages or blogs performing a sort of digital library. In this case in fact the DDC scheme constitutes a consolidated classification standard, widespread in a huge quantity of libraries and the use of a different scheme might get confusion. JITA scheme, finally, can find a huge applicability in web pages (or blogs) in LIS field showing several advantages: it's very simple and essentially pragmatic, intuitive and coherent. It's a conservative scheme because it is structurally closed, in fact it does not allow the classifier to insert new LCS's categories. If, from a certain point of view, this is a disadvantage, vice versa this feature is really useful because you get a complete matching between classes of all the web pages implemented with it.
