An Architecture for Multischeming in Digital Libraries

Journal of Information Science Theory and Practice, 2015

This paper describes qualities of a library classification system that are commonly discussed in the LIS tradition and literature, and explains such a system's three main functions, namely knowledge mapping, information retrieval, and shelf arrangement. In this vein, the paper states the functional requirements of bibliographic classifications, which broadly are subject collocation and facilitation of browsing the collection. It explains with details the components of a library classification system and their functions. The major components are schedules, notations, and index. It also states their distinguished features, such as generalia class, form divisions, book numbers, and devices for number synthesis which are not required in a knowledge classification. It illustrates with examples from the WebDewey good examples of added features of an online library classification system. It emphasizes that institutional backup and a revision machinery are essential for a classification to survive and remain relevant in the print and e-environment.

DELOS is an interdisciplinary EU FP6 Network of Excellence with a broad vision: Future digital libraries should enable any citizen to access human knowledge any time and anywhere, in a friendly, multi-modal, efficient and effective way. The main objective of DELOS is to define and conduct a joint program of activities in order to integrate and coordinate the ongoing research activities of the research teams in the field of digital libraries for the purpose of developing next generation digital library technologies.

This paper describes a digital library architecture and implementation that is configurable, extensible and dynamic in the way it presents content and in the services it provides. The design manifests itself as a network of modules that communicate in terms of XML messages. All modules characterize the functionality they implement in response to a “describe yourself” message, and can transform messages using XSLT to support different levels of configurability. Traditional library values such as backwards compatibility and multiplatform operation are combined with the ability to add new collections and services adaptively. The paper describes the new design and shows how it can be used to build four different digital library systems. We conclude by showing how the design fits existing interoperability frameworks.

Digital Library (DL) interoperability requires addressing a variety of issues associated with functionality. We report on the analysis and solutions identified by the Functionality Working Group of the DL.org project during its deliberations on DL interoperability. Ultimately, we hope that work based on our perspective will lead to improved architectures and software, as well as to greater interoperability, for next-generation DL systems.

ÐThe application of an object orientated (OO) methodology to the design of a platform for heterogeneous Digital Libraries with multiagent technologies is demonstrated. Emphasis is placed on maximizing the autonomy of the query processing activity. The Fusion OO paradigm is specifically employed as the basis for the design process due to the significance attributed to the development of object interfaces under static and dynamic conditions. Finally, characteristics of the proposed Domain Index Server (DIS) platform are contrasted with those of an alternative platform (UMDL) by way of the respective Fusion descriptions. This identifies a different emphasis to the interface design between objects in the two platforms: The DIS system uses more dynamic links while the UMDL system focuses on permanent and constant links. Simulation of the two platforms provides performance data that demonstrates the higher capacity of the DIS scheme. Index TermsÐObject-orientated design, digital libraries, heterogeneous database systems, multiagent systems.

THENOTION OF THE CLASSIFICATION SCHEME as a transitional element or "boundary object" offers an alternativc to the more traditional approach that views classification as an organizational structure imposed upon a body of knowledge to facilitate access within a universal and frequently static framework. Recognition of the underlying relationship between user access and the collective knowledge structures that are the basis for knowledge production indicates the dynamic role of classification in supporting coherence and articulation across heterogeneous contexts. To this end, it is argued that the library should be an active participant in the production of knowledge, and that this role can be effected by the development of classificatory structures that can support the needs of a diverse information ecology consisting of a complex web of interacting agents, users, and technologies. Within such an information ecology, a classificatory structure cannot follow a one-size-fits-all paradigm but must evolve in cooperative interaction between librarians and their user groups.

Athens University recently initiated a digital collection development project to provide enhanced educational capabilities. Collections vary in terms of the material included and the requirements imposed by potential users. Collections are developed by cataloguers and researchers working in specific university libraries, while all of them are administered by the Libraries Computer Centre. In order to simplify collection management and promote collection interoperability, a common digital library platform should be employed to support all collections. To deal with the extended requirements imposed, it was decided to extend an open source digital library system, rather than using "out of the box" software. In this paper, we present the criteria used to choose a DL system for developing the University's digital collections and discuss the prototype version of the system built using Fedora and DSpace. In order to evaluate them, the Folklore Collection was used as an example. Conclusions drawn from their comparison and the proposed integrated DL architecture based on Fedora are also presented.

Conference companion on Human factors in computing systems common ground - CHI '96, 1996

In this paper we describe an interface to a heterogeneous digital library. The interface is designed with the following goals in mind: to support user tasks, to smoothly integrate the results of many services, to handle services of widely-varying time scales, to be extensible, and to support sharing and reuse. We discuss each of these goals, and then describe a working prototype interface.

With the increased use of information and communication technology for information processing, search and retrieval, newer knowledge organisation tools are being developed. These include taxonomies, folksonomies, ontologies, etc. This chapter reviews literature that deals with these knowledge organisation tools, covering various aspects such as their development, use and integration. The emergence of various knowledge organisation tools also created the need for developing interoperable mechanisms. As a result of emergence interoperability, literature on this topic is also increasing, which is reviewed in this chapter.
