Abstract

- Zielsetzung - Bevor mit der Ausarbeitung einer Lösung für originalschriftliche Eingaben im Österreichischen Bibliothekenverbund begonnen werden konnte, waren bestimmte Rahmenbedingungen festzulegen. Hohe Priorität sollte einer ökonomischen Katalogisierung eingeräumt werden (effiziente Arbeitsabläufe, einfache und übersichtliche Kategorienstrukturen, unterstützende Satzschablonen). Auch von systembibliothekarischer und systemadministrativer Seite her sollte der Aufwand möglichst gering gehalten werden (z.B. Anpassungsumfang bei der Parametrisierung, Anzahl der zu ändernden Tabellen). Weiters wurden Aleph 500-Anwender, die außerhalb des Österreichischen Bibliothekenverbundes das MAB-Format verwenden, in die Diskussion miteingebunden, um eine möglichst einheitliche Lösung zu finden (Import- und Exportschnittstellen müssten dann von der Herstellerfirma Ex Libris nur einmal adaptiert werden). Außerdem wurde vorerst festgelegt, dass die neu hinzukommenden originalschriftlichen Texte lediglich für die Anzeige dienen sollten. Indexierung und Retrieval sind hingegen hier nicht vorgesehen. Basis für die zu implementierende Lösung war nahe liegender Weise der vorliegende MAB-Entwurf (schließlich ist das im Österreichischen Bibliothekenverbund verwendete Internformat bis auf einige kleinere Adaptionen und eine durchgängige Subfieldstruktur nahezu ident mit dem MABFormat). Dennoch sahen wir keine Notwendigkeit, uns um jeden Preis an diesen Entwurf halten zu müssen, falls er sich als unnötig kompliziert und ineffizient erweisen sollte.

Cataloguing artworks relies on the availability of classification schemes, often represented by hierarchical thesauri. Comments on the limitations of current practices and tools and proposes a new approach for the cooperative production of multilingual and multicultural classification schemes exploiting some features of the oncoming Extensible Markup Language based Web

Abstract

This paper describes an experiment exploring the hypothesis that innovative application of the Functional Require-ments for Bibliographic Records (FRBR) principles can complement traditional bibliographic resource discovery systems in order to improve the user experience. A specialized service was implemented that, when given a plain list of results from a regular online catalogue, was able to process, enrich and present that list in a more relevant way for the user. This service pre-processes the records of a traditional online catalogue in order to build a semantic structure following the FRBR model. The service also explores web search features that have been revolutionizing the way users conceptualize resource discovery, such as relevance ranking and metasearching. This work was developed in the context of the TELPlus project. We processed nearly one hundred thousand bibliographic and authority records, in multiple languages, and originating from twelve European na-tional libraries. This paper describes the architecture of the service and the main challenges faced, especially concerning the extraction and linking of the relevant FRBR entities from the bibliographic metadata produced by the libraries. The service was evaluated by end users, who filled out a questionnaire after using a traditional online catalogue and the new service, both with the same bibliographic collection. The analysis of the results supports the hypothesis that FRBR can be implemented for re-source discovery in a non-intrusive way, reusing the data of any existing traditional bibliographic system.

Abstract

This paper proposes the use of the Unified Modeling Language (UML) as a language for modelling ontologies for Web resources and the knowledge contained within them. To provide a mechanism for serialising and processing object diagrams representing knowledge, a pair of XSI-T stylesheets have been developed to map from XML Metadata Interchange (XMI) encodings of class diagrams to corresponding RDF schemas and to Java classes representing the concepts in the ontologies. The Java code includes methods for marshalling and unmarshalling object-oriented information between in-memory data structures and RDF serialisations of that information. This provides a convenient mechanism for Java applications to share knowledge on the Web

Abstract

This article explores recent discussions about appropriate mark-up conventions for library information intended for use on the World Wide Web. In particular, the question of whether the MARC 21 format will continue to be useful and whether the time is right for a full-fledged conversion effort to XML is explored. The author concludes that the MARC format will be relevant well into the future, and its use will not hamper access to bibliographic information via the web. Early XML exploratory efforts carried out at the Stanford University's Lane Medical Library are reported on. Although these efforts are a promising start, much more consultation and investigation is needed to arrive at broadly acceptable standards for XML library information encoding and retrieval.

Abstract

Es steht uns eine praktisch unbegrenzte Menge an Informationen über das World Wide Web zur Verfügung. Das Problem, das daraus erwächst, ist, diese Menge zu bewältigen und an die Information zu gelangen, die im Augenblick benötigt wird. Das überwältigende Angebot zwingt sowohl professionelle Anwender als auch Laien zu suchen, ungeachtet ihrer Ansprüche an die gewünschten Informationen. Um dieses Suchen effizienter zu gestalten, gibt es einerseits die Möglichkeit, leistungsstärkere Suchmaschinen zu entwickeln. Eine andere Möglichkeit ist, Daten besser zu strukturieren, um an die darin enthaltenen Informationen zu gelangen. Hoch strukturierte Daten sind maschinell verarbeitbar, sodass ein Teil der Sucharbeit automatisiert werden kann. Das Semantic Web ist die Vision eines weiterentwickelten World Wide Web, in dem derart strukturierten Daten von so genannten Softwareagenten verarbeitet werden. Die fortschreitende inhaltliche Strukturierung von Daten wird Semantisierung genannt. Im ersten Teil der Arbeit sollen einige wichtige Methoden der inhaltlichen Strukturierung von Daten skizziert werden, um die Stellung von Ontologien innerhalb der Semantisierung zu klären. Im dritten Kapitel wird der Aufbau und die Aufgabe des CIDOC Conceptual Reference Model (CRM), einer Domain Ontologie im Bereich des Kulturerbes dargestellt. Im darauf folgenden praktischen Teil werden verschiedene Ansätze zur Verwendung des CRM diskutiert und umgesetzt. Es wird ein Vorschlag zur Implementierung des Modells in XML erarbeitet. Das ist eine Möglichkeit, die dem Datentransport dient. Außerdem wird der Entwurf einer Klassenbibliothek in Java dargelegt, auf die die Verarbeitung und Nutzung des Modells innerhalb eines Informationssystems aufbauen kann.
