Abstract

FRBR (Functional Requirements for Bibliographic Records) ist ein logisches Denkmodell für bibliographische Datensätze, welches zur benutzerfreundlicheren Gestaltung von Browsing in Online-Bibliothekskatalogen herangezogen werden kann. Im Österreichischen Bibliothekenverbund (OBV) werden bibliographische Datensätze nach den Regeln für die alphabetische Katalogisierung in wissenschaftlichen Bibliotheken (RAK-WB) erstellt und liegen im Datenformat MAB2 (Maschinelles Austauschformat für Bibliotheken) vor. Mit der Software Primo von Ex Libris, die 2009 implementiert wurde, besteht die Möglichkeit bibliographische Datensätze für die Anzeige neu aufzubereiten. Wie ausgehend von MAB2-Daten eine möglichst FRBR-konforme Datenpräsentation in Primo geleistet werden kann und welche Probleme sich dabei ergeben, ist die zentrale Fragestellung dieser Master Thesis. Exemplarisch dargestellt wird dies anhand von Datensätzen des Österreichischen Bibliothekenverbundes zu Franz Kafkas "Der Process". Im Fokus stehen drei Aspekte, welche im Zusammenhang mit FRBR, MAB2 und Primo als besonders problematisch und diskussionswürdig erscheinen: das Konzept des "Werkes", Expressionen als praxistaugliche Entitäten und Aggregate bzw. mehrbändig begrenzte Werke. Nach einer Einführung in das FRBR-Modell wird versucht einen idealen FRBRBaum zu Kafkas "Der Process" in seinen unterschiedlichen Ausprägungen (Übersetzungen, Verfilmungen, Textvarianten, Aggregate etc.) darzustellen: Schon hier werden erste Grenzen des Modells sichtbar. Daran anschließend werden Datensätze des OBV einer Analyse unterzogen, um die FRBRTauglichkeit von MAB2 und die Möglichkeit der FRBR keys in Primo zu beleuchten. Folgende Einschränkungen wurden deutlich: Die derzeitige Herangehensweise und Praxis der Formalerschließung ist nicht auf FRBR vorbereitet. Die vorliegenden Metadaten sind zu inkonsistent, um ein maschinelles Extrahieren für eine FRBR-konforme Datenpräsentation zu ermöglichen. Die Möglichkeiten des Werkclusterings und der Facettierung in Primo bieten darüber hinaus zwar einen Mehrwert für das Browsing in Trefferlisten, jedoch nur bedingt im FRBR-Sinne.

Abstract

Resource Description & Access (RDA) is intended to provide a flexible and extensible framework that can accommodate all types of content and media within rapidly evolving digital environments while also maintaining compatibility with the Anglo-American Cataloguing Rules, 2nd edition (AACR2). The cataloging community is grappling with practical issues in navigating the transition from AACR2 to RDA; there is a definite need to evaluate major subject areas and broader themes in information organization under the new RDA paradigm. This article aims to accomplish this task through a thorough and critical review of the emerging RDA literature published from 2005 to 2011. The review mostly concerns key areas of difference between RDA and AACR2, the relationship of the new cataloging code to metadata standards, the impact on encoding standards such as Machine-Readable Cataloging (MARC), end user considerations, and practitioners' views on RDA implementation and training. Future research will require more in-depth studies of RDA's expected benefits and the manner in which the new cataloging code will improve resource retrieval and bibliographic control for users and catalogers alike over AACR2. The question as to how the cataloging community can best move forward to the post-AACR2/MARC environment must be addressed carefully so as to chart the future of bibliographic control in the evolving environment of information production, management, and use.

Abstract

Purpose - Bibliographic records should now be used in innovative end-user applications that enable users to learn about, discover and exploit available content, and this information should be interpreted and reused also beyond the library domain. New conceptual models such as FRBR offer the foundation for such developments. The main motivation for this research is to contribute to the adoption of the FRBR model in future bibliographic standards and systems, by analysing limitations in existing bibliographic information and looking for short- and long-term solutions that can improve the data quality in terms of expressing the FRBR model. Design/methodology/approach - MARC records in three collections (BIBSYS catalogue, Slovenian National Bibliography and BTJ catalogue) were first analysed by looking at statistics of field and subfield usage to determine common patterns that express FRBR. Based on this, different rules for interpreting the information were developed. Finally typical problems/errors found in MARC records were analysed. Findings - Different types of FRBR entity-relationship structures that typically can be found in bibliographic records are identified. Problems related to interpreting these from bibliographic records are analyzed. Frbrisation of consistent and complete MARC records is relatively successful, particularly if all entities are systematically described and relationships among them are clearly indicated. Research limitations/implications - Advanced matching was not used for clustering of identical entities. Practical implications - Cataloguing guidelines are proposed to enable better frbrisation of MARC records in the interim period, before new formats are developed and implemented. Originality/value - This is the first in depth analysis of manifestations embodying several expressions and of works and agents as subjects.

Abstract

Integration of library data into the Linked Data environment is a key issue in libraries and is approached on the basis of interoperability between library data conceptual models. Achieving interoperability for different representations of the same or related entities between the library and cultural heritage domains shall enhance rich bibliographic data reusability and support the development of new data-driven information services. This paper aims to contribute to the desired interoperability by attempting to map core semantic paths between the BIBFRAME and EDM conceptual models. BIBFRAME is developed by the Library of Congress to support transformation of legacy library data in MARC format into linked data. EDM is the model developed for and used in the Europeana Cultural Heritage aggregation portal.

Abstract

One of the big challenges facing academic libraries today is to increase the relevance of the libraries to their user communities. If the libraries can increase the visibility of their resources on the open web, it will increase the chances of the libraries to reach to their user communities via the user's first search experience. BIBFRAME and library Linked Data will enable libraries to publish their resources in a way that the Web understands, consume Linked Data to enrich their resources relevant to the libraries' user communities, and visualize networks across collections. However, one of the important steps for transitioning to BIBFRAME and library Linked Data involves crosswalks, mapping MARC fields and subfields across data models and performing necessary data reformatting to be in compliance with the specifications of the new model, which is currently BIBFRAME 2.0. This article looks into how the Library of Congress has mapped library bibliographic data from the MARC format to the BIBFRAME 2.0 model and vocabulary published and updated since April 2016, available from http://www.loc.gov/bibframe/docs/index.html based on the recently released conversion specifications and converter, developed by the Library of Congress with input from many community members. The BIBFRAME 2.0 standard and conversion tools will enable libraries to transform bibliographic data from MARC into BIBFRAME 2.0, which introduces a Linked Data model as the improved method of bibliographic control for the future, and make bibliographic information more useful within and beyond library communities.
