Abstract

The Bibliographic Framework Transition Initiative is an undertaking by the Library of Congress and the community to better accommodate future needs of the library community. A major focus of the initiative will be to determine a transition path for the MARC 21 exchange format to more Web based, Linked Data standards. Zepheira and The Library of Congress are working together to develop a Linked Data model, vocabulary and enabling tools / services for supporting this Initiative. BIBFRAME.ORG is a central hub for this effort.

Abstract

Using new communication technologies libraries must face continuously new questions, possibilities and expectations. This study discusses library-related aspects of our electronic era and how computer-related data formats affect bibliographic dataprocessing to give a summary of the most important results. First bibliographic formats for the exchange of bibliographic and related information in the machine-readable form between different types of computer systems were created more than 30 years ago. The evolution of information technologies leads to the improvement of computer systems. In addition to the development of computers and media types Internet has a great influence on data structure as well. Since the introduction of MARC bibliographic format, technology of data exchange between computers and between different computer systems has reached a very sophisticated stage and has contributed to the creation of new standards in this field. Today libraries work with this new infrastructure that induces many challenges. One of the most significant challenges is moving from a relatively homogenous bibliographic environment to a diverse one. Despite these challenges such changes are achievable and necessary to exploit possibilities of new metadata and technologies like the Internet and XML (Extensible Markup Language). XML is an open standard, a universal language for data on the Web. XML is nearly six-years-old standard designed for the description and computer-based management of (semi)-structured data and structured texts. XML gives developers the power to deliver structured data from a wide variety of applications and it is also an ideal format from server-to-server transfer of structured data. XML also isn't limited for Internet use and is an especially valuable tool in the field of library. In fact, XML's main strength - organizing information - makes it perfect for exchanging data between different systems. Tools that work with the XML can be used to process XML records without incurring additional costs associated with one's own software development. In addition, XML is also a suitable format for library web services. The Department of Computer-related Graphic Design and Library and Information Sciences of Debrecen University launched the BDML (Bibliographic Description Markup Language) development project in order to standardize bibliogrphic description with the help of XML.

"Die Mitglieder der Arbeitsgruppe Regionalbibliographie in der Arbeitsgemeinschaft der Regionalbibliotheken (DBV Sektion 4) haben auf ihrer Jahrestagung am 22. und 23. April 2002 in Bautzen einen etwaigen Umstieg von RAK auf AACR2 beraten und sich einstimmig dagegen ausgesprochen. - Begründung - Der personelle, technische und finanzielle Aufwand für den Umstieg wäre für die Landes- und Regionalbibliographien gewaltig. Diejenigen Bibliographien, die ihre eigenen Datenbanken unterhalten, müssten diese sowohl vollständig EDV-technisch (z.B. hinsichtlich des Datenformats) anpassen als auch sämtliche Änderungen (z.B. bei Zeitschriftenaufnahmen, bei der Ansetzung von Körperschaften) nachführen. Dies ist umso schwerwiegender, als nicht alle Bibliographie- Datenbanken über entsprechende eigene Normdateien verfügen. Alle Landes- und Regionalbibliographien, also auch diejenigen, die in die Verbunddatenbanken integriert sind, wären überdies vom zusätzlichen Schulungsaufwand für das neue Regelwerk sowie von Revisionsarbeiten an den Normdateien betroffen. Weitere Nachteile wären Inkonsistenzen im Datenbestand bzw. Qualitätsverluste bei der Konvertierung der Altdaten. Diesen schwerwiegenden Nachteilen steht kein ersichtlicher Vorteil bei Erstellung oder Benutzung der Landes- und Regionalbibliographien gegenüber: Der Rationalisierungseffekt ist unbedeutend, da in Regionalbibliographien ganz überwiegend unselbstständige deutschsprachige Titel verzeichnet werden, für die keine Katalogisate aus AACR-Ländern genutzt werden können. Auch für die Benutzer der Datenbanken steht keine Verbesserung der Rechercheergebnisse zu erwarten. Die Landes- und Regionalbibliographien sehen sich derzeit einer Vielzahl von Aufgaben und neuen Herausforderungen gegenüber, die sie mit bestenfalls stagnierendem Personalstand zu erfüllen haben: Neben einer stetig wachsenden Titelzahl sind dies z.B. die neuen Publikationsformen im WWW, der Aufbau eines gemeinsamen Suchinstruments ("Virtuelle Deutsche Landesbibliographie° in KVK-Technik) und die Integration der noch konventionell vorliegenden älteren Bibliographienachweise in die Datenbanken. In dieser Situation wäre es kontraproduktiv, wenn enorme Ressourcen für einen Regelwerks- und Formatwechsel ohne praktischen Nutzen abgezogen würden. Die AG Regionalbibliographie lehnt daher einen Umstieg auf AACR2 ab. Sie empfiehlt stattdessen, das bestehende Regelwerk weiterzuentwickeln sowie alternative und zeitgemäße Methoden zu erarbeiten, um die internationale Zusammenarbeit zu verbessern (z.B. durch das Projekt "Virtuelle internationale Normdatei")."
