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

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.

Abstract

This article presents an empirical study focused on a qualitative analysis of the UNIMARC format. An analysis of the structural quality of the data provided by the format is evaluated to determine its current suitability for meeting the requirements and trends in data architecture for the information network and the Semantic Web. Driven by a set of quality characteristics that identify weaknesses in the data schema that cannot be bridged by simply converting data to MARC XML or RDF/XML, we conclude that the UNIMARC format is not compliant with the current metadata schema desiderata and must be replaced.

Abstract

In response to libraries' frustration over their rich resources being invisible on the web, Zepheira, at the request of the Library of Congress, created BIBFRAME, a bibliographic metadata framework for cataloging. The model replaces MARC records with linked data, promoting resource visibility through a rich network of links. In place of formal taxonomies, a small but extensible vocabulary streamlines metadata efforts. Rather than using a unique bibliographic record to describe one item, BIBFRAME draws on the Dublin Core and the Functional Requirements for Bibliographic Records (FRBR) to generate formalized descriptions of Work, Instance, Authority and Annotation as well as associations between items. Zepheira trains librarians to transform MARC records to BIBFRAME resources and adapt the vocabulary for specialized needs, while subject matter experts and technical experts manage content, site design and usability. With a different approach toward data modeling and metadata, previously invisible resources gain visibility through linking.

Abstract

Im Jahr 2007 hat die GWLB gemeinsam mit der HAAB, der Universitätsbibliothek Johann Christian Senckenberg und mehreren Stiftungen die Königliche Gartenbibliothek Herrenhausen erworben. Neben den textuellen Materialien enthält die Bibliothek auch viele nicht-textuelle Materialien wie Herbarien, Zeichnungen und auch Gouachen mit Abbildungen von Obstsorten aus der ehemaligen Obstbaumplantage. Diese Gouachen in Mappen liegend bei der GWLB aufbewahrt. Die einzelnen Blätter tragen keine Titel, sondern sind am unteren Rand mit Bleistift durchnummeriert. Ohne die beigefügte ebenfalls durchnummerierte Liste mit Sortennamen ist keine eindeutige Zuordnung und die Nutzung somit nur eingeschränkt möglich. Die Überlegung zu einer digitalen Präsentation liegt daher nahe, denn "der ungehinderte Zugang zu elektronischen wissenschaftlich relevanten Publikationen von jedem Ort aus und zu jeder Zeit spielt in der digitalen Informationsgesellschaft eine immer bedeutendere Rolle." Oder um es drastischer zu formulieren: "Was nicht im Web ist, ist nicht in der Welt". Bevor jedoch mit der Digitalisierung begonnen werden kann, müssen einige Fragen vorab geklärt werden. Im Folgenden werden Kriterien, die bei der Planung und Durchführung von Digitalisierungsprojekten zu beachten sind, behandelt.
