datos.bne.es and MARiMbA: an insight into Library Linked Data

Purpose – Linked data is gaining great interest in the cultural heritage domain as a new way for publishing, sharing and consuming data. The paper aims to provide a detailed method and MARiMbA a tool for publishing linked data out of library catalogues in the MARC 21 format, along with their application to the catalogue of the National Library of Spain in the datos.bne.es project. Design/methodology/approach – First, the background of the case study is introduced. Second, the method and process of its application are described. Third, each of the activities and tasks are defined and a discussion of their application to the case study is provided. Findings – The paper shows that the FRBR model can be applied to MARC 21 records following linked data best practices, librarians can successfully participate in the process of linked data generation following a systematic method, and data sources quality can be improved as a result of the process. Originality/value – The paper proposes a detailed method for publishing and linking linked data from MARC 21 records, provides practical examples, and discusses the main issues found in the application to a real case. Also, it proposes the integration of a data curation activity and the participation of librarians in the linked data generation process

E-resource management and the Semantic Web : applications of RDF for e-resource discovery

Semantic Web technologies and specifications are increasingly finding applications within digital libraries and other e-resource contexts. The purpose of this chapter is to provide an introduction to some essential Semantic Web concepts and the resource description framework (RDF), a key enabling language of the Semantic Web. Applications of RDF including Dublin Core, FOAF, SKOS and RDFa will be explored with practical examples, and recent implementations of these specifications within a variety of e-resource discovery contexts will be discussed

Bibliografische Daten, Normdaten und Metadaten im Semantic Web : Konzepte der Bibliografischen Kontrolle im Wandel

Diese Veröffentlichung geht zurück auf eine Magisterarbeit (2010) im Direktstudiengang Bibliothekswissenschaft an der Humboldt-Universität zu Berlin.Die Informationsräume Bibliothek und World Wide Web (WWW) stehen vor der gleichen Herausforderung: Eine korrekte, umfassende und nutzergerechte Erschliessung ihrer Dokumente zu leisten. Eine Lösung aus beiden Perspektiven wäre eine einfache und universelle Ressourcenbeschreibung, die implizit generiert wird. Hieraus ergibt sich eine zentrale Frage für die Bibliothekswissenschaft: Inwieweit und auf welche Weise können solche Techniken auch für die Bibliografische Kontrolle nutzbar gemacht werden? Im ersten Teil der Arbeit werden die klassischen Konzepte der Bibliografischen Kontrolle analysiert. Als aktuelle Umformungen dieser Komponenten wird auf die Konzeptmodelle des "Bibliografischen Universums" FRBR, FRAD und FRSAD eingegangen. Das Begriffskontinuum Metadaten und Ressourcenbeschreibung wird erläutert und als Bibliografisches System redefiniert, bevor die gegenwärtigen Metadatensystemen abschliessend kritisch betrachtet werden. Im zweiten Teil werden Prinzipien und Technologien beschrieben, die unter dem Begriff Semantic Web zusammengefasst werden und die Struktur des WWW durch maschinenverarbeitbare Informationen erweitern sollen. Ein Überblick über aktuelle Anwendungen in Form von Linked-Data-Projekten schliesst den Teil ab. Im letzten Abschnitt wird erläutert, wie Bibliografische Metadatensysteme durch die vorgestellten Semantic-Web-Techniken reformuliert und integriert werden können. Dies wird danach anhand des DCAM und konkreter Darstellungen von bibliografischen Metadatenschemata, Normdaten und Kontrollierten Vokabularen mittels RDF(S)/SKOS veranschaulicht. Schliesslich wird das neue Katalogisierungsregelwerk Resource Description and Access (RDA) vor diesem Hintergrund betrachtet. Die Arbeit endet mit der Schlussfolgerung, dass Semantic-Web-Techniken dazu geeignet erscheinen, die strukturelle und inhaltliche Komplexität von bibliografischen Metadaten einheitlich darzustellen sowie diese hochgradig anpassungsfähig und universell verarbeitbar zu gestalten. Im Gegenzug können qualitativ hochwertige bibliothekarische Daten als wichtige Referenzpunkte in der sich rasch entwickelnden Linked Data Cloud fungieren - und ihrerseits in ungeahntem Ausmass verknüpft und somit angereichert werden

Resource discovery in heterogeneous digital content environments

The concept of 'resource discovery' is central to our understanding of how users explore, navigate, locate and retrieve information resources. This submission for a PhD by Published Works examines a series of 11 related works which explore topics pertaining to resource discovery, each demonstrating heterogeneity in their digital discovery context. The assembled works are prefaced by nine chapters which seek to review and critically analyse the contribution of each work, as well as provide contextualization within the wider body of research literature. A series of conceptual sub-themes is used to organize and structure the works and the accompanying critical commentary. The thesis first begins by examining issues in distributed discovery contexts by studying collection level metadata (CLM), its application in 'information landscaping' techniques, and its relationship to the efficacy of federated item-level search tools. This research narrative continues but expands in the later works and commentary to consider the application of Knowledge Organization Systems (KOS), particularly within Semantic Web and machine interface contexts, with investigations of semantically aware terminology services in distributed discovery. The necessary modelling of data structures to support resource discovery - and its associated functionalities within digital libraries and repositories - is then considered within the novel context of technology-supported curriculum design repositories, where questions of human-computer interaction (HCI) are also examined. The final works studied as part of the thesis are those which investigate and evaluate the efficacy of open repositories in exposing knowledge commons to resource discovery via web search agents. Through the analysis of the collected works it is possible to identify a unifying theory of resource discovery, with the proposed concept of (meta)data alignment described and presented with a visual model. This analysis assists in the identification of a number of research topics worthy of further research; but it also highlights an incremental transition by the present author, from using research to inform the development of technologies designed to support or facilitate resource discovery, particularly at a 'meta' level, to the application of specific technologies to address resource discovery issues in a local context. Despite this variation the research narrative has remained focussed on topics surrounding resource discovery in heterogeneous digital content environments and is noted as having generated a coherent body of work. Separate chapters are used to consider the methodological approaches adopted in each work and the contribution made to research knowledge and professional practice.The concept of 'resource discovery' is central to our understanding of how users explore, navigate, locate and retrieve information resources.

Prospettive di sviluppo dei cataloghi elettronici

La ricerca offre una riflessione sulla natura e sull’evoluzione dei cataloghi elettronici alla luce delle più recenti innovazioni tecnologiche rappresentate dalla tecnologia dei linked data. Muovendo da un’analisi critica del modello funzionale proposto dagli ‘OPAC di nuova generazione’ e dai ‘sistemi per la scoperta’ si propone la necessità di una revisione del paradigma attuale di sviluppo verso nuovi modelli in grado di sostenere l’apprendimento durante il processo di ricerca dell’informazione. Le più note teorie cognitive dell’information behaviour costituiscono l’orizzonte teorico nel quale viene proposto un nuovo modello per lo sviluppo dell’OPAC fondato sulla centralità dell’utente, sui bisogni informativi, i comportamenti e sull'analisi delle componenti che entrano in gioco nel processo di ricerca. Si esplora, infine, la possibilità che i linked data possano essere la tecnologia più appropriata per la costruzione di nuovi OPAC basati sulla produzione di conoscenza durante il processo informativo
