Katalogen som tolkningsredskap : Bibliografiska relationer i Resource Description and Access (RDA), med särskild hänsyn till operationaliseringsproblem / The Catalog as Interpretative Tool : Bibliographic Relationships in Resource Description and Access (RDA), with Special Regard to Problems of Operationalization

Wallheim, Henrik January 2013 (has links)
The new cataloging code Resource Description and Access (RDA) provides a system of instructions for recording relationships between related resources by means of a controlled vocabulary of relationship designators. The purpose of this two years master’s thesis in Archive, Library and Museum studies is to examine the construction of this system, as well as its theoretical foundation. One theoretical point of departure is the necessity of operational definitions for consistent identification of bibliographic relationships. Another such point of departure is that the theoretical model on which RDA is based (the FRBR model) is not a complete description of the biblio­graphic universe, but merely a limited representation of a set of assumptions about that universe. The thesis first examines Barbara B. Tillett's and Richard P. Smiraglia's theories and taxonomies of bibliographic relationships. The analysis shows that, in spite of their claims to provide a theoretical basis for consistent treatment of bibliographic relationships, neither Tillett nor Smiraglia offers operationally applicable definitions. The thesis then turns to RDA in order to examine the instructions and the list of relationship designators. After an introductory survey of RDA chapters 24 to 28, the possibility to record relationship designators at different entity levels is discussed. Remarkably, RDA neither provides instructions for how to choose between the entity levels, nor does it point out what this choice signifies. Finally, a selection of relationship designators representing content relationships is examined. The selected designators are analysed and compared to corresponding categories in literary theorist Gérard Genette's attempt to classify intertextual relationships. The analysis shows that though some of the selected designators are satisfactorily operationalized, most are not.

A Web Semântica pode ser utilizada atualmente apenas em domínios restritos, como em sites de comércio eletrônico, devido à dificuldade de representar ontologicamente toda a Web. Objetiva-se verificar como os conceitos, tecnologias, arquiteturas de metadados utilizados pela Web Semântica podem contribuir à construção, modelagem e arquitetura de metadados de catálogos bibliográficos, tomando por base os conceitos definidos no modelo conceitual desenvolvido para a representação do universo bibliográfico denominado Functional Requirements for Bibliographic Records (FRBR), além de explanar sobre a utilização do modelo conceitual como recurso ontológico. A proposta se pauta no estudo de arquiteturas de metadados semânticas, de modo a identificar suas características, funções e estruturas, além de estudar o modelo BIBFRAME (Bibliographic Framework), que se configura como a iniciativa mais recente acerca da implementação de tecnologias da Web à área da Biblioteconomia e Ciência da Informação. Esta pesquisa caracteriza-se por seu caráter teórico-exploratório e foi desenvolvida mediante análise e revisão de literatura sobre seus temas. Os resultados apresentam as principais arquiteturas de metadados utilizadas no contexto da Web Semântica e uma abordagem sobre ontologias, interoperabilidade em sistemas de informação, modelagem de catálogos online, além da apresentação do modelo BIBFRAME, com base em sua importância para a catalogação. / The proposal of a Semantic Web has emerged as an alternative that would allow the interpretation of information by machines, allowing higher quality in the searches and more relevant results to users. Currently, the Semantic Web can only be used in restricted domains, such as e-commerce sites, due to the difficulty of representing the entire Web ontologically. The objective is to see how the concepts, technologies, architectures, and metadata used by the Semantic Web can contribute to build, model and metadata architecture of bibliographic catalogs, based on the concepts defined in the conceptual model developed for the representation of the bibliographic universe called Functional Requirements for Bibliographic Records (FRBR), and explain about the use of the conceptual model and ontological resource. The proposal is guided in the study of semantic metadata architectures, in order to identify its characteristics, functions and structures, in addition to study the model BIBFRAME (Bibliographic Framework), which constitutes the most recent initiative on implementing Web technologies to the Library and Information Science field. This research is characterized by its theoretical and exploratory character was developed through analysis and review of literature on their subjects. The results show the main architectures used in the metadata context of the Semantic Web and an approach to ontology, interoperability in information systems, modeling catalogs online, besides the presentation of the model BIBFRAME, based on their importance to the Cataloging.
