The object of study is framed by an understanding of analogic bibliographic record conversion to the Bibliograhpic MARC21 format, based on a syntactic and semantic analysis of records described according to descriptive metadata structure standards and content standards. The thesis in this research is that the syntactic and semantic principles of bibliographic records, defined by description and visualization cataloguing schemes, present in the descriptive metadata structure standards and content standards, determine the bibliographic record conversion process to the MARC21 Bibliographic Format. In the light of this, the purpose of this research is to develop a theoretical study of the syntax and semantics of bibliographic records, grounded in Linguistic theories of Saussure and Hjelmslev, which can underlie analogic bibliographic record conversion to the MARC21 Bibliographic Format using a computational interpreter. To this end, the general aim was to develop a theoretical-conceptual model of the syntax and semantics of bibliographic records, based on saussurean and hjelmslevian linguistic studies of human language manifestations, which can be applicable to a computational interpreter designed for the conversion of bibliographic records to the MARC21 Bibliographic Format. To attain this goal, the following specific objectives were identified, in two groups and related to the theoretical-conceptual model of bibliographic record syntax and semantics and to the conversion process of the records, respectively: to make explicit the relationship between the syntax and semantics of bibliographic records...

Apesar da importância desses e de outros padrões de metadados internacionalmente aceitos, existem sistemas de gerenciamento de bibliotecas que utilizam padrões de metadados próprios, o que reduz as possibilidades de intercâmbio de registros e pode ocasionar conflitos durante a migração entre sistemas. Diante dos sistemas de gerenciamento de bibliotecas que não utilizam qualquer padrão de metadados internacionalmente aceito, tem-se como problema a conversão dos registros desses sistemas em registros nos Formatos MARC 21. Para que possam ser processados, os registros nos Formatos MARC 21 devem estar codificados de forma que seu conteúdo possa ser identificado por aplicações de informática. As tecnologias para essa codificação têm evoluído da tradicional norma ISO 2709 até a Extensible Markup Language (XML). A codificação com a XML trouxe a possibilidade de converter os registros utilizando folhas de estilo de transformação elaboradas com a linguagem Extensible Stylesheet Language for Transformation (XSLT). Considerando a necessidade de converter registros para os Formatos MARC 21 e as possibilidades trazidas pela XML, o objetivo geral desta pesquisa é elaborar um modelo para a conversão de registros de distintos padrões de metadados codificados com a XML em registros nos Formatos MARC 21, tendo como um dos pontos centrais desse modelo a utilização de folhas de estilo de transformação elaboradas com a XSLT. Para esse objetivo, é realizada uma revisão de literatura sobre a conversão de registros, os Formatos MARC 21, a ISO 2709, a XML, a XSLT e o MARCXML. São destacados os principais aspectos da utilização da XML na codificação de documentos e as possibilidades oferecidas pela XSLT. Para discutir a relação entre os Formatos MARC 21 e a XML é apresentada a linguagem de marcação MARCXML. A partir do estudo teórico, é elaborado um modelo para a conversão de registros. São descritas as etapas e os componentes do modelo, assim como sua validação por meio da aplicação na conversão de registros bibliográficos exportados pelo sistema de gerenciamento de bibliotecas Personal Home Library (PHL). Como considerações finais, são destacadas as características do modelo e são sumarizadas algumas questões sobre sua utilização e sobre os instrumentos resultantes de sua aplicação na conversão de registros do PHL. / MARC 21 Formats are metadata standards internationally used for records interchange in bibliographic domain. Despite the importance of the MARC 21 Formats and other international metadata standards, there are integrated library systems that use their own metadata standard. The non-use of international metadata standards decreases the possibilities of records interchange and it might cause problems during data migration between systems. In face to the integrated library systems that do not use international metadata standards, our research question is the conversion of the records from these systems to MARC 21 records. In order to be read, MARC 21 records must be coded in such a way that allows informatics applications to recognize the record content. The technologies used for this codification have evolved from traditional ISO 2709 standard to Extensible Markup Language (XML). The use of XML in the codification gave us the possibility to use transformation stylesheets created with Extensible Stylesheet Language for Transformation (XSLT) for the records conversion. Considering the need of records conversion and the possibilities brought by XML, we aim to develop a model for conversion of records that were created with different metadata standards and are coded in XML to MARC 21 records using XSLT stylesheets. For this purpose, we made a literature review about record conversion, MARC 21 Formats, ISO 2709, XML, XSLT and MARCXML. We highlighted the main issues on the use of the XML for documents codification and the possibilities provided by XSLT. In order to discuss the relation between MARC 21 and XML, we presented MARCXML markup language. Starting from the literature review, we developed a model for record conversion and described its components and its steps, as well as its validation through the use in the conversion of bibliographic records from Personal Home Library (PHL) integrated library systems. In conclusion, we highlighted the characteristics of the model and we summarized some issues related to the use of the model and to the instruments that came from the application of the model in the PHL records conversion.
