Daniel Vila - A Library Linked Data use case: datos.bne.es and MARiMbA

In this talk I will first present the current status of what has been called Library Linked Data, or in other words how libraries and other cultural heritage institutions are shifting towards openness and the Web, by publishing their data following the Linked Data principles using RDF, URIs, RDF(S), etc. In the same line, I will briefly present the findings and reports published by the W3C Library Linked Data Incubator Group. In the second part of the talk, I will present the datos.bne.es project, an effort by the National Library of Spain together with the Ontology Engineering Group (UPM, Madrid). I will discuss the initial requirements, the methodological approach, and the research questions raised by the process of mapping and transformation of the source data (in MARC21 format) into RDF using RDFS/OWL ontologies . Also, I will talk about MARiMbA the tool developed within the context of the project and that supports the ETL process and its main goal : ensuring the quality of the produced data and coverage of the source data while facilitating the mapping task to the domain experts (librarians). Finally, I will present the results of the project, discuss the future lines and compare datos.bne.es to other projects of big National Libraries in Europe, in terms of the resulting data, the methodological and the technological aspects.
