  • Fue una excelente excelente presentación y un gran orgullo ver a la Biblioteca Nacional de España junto a la francesa o la alemana presentar su proyecto en esa linea. Sally McCallum y Barbara Tillet hicieron también impresionantes presentaciones, como era de esperar. Yo mismo también intervine, gracias a la generosidad de Elena, y me puse muy de estar allí, en la presentación del informe final del W3C Library Linked Data Incubator Group. España estaba dónde tenía que estar, lo que no ocurre muy a menudo.

  3. 3. Project background Cooperation project between BNE and national and regional libraries of Spain GOAL: Create a Unified Authority System (similar to VIAF approach) MAIN ISSUE: Multilinguality Various approaches were analysed and tested, but were not succesfulLinked Data at the BNE
  4. 4. Project background Around January 2011 the joint project “Preliminary study of Linked Data” between the BNE and OEG startsLinked Data at the BNE

  6. 6. Data source set: Cervantes and surrounding data MARC data selection involved 3 phases: Phase 1: Authority records: Cervantes + each record that contained Cervantes as author (author-title, author-title-lang, etc.) –> 550 records Bibliographic records: Associated to selected set of authoritities 8552 records Phase 2: Authority records: Records associated to selected set of bibliographic records in Phase 1 7351 records Phase 3: Authority records: Authority records related within any field with selected set in Phase 2. (Mainly themas and works and expressions from authors of phase 2) 53000 recordsLinked Data at the BNE 6

  8. 8. URI Design Followed Cool URIs and Linked Data patterns (Natural keys) A-Box: http://cultura.linkeddata.es/BNE/resource/<Class>/<ID> T-Box: Opaque URIs Multilingual labels (EN, ES, HR..) Available at metadataregistry.org Base URI: http://iflastandards.info/ns/ Not published, will be published soon not dereferenceableLinked Data at the BNE
  9. 9. Process Overview OBJECTIVES: 1. Find a systematic and repeteable transformation methodology 2. Design and implementation of lifecycle supporting tools (mapping, cleaning, transformation, linkage). 3. Proove applicability of IFLA RDF/OWL models Lifecycle Process : Iterative and incremental Joint effort from two different worlds: Libraries and Semantic Web (Linked Data)Linked Data at the BNE 9
  10. 10. Main activities1. Data analysis: Understand records’ organization and structure (Authorities and bibliographic) Development of analytical tools (fields and subfields combination reports, etc.)2. Mapping MARC21 to chosen Models Very complex process ASSET: Tool for mapping templates generation, with analytical data from input records3. Data transformation to RDF: Ad-hoc transformation toolLinked Data at the BNE 10
