Transformation of a Library Catalogue into RDA Linked Open Data
The 200,000 records in the catalogue of the Biblioteca Virtual Miguel de Cervantes have been migrated to a new relational database whose data model adheres to the FRBR and FRAD specifications. The database content has been later mapped to RDF triples which employ the RDA vocabulary to describe the entities, as well as their properties and relationships. The intermediate relational model —ensuring, for example, referential integrity— provides tighter control over the process and, therefore, enhanced validation of the output. This RDF-based semantic description of the catalogue is now accessible online and supports browsing and searching the information.
