A Review of Linked Open Data Projects at the National Library of the Netherlands (KB)

From the National Library of the Netherlands (Koninklijke Bibliotheek) Research in KB Blog:

While the work on linking our metadata continues, the library’s Research department is currently involved in an effort to link named entities in our full text collections. The purpose of this project is to contribute to a fully Linked Open Data-enabled library, entailing an enhanced user experience and improved discovery based on semantic relations. To further contribute to the progress of the semantic web, we will offer our full text enrichments as open data.


The Research department created an enrichment database to collect information about the named entities and to store links to external resources. We are currently linking the named entities to DBpedia, while simultaneously storing links to related resource descriptions in Freebase and VIAF. This will be further extended to other resources, such as genealogy databases. Additionally, we will develop software for ‘socially enhanced linking’, i.e. tools allowing users to validate or reject links that were obtained automatically and to create new links for resources.


The National library’s Senior researcher Theo van Veen sees the future of Linked Open Data as “a single worldwide resource description database which will replace most or all bibliographic thesauri, with all resources mentioned in metadata or text linking to the same single identifier”.
