The European Data Portal: Scalable harvesting and management of Linked Open Data

Abstract

The European Data Portal fosters the adoption and distribution of Linked Open Data by offering more than 130 million RDF triples. It applies DCAT-AP, the RDF vocabulary for public sector datasets in Europe. Many Open Data solutions do not satisfactorily support this metadata specification. To address this problem, we designed and implemented a novel platform for harvesting and managing native DCAT-AP-compliant RDF. Our approach uses a triplestore as main database and applies state-of-the-art development and deployment patterns to ensure performance and scalability
