Fabian Kirstein, Benjamin Dittwald, Simon Dutkowski, Yury Glikman, Sonja Schimmler, Manfred Hauswirth
2019 Lecture Notes in Computer Science  
The platform is a starting point in adopting the Linked Data specification DCAT-AP, aiming to increase interoperability and accessibility of Open Data.  ...  The European Data Portal (EDP) is a central access point for metadata of Open Data published by public authorities in Europe and acquires data from more than 70 national data providers.  ...  We would also like to thank the entire consortium of the European Data Portal for making this work possible.  ...

Open Data and the Status Quo – A Fine-Grained Evaluation Framework for Open Data Quality and an Analysis of Open Data portals in Germany [article]

Lisa Wenige, Claus Stadler, Michael Martin, Richard Figura, Robert Sauter, Christopher W. Frank
2021 arXiv   pre-print
This paper presents a framework for assessing data and metadata quality within Open Data portals.  ...  To address this research gap, we have designed a quality framework that is able to evaluate data quality in Open Data portals on dedicated and fine-grained dimensions, such as interoperability, findability  ...  This has been validated by the analysis of the German Open Data landscape. The approach can be transferred to other platforms and landscapes for a comprehensive benchmarking of Open Data quality.  ...
