Report on Data Homogenisation for High-value Datasets

This report focuses on the European Union’s open data policies, more specifically on Directive 2019/1024 (EU), also known as the open data directive, which defines the concept of high-value datasets (HVDs). An Implementing regulation that must be implemented by June 2024 lays down a list of specific high-value datasets in each of the six main categories identified in the directive: geospatial, Earth observation and environment, meteorological, statistics, company and company ownership, and mobility.
This study, proposes a methodological approach that facilitates the identification and homogenisation of HVDs, using selected examples of HVDs from three distinct categories. The insights of this report provide a roadmap for homogenising datasets across European countries and enhancing interoperability.
