The Open Data Maturity assessment 2021 benchmarks the development of European countries in the
field of open data.This report aims to support countries to better understand
their level of maturity, to capture their progress over time, to find areas for improvement, and
benchmark this against other countries. Additionally, the study provides an overview of best practices
implemented across Europe that could be transferred to other national and local contexts. The
assessment measures maturity against four open data dimensions:
1) Policy: focusing on countries’ open data policies and strategies
2) Impact: looking into the activities to monitor and measure open data re-use
3) Portal: assessing portal functions and features that enable users to access open data via the
national portal and support interaction within the open data community
4) Quality: focusing on mechanisms that ensure the quality of the (meta)data
