Over the last decade, more and more governments have opened up the data that they hold so that it can be used to improve services, spur economic growth and hold officials to account. Several tools have been developed in order to measure how well governments are doing. These tools have a number of objectives including highlighting implementation gaps and providing a way to hold officials to account.

Each tool has a different approach, methodology, and coverage. However, all of the main open data measurement tools are trying to move towards using the Open Data Charter as the starting point for their analysis. This briefing summarises the main open data measurement tools.

The Charter’s network is currently working on a project to better understand which Charter commitments are measurable and which are not. We also want to understand where the measurement gaps are. Get in touch with us if you’re interested in taking part by emailing  

The chart below shows the key features of the four main tools measuring how well national governments are sharing open data. At the moment there are limited tools assessing how well subnational governments (e.g. states, provinces, and cities) are doing at publishing open data.

  • The following tools include an assessment of open data as part of a broader survey at open government:

    • UN E-Government Survey: The study includes questions on open data. It covers all 193 UN countries and is based on a survey completed by governments.
    • Open Government Partnership Independent Review Mechanism (OGP IRM): The OGP IRM is an independent review of the commitments that governments have made as part of their OGP National Action Plans, a number of which include open data activities.

    The following are assessment tools that individual governments or organizations can use to measure their progress:

    • Open Data Readiness Assessment tool (ODRA): Developed by the World Bank, this tool can be used to carry out an assessment of how ready a government or individual agency is to implement an open data initiative.
    • Open Data Certificate: A free online tool developed by the Open Data Institute to assess and recognize the sustainable publication of quality open data. It assesses the legal, practical, technical and social aspects of publishing open data using best practice guidance.
    • Open Data Maturity Model: A framework by the Open Data Institute to assess how well an organization publishes and consumes open data, and identifies actions for improvement.
    • 5 stars of linked open data: Developed by Tim Berners-Lee, this assesses how easy it is to link a specific dataset to other datasets.
    • Periodic Table of Open Data’s Impact Factors: Based on the existing literature and case studies, GovLab developed an approach outlining the enabling conditions and disabling factors that often determine the impact of open data initiatives.
