The Measurement Guide helps governments, civil society, and researchers to understand how to assess open data activities based on the Open Data Charter (the 'Charter') principles. It seeks to shed light on the often opaque and jargon-filled world of open data measurement.The Measurement Guide is an analysis of the Charter principles and how they are assessed based on current open government data measurement tools - with a focus on commitments that can be measured, commitments that cannot be measured, and existing gaps (e.g. commitments that have not been measured).The Measurement Guide is made for governments, civil society, and researchers to under- stand how the Charter principles can be measured. It provides insights from open data experts and members of organizations who work on open data measurement tools. Analysis of the coverage of the five leading open data measurement tools reveals that only parts of Charter principle commitments, and their components, are being measured; or that some commitments could be measured in the future. However, some Charter concepts are either too broad (e.g. “high-quality data”, “usability by the widest range of users”), or lack a shared interpretation, which makes them difficult to find a common indicator.
