# Measuring the Open Data Charter principles

This section provides an analysis of the Charter principles and their commitments. The mapping analysis includes an in-depth look at the indicators and methodologies that five leading measurement tools — ODB, GODI, ODIN, OURdata, and EODMA — use to assess open government data, and how they measure, or do not measure Charter principle commitments. We focus on these measurement tools because they are used across a large number of countries to assess national open government data initiatives. It is important to note that this guide is equally useful to assess government open data initiatives on a regional or at a city level.
