# 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. &#x20;

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://open-data-charter.gitbook.io/odcmeasurement-guide/untitled-1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
