# Vocabulary

Set of agreed upon set of words describing data, together with the corresponding definition of each word.

{% hint style="danger" %}
**Disambiguation**

A vocabulary is often referred to as a dictionary. However, "dictionary" has further meaning in the sense that it could be interpreted as a reference for all terms (rather than a specific set), or interpreted as a key-value store by programmers. So we encourage the use of "vocabulary" for this purpose.
{% endhint %}

\*\*Note\*\*

By organizing a vocabulary as a \[taxonomy]\[taxonomy.md], we can see how different entries are related to one another and how they fit into the overall structure of the vocabulary. This can make it easier to learn and use the vocabulary, and can also help understand the meanings of the entries and how they are used in different contexts. %}

## 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://iea-task-43.gitbook.io/iea-task-43-glossary/terms/vocabulary.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.
