# How It Works

Although the Participant Registry is not explicitly shown in operational data exchange flows, it plays a critical role as a prerequisite for trusted interactions.

A typical sequence of how it is used can be described as follows:

While the Participant Registry plays an important role within the iSHARE Trust Framework, it typically operates in the background rather than directly interacting with participants. Instead, it provides the trust context that enables interactions to take place, as illustrated in this[ use case](https://ishare.eu/ecosystem/ishare-in-data-spaces/dvu/).&#x20;

Without this layer, participants would need to establish trust manually, significantly reducing scalability and interoperability.

### Importance and Value

The Participant Registry is a foundational component for enabling trusted, scalable, and interoperable data spaces.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://trustbok.ishare.eu/apply-ishare/participant-registry/how-it-works.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.
