# Appendix

### Proof response <a href="#proof-response" id="proof-response"></a>

Explanation of `Proof`attributes:

* `ìd`: This item is a unique identifier of the proof. It summarizes the content of the proof but not the authentication of its issuer. This attribute defines its position in the trust registry.
* `commitment`: This is the hash that guaranties integrity of the whole proof.
* `commitment_details`: These items are the intermediate values used to create and structure the commitment, they are sent to Archipels during the proof creation to validate integrity of the commitment.
* `anchor_id`: This value indicates in which batch the proof will be anchored on the Blockchain.
* `status`: When creating a proof, its status is first `pending`, then it becomes `registered` when the proof is included in the trust-registry and then it becomes `included` when the root of the trusted registry is anchored on the blockchain and fully timestamped and made immutable.
* `metadata`: These metadata are the values used to verify a proof. Each metadatum has a `value` which can be a hash or a standardized value of an input. It also has an inclusion proof that proves cryptographically that this value is included in the `proofId`. And it has a `publication_flag` which specifies how this metadata can be used during proof verification. If this flag is set to `private`then the metadatum is only used by Archipels for consistency checks. If the flag is set to `public` then the metadatum is sent to the verifier when a verification matches this proof. If this flag is set to `searchable` then the metadatum is only used to match with a proof verification.

# Agent Instructions
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://docs-v1.archipels.io/technical-documentation/integration-guide/appendix.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.
