# ITMO schema reference

> Canonical reference for ITMO credential structure, required fields, and validation rules.

This page is the canonical **reference** for ITMO credential structure in the Emerging section.\
Use this page for field definitions and validation expectations. For implementation steps in the **Emerging Household Energy** solution, use `/platforms/Emerging/itmo-credentials`.

## Scope

The schema reference covers:

* credential structure and context requirements
* credential subject sections
* validation requirements and proof checks

## Base credential shape

```json theme={null}
{
  "@context": [
    "https://www.w3.org/2018/credentials/v1",
    "https://w3id.org/security/suites/ed25519-2018/v1",
    {
      "itmo": "https://w3id.org/article6/itmo-context.jsonld",
      "prov": "http://www.w3.org/ns/prov#"
    }
  ],
  "type": ["VerifiableCredential", "ITMOCredential"],
  "issuer": "did:example:issuer",
  "issuanceDate": "2024-03-15T00:00:00Z",
  "credentialSubject": {}
}
```

## Credential subject sections

`credentialSubject` should include the ITMO sections used by your implementation:

* `authorizationInfo`
* `ndcQuantification`
* `correspondingAdjustments`
* `environmentalIntegrity`

## Validation checks

Technical checks:

* JSON-LD context resolution and consistency
* schema conformance for required fields
* cryptographic proof verification
* credential status validation

Business checks:

* required ITMO sections are present
* participating parties and references are valid
* adjustment and integrity values are internally consistent
