# What information is included in the DIVOC certificate?
DIVOC’s W3C-based digital certificate consists of three core components:
1. Credential metadata (schema version credential/certificate ID, etc).
2. Claim (vaccination event details).
3. Proof (issuer details, date of issue, time stamp, signature, etc).
### Data structure
The DIVOC digital certificate QR code includes the following data structure:
| Basic components | Information sections | Description |
| ------------------------------------------------------ | ---------------------------- | ------------------------------------------------------------------------------------------------------------------------------ |
| - Credential metadata
| Certificate context | Sets the context, which establishes the special terms. |
| | Certificate identifier | Specifies the identifier for the credential. |
| | Credential type | Declares what data to expect in the credential. |
| | | |
| 2. **Claim** | Credential subject | Assertion about the subjects of the credentials. |
| | Event block | When the credential was issued. |
| | Issuer details | The entity that issued the credential. |
| | | |
| 3. **Proof** | Signature type | Digital proof that makes the credential tamper-evident. Cryptographic signature suite that was used to generate the signature. |
| | Date of signature | When the signature was created. |
| | Digital signature value | |
| | Identifier of the public key | That can verify the signature. |
