:::info
|
|
Records are the fundamental unit of data storage in DWN, supporting any data type with optional encryption.
|
|
:::
|
|
|
|
## Key Features
|
|
|
|
### Data Organization
|
|
- **Hierarchical Structure**: Use `parentId` to create nested record relationships
|
|
- **Protocol Compliance**: Conform to defined data structures via `protocol` and `protocolPath`
|
|
- **Schema Validation**: Enforce data integrity with JSON Schema URIs
|
|
|
|
### Privacy & Security
|
|
- **Encryption**: Client-side encryption before storage
|
|
- **Published Flag**: Control public accessibility
|
|
- **Attestations**: Cryptographic proofs of data integrity
|
|
|
|
### Common Use Cases
|
|
- **Personal Documents**: Store encrypted files and documents
|
|
- **Application Data**: Persist app-specific user data
|
|
- **Social Content**: Share public posts or media
|
|
- **Health Records**: Store sensitive medical data with encryption
|
|
|
|
:::tip
|
|
Use protocol definitions to ensure data interoperability across applications.

## Example Record Types
|
|
|
|
```json
|
|
{
|
|
"protocol": "https://protocols.sonr.io/social/v1",
|
|
"protocolPath": "/posts/2024",
|
|
"schema": "https://schema.org/BlogPosting",
|
|
"published": true,
|
|
"data": "base64_encoded_content"
|
|
}
|
|
```
|
|
|
|
:::warning
|
|
Records exceeding `maxRecordSize` will be rejected. Large files should be stored in IPFS with only metadata on-chain.
