<Info>
  Protocol definitions specify the complete data model and access rules for structured interactions.

## Protocol Structure

### Definition Components
```json
{
  "types": {
    "post": {
      "schema": "https://schema.org/BlogPosting",
      "dataFormats": ["application/json"]
    },
    "comment": {
      "schema": "https://schema.org/Comment",
      "dataFormats": ["application/json"]
    }
  },
  "structure": {
    "post": {
      "comment": {}
    }
  },
  "permissions": {
    "post": ["author", "admin"],
    "comment": ["anyone"]
  }
}
```

### Key Elements
- **Types**: Record type definitions with schemas
- **Structure**: Hierarchical relationships
- **Permissions**: Access control rules
- **Actions**: Allowed operations per type

## Protocol Analysis

<Tip>
  Examine existing protocols to understand best practices before creating your own.
</Tip>

### Understanding a Protocol
1. **Review Types**: What data can be stored?
2. **Check Structure**: How is data organized?
3. **Verify Permissions**: Who can access what?
4. **Test Compatibility**: Does it meet your needs?

## Common Protocol Patterns

### Social Media Protocol
- Posts, comments, reactions hierarchy
- Public read, authenticated write
- Media attachment support

### Healthcare Protocol
- Patient records, visits, prescriptions
- Strict access control
- Mandatory encryption

### IoT Protocol
- Device registry, telemetry, commands
- Time-series data structure
- Rate-limited writes

<Warning>
  Protocol URIs must be URL-encoded when used as path parameters.
</Warning>

## Integration Example

```bash
# Get protocol definition
PROTOCOL_URI="https://protocols.sonr.io/social/v1"
snrd query dwn protocol did:sonr:alice "$PROTOCOL_URI"

# Parse and adopt
snrd tx dwn protocols-configure --copy-from did:sonr:alice --protocol "$PROTOCOL_URI"
```
