## Definitions

### `app.standard-reader.labeler.service`

**Type**: `record`

Registers a Standard Reader labeler. This record is the single source of truth for a labeler: its identity, where to reach its label server, how it presents, and its label-value definitions. Indexed off the network like any other record (the owner of the record is the labeler's author); the label server itself only answers com.atproto.label.queryLabels / subscribeLabels.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `did` | `string` (did) | Yes | DID of the labeler — the `src` on its labels (and whose key signs them). |
| `avatar` | `blob` | No |  |
| `policies` | `ref` → `app.standard-reader.labeler.defs#labelerPolicies` | No |  |
| `createdAt` | `string` (datetime) | Yes |  |
| `description` | `string` | No |  |
| `displayName` | `string` | No |  |
| `serviceEndpoint` | `string` (uri) | Yes | Origin serving this labeler's com.atproto.label.queryLabels / subscribeLabels. |
