## Definitions

### `app.certified.feed.like`

**Type**: `record`

Record declaring a 'like' of a piece of subject content. Social feedback only: a like carries no protocol meaning about the subject (it is not an evaluation, endorsement, or acknowledgement). Schema-compatible with app.bsky.feed.like.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `createdAt` | `string` (datetime) | Yes | Client-declared timestamp when this record was originally created. |
| `signatures` | `ref` → `app.certified.signature.defs#list` | No | Optional cryptographic signatures attesting to this record's content. |
| `subject` | `ref` → `com.atproto.repo.strongRef` | Yes | Strong reference to the record being liked. May be a record of any lexicon (e.g. an activity, a collection, or a repost's subject). |
| `via` | `ref` → `com.atproto.repo.strongRef` | No | Optional strong reference to the record through which the subject was encountered, typically an app.certified.feed.repost. Lets AppViews credit the account that surfaced the subject. Mirrors the optional `via` field on app.bsky.feed.like; the referenced record may conform with any lexicon. |
