## Definitions

### `fyi.opensocial.revision`

**Type**: `record`

A later version of something its author wrote in one of a group's spaces — a thread, a reply — kept beside it rather than written over it, so what points at the original (a reply, a vote) still does. Only the original's author's revisions count; the latest is what's shown, the rest are its history. In the author's own repo, in the same space.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `createdAt` | `string` (datetime) | Yes |  |
| `embed` | `union` | No | Its pictures now; without, it has none. |
| `subject` | `ref` → `com.atproto.repo.strongRef` | Yes | The original, as it was first written. |
| `text` | `string` | No | What it says now: a thread's body, or a reply's text. |
| `title` | `string` | No |  |
