# Overview

> An entry represents a single index or code number inside a series. Essentially, it's a mapping of a UUID to a code number.

## Models

An `Entry` contains the following fields:

| Property      | Type                 | Description                                         |
| ------------- | -------------------- | --------------------------------------------------- |
| `id`          | uuid                 | UUIDv1 value that uniquely identifies the entry.    |
| `series_id`   | uuid                 | ID of the series this entry belongs to.             |
| `code`        | string               | The code generated for this entry.                  |
| `meta`        | map\<string, string> | Any additional meta data provided during creation.  |
| `previous_id` | uuid                 | ID of the last entry created in the series, if any. |
