The **Link Entity** has 7 attributes. `id`, `title`, `url`, `slug`, `user_id`, `created_at` and `updated_at`. However some of these attributes rely on gems and other Entities therefore we only need to establish the independent attributes for the time being. Which are `id`, `title`, `url`, `created_at` and `updated_at`.
