# Events

## Overview

As part of the **Functional Architecture**, the **Events** section describes the events module in OpenCRVS — how different civil event types are modelled and configured.

It is organised into the following modules:

* **Types** — describes how event types (for example, birth, death, marriage) are defined and linked to forms, statuses, actions, and outputs.
* **Business Rules** — shows how legislation and policy are translated into configurable rules that control which actions are available, when declarations become late, when approvals are required, and related behaviour.
* **Forms** — explains how event forms are configured to capture Notify/Declare, Correct, and other action data, including pages, fields, validations, and evidence uploads.
* **UINs** — describes how unique identifiers (for example, Tracking ID, Registration number, National ID integration) are generated or captured for events and how they are used across workflows and search.

Together, these modules show how to configure each event type so that it reflects national law and policy while using a consistent model across OpenCRVS.
