Mit derselben Technik können Sie das JSON-Schema erweitern und Ihre eigenen benutzerdefinierten Zusatzinformationen hinzufügen.

Sie könnten das beispielsweise verwenden, um Metadaten für eine Frontend-Benutzeroberfläche usw. hinzuzufügen.

`Body` also has all the same extra validation and metadata parameters as `Query`,`Path` and others you will see later.

## Embed a single body parameter

Let's say you only have a single `item` body parameter from a Pydantic model `Item`.

## Issue management

We use GitHub to track all of our bugs and feature requests. Each issue we track has a variety of metadata:

- **Epic**. An epic represents a feature area for Istio as a whole. Epics are fairly broad in scope and are basically product-level things.
Each issue is ultimately part of an epic.
