# Extending OpenAPI { #extending-openapi }

There are some cases where you might need to modify the generated OpenAPI schema.

In this section you will see how.

## The normal process { #the-normal-process }

The normal (default) process, is as follows.

A `FastAPI` application (instance) has an `.openapi()` method that is expected to return the OpenAPI schema.

	// Is compression enabled?
	globalCompressConfigMu sync.Mutex
	globalCompressConfig   compress.Config

	// Some standard object extensions which we strictly dis-allow for compression.
	standardExcludeCompressExtensions = []string{".gz", ".bz2", ".rar", ".zip", ".7z", ".xz", ".mp4", ".mkv", ".mov", ".jpg", ".png", ".gif"}

	// Some standard content-types which we strictly dis-allow for compression.

Previously, there was no formalization of property naming; only loose conventions were followed.
While these conventions served relatively well in practice, they created gaps, resulting in a loss of uniformity in some cases and leaving friction in the process of naming new properties.

### Terminology

**Public properties** are formally a part of the Public API.
