# Default keyword schema example

This schema example shows how to use the [default](https://amplience.com/developers/docs/schema-reference/json-schema) keyword to set initial values for items. You can use the `default` keyword with strings, numbers, booleans and lists, as well as content and image links.

## Pre-requisites

None. This is a self contained schema.

## How to use

Use the examples in this schema as a starting point for applying `default` values to your own properties.

> **Info:** To use the `example-image-link` and `example-content-link` properties, you will need to update these properties to use an image and a content item from your own hub.

In the `example-image-link` property, the default value includes all the properties returned by an `image-link` object, including the id, name, endpoint and default host. The easiest way to find all these values is to publish a content item containing the image and view the item in JSON format from a link in the "Content delivery" section of the content form. See [content item properties](https://amplience.com/developers/docs/user-guides/produce-content/create#content-item-properties) for more details.

For the `example-content-link` property you can also find the contentType and id fields from the content item properties window and use these values to define a default `content-link`.
