Umbraco Property Editor Schema

What is it?

A Property Editor Schema defines the server-side metadata and configuration structure for a property editor - essentially the "blueprint" for how data is stored and processed. It's one half of a property editor (paired with a Property Editor UI). The schema determines data validation, storage format, and how property data is made available when rendering the website. Most custom editors can use built-in schemas; custom schemas are needed for specialized data handling.

Documentation

• Extension Registry: https://docs.umbraco.com/umbraco-cms/customizing/extending-overview/extension-registry

When to Create a Custom Schema

Use a built-in schema when possible. Create a custom schema when you need:

• Custom server-side validation
• Special data transformation before storage
• Custom property value converters for rendering
