Umbraco Property Editor Schema

Handles the server-side schema half of Umbraco property editors, defining how data gets validated and stored. The skill steers you toward built-in schemas like Umbraco.Plain.String or Umbraco.Plain.Json when possible, which covers most cases. It only generates custom C# schema classes when you need specialized validation or custom value converters for rendering. Pulls fresh docs from the official Umbraco site before implementation and includes a helpful reference table of built-in schema aliases. The honest take: most developers building custom property editors can skip the schema entirely and just reference a built-in one in their UI manifest, but this makes the custom path straightforward when you actually need it.

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.
