Item definition overview
A Microsoft Fabric item definition is an object that represents the structure and format from which an item is built. A Fabric item definition includes the mandatory system files that define the item's characteristics. Each item type in Fabric has different supported formats and required files (parts) that make up its definition.
Definition based APIs
Definition based APIs return a definition within the response or support providing the definition in the payload.

- Get Item Definition - Always returns the platform file.
