Single properties - Files

A string property can be rendered as a file upload form if it has the contentMediaType attribute or the x-display=file annotation.

An object property can also be rendered as a file upload. In this case the name, type, size and lastModified subproperties will be filled with metadatas from the uploaded file. By default the data subproperty will contain a reference to a File/Blob object, except if you define its type as string.
