The Visual Restriction Editor is a simple tool that can make it easier to define restrictions that should apply to Properties of a Class.
To use the Restriction Editor, Click on the Restriction Editor tab that appears at the bottom of the SWeDE RDF-XML Source Editor window.
This will initialize and activate the Restriction Editor. After the initialization is complete, you will see a table listing each of the Classes for which there are restrictions in the current document.
The Restriction Editor can help make many common restriction-related tasks easier.
