After choosing a relation, if the relation allows a closure, the closure check box will be available. Checking this box applies the relation repeatedly.
For example, a closure on the relation "has type" will return not only all subclasses, but all subclasses of those subclasses, and so on.
If an attributed relation is chosen, there will be additional options to define restrictions on the relation's attributes and values.
The current list of relations allowing closures and attributed relations is predefined. Please contact the people currently maintaining EmilyLite to add or redefine relations.
