public interface RelationBase extends SpecializableTerm
A representation of the model object 'Relation Base'. RelationBase is a specializable term that is the abstract superclass of a relation from a source [=entity=] to a target [=entity=]. It can optionally name a [=ReverseRelation=] whose domain is the target and whose range is the source. Such relation can only be specified on a relation base definition not a ref to an existing one. A relation base can be characterized with several boolean flags that represent its DL semantics. Such flags apply conversely to the [=ReverseRelation=] (if named).

The following features are supported:
