public interface AttributeType
extends PropertyType

The type of an attribute.

An attribute is similar to the notion of a UML attribute, or a field of a java object. See the javadoc of Attribute for more info on the semantics of attributes.

Identifiableness

An attribute may be "identifiable". When this is the case the attribute has a unique identifier associated with it. See Attribute.getIdentifier(). The type of the attribute specifies whether it is identifiable or not (isIdentified().
