## Definition

A ViewpointRole designates the function an InstanceVariable performs in the context of the Viewpoint. (IdentifierRole, AttributeRole, or MeasureRole of interest). Each of three roles within a Viewpoint may be a collection. This happens when a role is mapped to multiple instance variables. In this event a role forms a SimpleCollection. There are SimpleCollections of instance variables in each role.
