Aggregation:ArchiMate is a connector. It indicates that an element groups a number of other concepts.
The aggregation relationship has been inspired by the aggregation relationship in UML class diagrams. In contrast to the composition relationship, an object can be part of more than one aggregation.
An aggregation relationship is always allowed between two instances of the same element type.
In addition to this, the metamodel explicitly defines other source and target elements that may be connected by an aggregation relationship.
