ArchiMate Metamodel
Active structure elements are the subjects that can perform behavior.
These can be subdivided into :
- internal active structure elements; i.e., the business actors, application components, nodes, etc., that realize this behavior,
- and external active structure elements; i.e., the interfaces that expose this behavior to the environment.
An interface provides an external view on the service provider and hides its internal structure.
