Models, Views and Viewpoints
HOPEX for the ArchiMate Framework supports the viewpoints mechanism defined by the ArchiMate® standard:
• Viewpoints define which concepts (elements or relationships) are useful in a particular type of view,
• Views can be created after a given viewpoint within an ArchiMate® Model.
The diagram views of the diagram describing a view are initialized according to the viewpoint definition; it is then possible for the user to restrict / extend this selection to hide or add necessary additional concepts.
The diagram views are defined based on the generic metamodel and layers (e.g. Business Layer Active Structures activates ‘Business Actor', ‘Business Collaboration', ‘Business Role' and ‘Business Interface' concepts).

The number of diagram views being limited in
HOPEX, the additional layers (motivation, implementation & migration, strategy) diagrams views are more limited so that requiring one concept (e.g. outcome) in one viewpoint will activate the whole view (e.g. motivation), so that additional concepts are also made available (e.g. value, meaning)
