A template that defines which objects a model can contain and how these objects relate to other objects. It defines the context in which the derived models are relevant.

In contrast, models derived from the model type Organizational chart are located in the context Organization; they visualize the organizational structure of a company, for example, which organizational units exist, how organizational units are linked hierarchically, who manages the organizational units, and who is assigned to them.
