Because of its hierarchical structure, the 1dok meta data model makes it possible for its users to optimate communication tracks within given communicative situations. On the model of a public administration to come, the illustration (see below) shows an optimal network of the separate offices. In in the field of residents´ registration affairs, "office 2" may communicate with "office 3" via "technical terms residents "registration affairs". On the right side, the "technical terms financial affairs" will be used in the same way. If two offices from different fields want to communicate, they will look for the "smallest common denominator". In the example, it is represented by the "public administration" with the related "technical terms common administration (DOMEA)".
