Figure 2 – E-R diagram of socialization

As shown in Figure 2, socialization can be established by establishing a relation or relations. A
relation is an association between or among machines to enable a machine to expose its capabilities
to other machines for collaboration. Once a machine is associated with other machine(s) as a
relation, their capabilities can be exchanged to achieve a given task.
Figure 3 presents an E-R diagram of a relation as an example. In this example, three machines are
associated as a relation. Each machine has different properties and capabilities. This relation
includes machine information of machines that are involved in socialization and also includes
procedures to be carried out in each machine to achieve a given task. This procedure defines
sequential actions for each machine and the relationship between or among capabilities of the
machines.
In a relation, output from one machine can be transferred to another machine as an input. Display
mirroring is an example of this property. Some vehicles can be associated with a smart phone for
mirroring a smart phone's display. In this case, navigation information can be displayed in a vehicle
with the aid of a smart phone, even if the vehicle does not have a navigation system.
