Figure 4 – Socialization procedures

A user can be a human or a machine. When a user assigns a task to a machine, the machine analyses
the task. Through an analysis of the task, the machine obtains information about the capabilities
needed to achieve the task. If capabilities that are needed are not supported by the machine, the
machine starts to retrieve machines to provide those capabilities. Once the machine finds another
machine to provide the capability, the machine tries to establish a relation with that machine and
achieve the task through that relation. After achieving the task, the relation is released and
socialization is also released.

7 Requirements for machine socialization
This clause describes requirements for machine socialization from an application point of view;
therefore, communication specific requirements are not covered.

7.1 Standardized description of a machine

In a machine socialization, a machine has to find other machines from the perspective of their
capability with which to be associated by a relation. To do this, the machine is required to present
its machine capability(s) in a standardized way. Machine presentation is used to perform service
discovery.

7.2 Service discovery

For a machine to find other machines with the necessary capabilities, service discovery is required.
Through service discovery, a machine can find other machines to be associated with.

7.3 Standardized expression of relation
It is required to express relation information in a standardized form, for example as an extensible
markup language (XML) schema. Relation information encompasses the machines involved, their
association information with other machines and task information which is given to the machines,
etc.
