1 Scope
This Recommendation specifies machine socialization which enables machines to cooperate with
one another using their relations with other machines. This Recommendation covers the following:
– overview of machine socialization;
– requirements for machine socialization; and
– reference models of machine socialization including a service model and functional model.

3 Definitions

3.1 Terms defined elsewhere
This Recommendation uses the following terms defined elsewhere:

3.1.1 Internet of things (IoT) [ITU-T Y.4000]: A global infrastructure for the information
society, enabling advanced services by interconnecting (physical and virtual) things based on
existing and evolving interoperable information and communication technologies.
NOTE 1 – Through the exploitation of identification, data capture, processing and communication
capabilities, the IoT makes full use of things to offer services to all kinds of applications, whilst ensuring that
security and privacy requirements are fulfilled.

NOTE 2 – From a broader perspective, the IoT can be perceived as a vision with technological and societal
implications.
3.1.2 thing [ITU-T Y.4000]: In the Internet of things, this is an object of the physical world
(physical things) or of the information world (virtual things), which is capable of being identified
and integrated into communication networks.

3.2 Terms defined in this Recommendation

This Recommendation defines the following terms:
3.2.1 machine: An object of the physical world which is capable of being identified and of
communicating, computing and processing data.
3.2.2 machine socialization: Enabling things or machines to communicate what they do or what
they need, as well as to follow one another, discuss with one another and collaborate with one
another.
