processing run time environment) as required by IoT data provider, IoT data carrier, IoT data
application provider and IoT data consumer for the support of data operations execution.
– IoT data consumer: The IoT data consumer consumes IoT data. Usage of the consumed data
depends on the application purposes.
– IoT data carrier: The IoT data carrier carries data among the IoT data provider, the IoT data
framework provider, the IoT data application provider and the IoT data consumer.
NOTE 2 – An actor of a concrete IoT deployment can play multiple roles. As an example, an actor
executing data analysis plays the role of IoT data application provider, but it also plays the role of
IoT data provider when it sends the results of this data analysis to other actors.

Figure 2 shows key possible mappings from IoT business roles [ITU-T Y.4000] to the above described IoT data
roles.

Figure 2 – Key possible mappings from IoT business roles to IoT data roles

NOTE 3 – Figure 2 is an abstract representation of multiple possible IoT deployments. In fact, as shown in
Figure 2, from an IoT data perspective, the same IoT business role may be mapped to multiple IoT data roles.

As an example, concerning the device provider, when it provides its collected data to other IoT business roles
(including platform provider, application provider and application customer), it acts as IoT data provider; on
the other hand, when it consumes IoT data provided by other IoT business roles (including network provider,
platform provider and application provider), it acts as IoT data consumer; finally, when it provides
applications related to IoT data processing capabilities to other IoT business roles (including network
provider, platform provider and application provider), it acts as IoT data application provider.

An example of deployment scenarios with respect to IoT data roles is described in Appendix II.1.

6.3 Challenges of the IoT from the IoT data roles perspective
The IoT is a system that can connect things, capture, aggregate, transfer, store, analyse and query IoT data
and provide things-related services. The IoT faces the challenges of IoT data from the perspective of the
various roles related to IoT data as described in clause 6.2.
