perspectives cut across the views. In other words, they do not replace views but
provide an abstraction layer above the views. In this document we cover the
following architectural perspectives:

 Evolution and interoperability;

 Performance and scalability;

 Trust, security, and privacy;

 Availability and resilience.

Of the above perspectives only one is covered at the level of the IoT Reference
Model: Trust, Security and Privacy.

The table below summarises how the models in the IoT Reference Model relate
to the views and perspectives featured in the IoT Reference Architecture.
