Figure 1 : IoT Architectural Reference Model building blocks.To organisations, an important aspect is the compliance of their technologies with
standards and best practices, so that interoperability across organisations is
ensured. If such compliance is given, an ecosystem may form, in which every
stakeholder can create new businesses that ―interoperate‖ with already existing
businesses. The IoT ARM provides best practices to the organisations so that they
can create compliant IoT architectures in different application domains. Those IoT
architectures are instances from the Reference Architectures with some architectural
choices (called later on Design Choices) like considering strong Real/Time or
choosing strong security features, etc. They consist of special ―flavours‖ of an IoT
Reference Architecture where of course interoperability is not sacrificed but on the
contrary ensured.
When application domains are overlapping, the compliance to the IoT Reference
Architecture ensures the interoperability of solutions and allows the formation of new
synergies across those domains.
The rest of this chapter organises as follows. In Section 1.1 we give some
information about the technical improvements brought to the former version (v2) of
the ARM, namely D1.4 (mainly useful to D1.4 readers). Then in Section 1.2 we
outline the structure of the document. Section 1.3 gives some hints about the various
project input documents used for writing this deliverable. Finally Section 1.4
summarises in a table, which aspects of other IoT-A technical work packages relate
to the D1.5 document, and where relevant information can be found in this
document.
1.1 What is new in D1.5?
D1.5 is the fourth and final public version of the Architectural Reference Model. It
leverages on D1.4 and an intermediary internal report IR1.5 released internally
earlier this year. D1.5 is the third full version of the ARM and will also be called ARM
v3.
