example

Deploy process
models to
execution
environments

Activities of IoT-aware process models are

applied to appropriate execution environments,

which perform the actual process execution by

finding and invoking appropriate IoT Services.

C.1.2.1

Align application
requirements with
service capabilities

For the execution of applications, IoT Service

requirements must be resolved before specific

services can be invoked. For this step, the

Process Execution component utilises

functional components of the service

organization FG.

C.1.2.1

Run application After resolving IoT Services, the respective
services are invoked. The invocation of a
service leads to a progressive step forward in
the process execution. Thus, the next
adequate process based on the outcome of a
service invocation will be executed.

C.1.2 Process Modelling and Execution FCs

C.1.2.1 Use Cases

The Process Execution diagram (see Figure 116 ) illustrates how a process
model is created by a modelling application and then serialized and deployed to
different execution platforms. The Isis Platform and Real World Integration
Platform (RWIP) are outlined as concrete examples, as these execution
platforms are used as background IP in the IoT-A project.

The use cases in the Process Execution component typically follow this usage
pattern:

1. A domain expert starts with modelling a business process in a
   dedicated modelling application. While such an application for
   modelling IoT-aware processes is not strictly part of the IoT-A
   Reference Architecture, IoT-A will provide a respective tool within
