\section{Introduction}
The \gls{TOP} paradigm and the according \gls{iTasks} implementation offer a
-high abstraction level of real life workflow tasks. Through an \gls{EDSL} that
-programmers can model workflow tasks. The system will then generate a
-multi-user web service. This web service can be accessed through a browser and
-used to complete these \glspl{Task}. Familiar workflow patterns like sequence,
-parallel and conditional tasks can be modelled. From the \gls{Task} description
-the system will generate an multi-user web application for real life tasks.

-\gls{iTasks} has been shown to be useful in many fields of operation such as incident
-management~\cite{lijnse_top_2013}. Interfaces are automatically generated for
-the types of data which makes rapid development possible. However, while the
-tasks in the \gls{iTasks} system model after real life workflow tasks the
-modelling is very high level. It is difficult to connect actual tasks to the
-real tasks and let them interact. A lot of the actual tasks can be
-\emph{performed} by small \gls{IoT} devices. Nevertheless, adding such devices
-to the current system is difficult to say the least as it was not designed to

In the current system such adapters, in principle, can be written as
\glspl{SDS}\footnote{Similar as to resources such as time are available in
the current \gls{iTasks} implementation} but this requires a very specific
-adapter to be written for every device and functionality. Moreover, this does
-not allow you to build in logic into the device. A lot of the small \gls{IoT}
-devices have limited processing power but can still contain decision making.
-Oortgiese et al.\ lifted \gls{iTasks} from a single server model to a
-distributed server architecture~\cite{oortgiese_distributed_2017} that is also
-runnable on smaller devices like \acrshort{ARM}. However, this is limited to
-fairly high performance devices that are equipped with high speed communication
-lines. Devices in \gls{IoT} often only have \gls{LTN} communication with low
-bandwidth and a very limited amount of processing power and are therefore not
-suitable to run an entire \gls{iTasks} core.
