  The Roadmap is performed in the context of a Ph.D. research in collaboration
between the Experimental Software Engineering Group, from the Systems
Engineering and Computing Program of the Federal University of Rio de Janeiro
(COPPE/UFRJ) and the Laboratory of Industrial and Human Automation Control,
Mechanical engineering and Computer Science (LAMIH UMR CNRS 8201) in the
Universit\`e Polytechnique Hauts-de-France (UPHF).
  The Roadmap resulted from an investigation on the particularities of IoT
applications. It is the concrete organization of the concepts and evidence
gathered from different experimental studies. It comes to support the
definition of IoT software systems, with specific items for the project team to
discuss and define the essential aspects related to the specifying, designing,
and implementing an IoT application.
