A UML-Based Proposal for IoT System Requirements Specification

The paper presents a preliminary version of IotReq, a method for the elicitation and specification of the requirements for an IoT-system. The first task suggested by IotReq is the modelling of the domain, using the UML and following the service-oriented paradigm, then the goals of the IoT-system to build are elicited and specified, again using the UML and extending the domain model, producing a specification of the functional requirements. IotReq also provides preliminary indications for specifying the technological nonfunctional requirements. A case study, the specification of the requirements for a system to support the Genoa's Science Festival is presented too.
