Models at REST or modelling RESTful interfaces for the Internet of Things

We present a first approach to model complex IoT systems with sensors and actuators in UML models and then to generate RESTful interfaces from these. As shown for software development in the embedded domain, high-level models can significantly improve productivity. In particular, we model the composition of resources to structure IoT devices in an hierarchical way and model the behavior of actuators as state diagrams. From these models, we show how to generate rich RESTful interfaces for the discovery, reading and manipulation of resources for the Internet of things.
