SensorThings API
"SensorThings API is an Open Geospatial Consortium (OGC) standard specification for providing an open and unified way to interconnect IoT devices, data, and applications over the Web. The SensorThings API is an open standard, builds on Web protocols and the OGC Sensor Web Enablement standards, and applies an easy-to-use REST-like style." (Open Geospatial Consortium 2016)
