Technical Specification D3.2 – SensorThings API – Sensing
In this issue
The SensorThings API provides an open, geospatial-enabled and unified way to interconnect the Internet of Things devices, data, and applications over the Web. It is an open standard, meaning it is non-proprietary, platform-independent, and perpetual royalty-free.
Although it is a new standard, it builds on a rich set of proven-working and widely-adopted open standards, such as the Web protocols and the OGC Sensor Web Enablement (SWE) standards, including the ISO/OGC Observation and Measurement data model [OGC 10-004r3 and ISO 19156:2011]. That also means the sensorThings API is extensible and can be applied to not only simple but also complex use cases.
This report provides a standard way to manage and retrieve observations and metadata from heterogeneous IoT sensor systems. It follows the REST principles, the use of an efficient JSON encoding, the use of MQTT protocol, the use of the flexible OASIS OData protocol and URL conventions.
