The M3-lite is a taxonomy that enables testbeds to semantically annotate the IoT data produced by heterogeneous devices and store them in a federated datastore such as FIESTA-IoT. In this taxonomy, we classify devices, the domain of interests (health, smart home, smart kitchen, environmental monitoring, etc.), phenomena and unit of measurements.

M3-lite taxonomy is designed for the EU H2020 FIESTA-IoT project. It is a lite version of M3 ontology. M3-lite contains taxonomy for various QuantityKinds (commonly known as physical and environmental phenomena), Unit of measurements, different types of sensor and different types of domain of interests. M3-lite has evolved to serve the purpose of several testbeds that want to be part of federation provided by FIESTA-IoT. Most relevant testbeds integrated using M3-lite are EU FP7's SmartSantander testbed, UniS's (UK) SmartICS testbed, Inria's (France) Soundcity/Ambiciti testbed, KETI's (South Korea) Mobius testbed and EGM's (France) 4G testbed. More information on the above testbeds along with those that have joined at the FIESTA-IoT platform is available via http://fiesta-iot.eu/index.php/fiesta-testbeds/. Intially, this taxonomy was a light weight version of M3 ontology and since 2016 has found its own separate way. We further acknowledge, testbed provider such as SmartSantander, UniS, KETI, Inria, and other open call testbeds for their valuable comments. Please report any errors to rachit.agarwal@inria.fr.

Ionising radiation is radiation that carries enough energy to free electrons from atoms or molecules, thereby ionizing them. Gamma rays, X-rays, and the higher ultraviolet part of the electromagnetic spectrum are ionizing, whereas the lower ultraviolet part of the electromagnetic spectrum, and also the lower part of the spectrum below UV, including visible light (including nearly all types of laser light), infrared, microwaves, and radio waves are all considered non-ionizing radiation.
