There are a large number of Internet of Things (IoT) devices that transmit information over the Internet, each with a different data format to denote the same semantic concept. This often leads to data incompatibilities and makes it difficult to extract the knowledge underlying that data. The only way to close this gap is to establish a common vocabulary in order to achieve interoperability between different sources and semantic data integration.

This is the main goal of our proposal: to specify a general semantics for IoT sensing that allows the management of data between gateways, nodes, and sensors in a homogeneous way. Our proposal builds upon the joint Semantic Sensor Network and Sensor-Observation-Sample-Actuator (SSN/SOSA) ontology.
