In the Sensing Entities Data Model events or sensor data are called "observations". Before a sensor is able to push an observation to the server it needs at least a 'Thing' and a 'Datastream' entity. This has to be created beforehand. One 'Thing' might have different 'Sensors', one 'Location' or many 'HistoricalLocations'.
