| A : SSN | The SOSA and SSN ontologies are proposed by the W3C. SOSA is the core subset of SSN, sufficient for our needs and easier to use than full SSN. They provide descriptions of Sensors, PropertyOfInterest, and Observations: a sensor observes some property of an object (FeatureOfInterest) and yields a Result. Actuators will not be used for us. | Les ontologies SOSA et SSN (Semantic Sensors Network, et Sensor, Observation, Sample, Actuator) sont proposées par le W3C. SOSA est le noyau de SSN, plus simple, et suffisant pour nos besoins. Il permet de décrire les capteurs (Sensor), les Observations (acte d'observer ou de mesurer), les valeurs (Results) de la grandeur ou propriété observée (ObservableProperty) d'un objet (FeatureOfInterest). Nous n'utiliserons pas les Actuators. |

| KLS2 proposal | Sensor data: time series
For the large amount of data produced by our usual sensors (pressure, temperature, etc.) it is not realistic to encode each measure by a class instance. We propose to keep the data in a textual format close to the provider generated data (.cvs, .txt), with entities specificaly describing the metadata of each of these time series. The time-series class may look like: |
Données de capteurs: séries temporelles
