IUDX one of the members of the Smart Data Models Steering board has contributed actively to the new data model in the Environment subject.
It is relevant the Time Series Aggregation (TSA) properties which allow storing the average of the parameter during a period, their maximum and minimum, and their instant value. It has been generalized and makes it available in the shared schema for the subject.
The new data model in the datamodel.FrictionlessData subject
It has been extended the data model of AirQualityObserved in the datamodel.Environment Subject.
With the property, AirQualityIndex is the numerical value for the Air quality. This value is frequently transformed into qualitative scales (good, quite good, etc)
The data model WaterQualityObserved has been expanded to include 3 new properties:
Additionally, the data model of WaterQualityObserved has been moved from the dataModel.Environment repo to the dataModel.WaterQuality subject.
In order to preserve the relationship with the SmartEnvironment domain the subject dataModel.WaterQuality has been linked to it.
There are two new data models ElectroMagneticObserved and IndoorEnvironmentObserved
ElectroMagneticObserved. The Data Model is intended to measure excessive electric and magnetic fields (EMFs), or radiation in a work or public environment according to the level of exposure to electromagnetic fields on the air. The frequency of the Hertzian waves is conventionally lower than 300 GHz, propagating in space without artificial guide. They are between 9 kHz and 300 GHz.
IndoorEnvironmentObserved. Observation of air and climate conditions for indoor environments.
Located in the Subject Environment
There is a new data model RainFallRadarObservation. The Data Model is intended to measure the water slides on a predefined area by a set of 4 Location represented by a Geo property format.
Located in the Environment Subject.
There is a new data model PhreaticObserved is intended to measure, observe and control the level and quality of groundwater at a given time (T), by a fixed or mobile monitoring system. Depending on the device used, it is also possible to measure the quality of water such as its electrical conductivity, its salt content, its temperature, etc. In this case, the values measured are processed by the Data Model `WaterObserved` and `WaterQualityObserved`. Additional Information about Attributes: For attributes dedicated to water, a MetaData attribute can also be used. it contains the `TimeStamp` in seconds, the `qualification` and control `status` of the measurement”.
Located in the Environment Subject
There is a new data model IndoorEnvironmentObserved for observations of air and climate conditions for indoor environments.
It belongs to the Smart.Environment domain in the subject dataModel.Environment.
Now, this data model AirqualityObserved can be used for indoors and outdoors measurements.
Check it out in the environment Subject.
This is the PR.
