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.

Smart water and Smart Environment: Updated WaterQualityObserved in water quality repository

The data model WaterQualityObserved has been expanded to include 3 new properties:

  • BOD: Biochemical oxygen demand (BOD) is the amount of dissolved oxygen (DO) needed (i.e. demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period
  • COD: Chemical oxygen demand (COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution
  • PO4: Concentration of phosphates

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.


New data models for Environment. ElectroMagneticObserved and IndoorEnvironmentObserved

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.

New data model for Environment. Phreatic Observed

There is a new data modelĀ 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”.
