Property, or Prop, is a domain level module of the Common Semantic Data Model (CSDM). It provides a taxonomy of energy domain properties.
The scope of this module extends also to the definition of units and categories associated with properties, and used for values definition.
| ID | Question in natural language | Example |
|---|---|---|
| cq-1 | What are possible values to be associated with a qualitative property ? | Possible values for a qualitative property include the set of values defined in the category in which it is evaluated. |
| cq-2 | What are possible properties that can be associated with a unit of measurement ? | EUR-PER-KiloW-HR is a unit of measurement that can be used for energySellingprice, EnergyBuyingPrice,... |
| cq-3 | What are possible units for measuring a property ? | Temperature property can be measured in Celsus Degrees, Fahrenheit degrees,... |
A prop:Property is the upper class for the omega-X property taxonomy. It is further distinguished into prop:QuantitativeProperty for properties to which numerical values are assigned (prop:Temperature has as possible values 18, 19,..), and prop:QualitativeProperty for properties with values defined in a category (eg. prop:OperatingStatus has as possible values On and Off).
The evaluation of properties is described in Event and Time Series module, through the ets:PropertyValue class . For dyamic values (chaning over time), a ets:ValueSet is created with the entire set of values, following a ets:TemporalContext. For static values (stable in time), the object property prop:hasPropertyValue enables to indicate one value per property.
Categorical individuals of type prop:Category are used as property values ets:PropertyValue in case of qualitative Datasets.
