Concepts

For detailed descriptions of concepts and implementation of the data model we refer to the publications of de Bakker et al (2017) and de Jong and Karssenberg (2020). You can also find more detailed informatio about the concepts on the LUE documentation page.

The data model uses the following terminology:

Phenomenon

In the conceptual data model, the concept phenomenon is used to describe a concrete or abstract constituent of the system that is being modelled. A phenomenon contains one or more individuals (objects).

Domain

A domain is the area and time period for which a property exists, for each object.

Property

A property is a particular attribute of a phenomenon.

Property set

A property set can be thought of as a set of properties sharing a particular spatio- temporal domain, i.e. the area and time period for which the property exists.

Value

The value allows for the modelling of spatial and temporal variation within a domain.
