Organizing Principle: Time
A Time Related aggregate organizes data temporally, rather than spatially, where the <Time Constraints Data> on each branch specifies a different time period, such as
- a <Time Point>
- a <Time Interval>
- a <Time Of Day>
- a <Season>
For example, a polygonal representation of a forest might use different texture maps, foliage density properties, and so on for different seasons of the year.
See the atmospheric portion of Advanced Application of the DRM for a detailed discussion of the uses of time organization as it relates to forecast data.
