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 the Advanced Application of the DRM tutorial for a detailed discussion of the uses of time organization as it relates to forecast data.
