Tree Example, Revisited
The example describes an object - a tree - that has a physical location and a collection of attributes, where the attributes differ depending on whether data model A or B is used to describe the tree.
Consider some DRM class that can specify
- a <Location> instance, specifying the location of the "thing" in the environment
- a <Classification Data> instance that uses EDCS to specify what the object represents (a tree)
- various <Property Value> instances using EDCS to specify properties of the object and the values of those properties
Instances of such a DRM class can be used to define many kinds of objects.
