5.3.4 Property Level

The property level was set up to easily transfer newly updated properties for a well-known existing representation. (For more information on properties, see 8 Properties .

The property level corresponds to valuating the indexed elements of a representation. The properties (which can also be location properties, i.e., geometry) are in this case attached to a specific topological description. For one specific topological description—if you know the UUID of the representation to which they are attached—you can attach several properties with different time stamps and exchange these properties between different software without exchanging the representations itself--you only need to specify the representation.

For example, if a software package makes a change to a data object at the interpretation level, the software must update the data object's metadata including the "Last Change" element (date and time the data object was last changed) and the "Editor" element (the person or organization that made the change).This type of change management tracking can be used for reevaluation of models and field appraisal management.
