It is also possible to add semantics about the relationships between subrepresentations, even if they come from different representations. The table below describes different identity relationships. This type of relationship is commonly used to identify the contacts between representations in model description, but may also be used to relate the components of a grid (pillars) to those of a structural framework (faults).

Concept |
Definition: A set of subrepresentations or representations): |
|---|---|
|
Collocated (Sub)Representations |
Is Collocated if there is bijection between the simple elements of all of the participating (sub)representations. This implies there is the same number of simple elements. The geometric location of each set of simple elements mapped through the bijection is intended to be identical even if the numeric values of the associated geometries differ, i.e., due to loss of spatial resolution. |
|
Equivalent (Sub)Representations |
Is Equivalent if there is a map giving an association between some of the simple topological elements of the participating (Sub)representations. |
|
Previously Collocated (Sub)Representations |
Were collocated at some time in the geologic past, but not necessarily in the present day earth model. |

Previously Equivalent (Sub)Representations |
Were equivalent at some time in the geologic past, but not necessarily in the present day earth model. |
