6.7 Representation Set Representation

Representation set representations (Figure 6.7-1) are an indexed assemblage of individual representations. The representation index given is internal and defined in the context of a particular representation set interpretation instance. This representation index is implicit. It follows the order on which the representations are given in the XML instance by the software writer. This representation index is used in the non-sealed surface framework, sealed surface framework, and sealed volume framework.

Representation set representations are used to group together individual representations into a “bag” of representations. These “bags” do not imply any geologic consistency. For example, you can define a set of wellbore frames, a set of wellbore trajectories, and a set of blocked wellbores.

If the bag contains homogeneous individual representations, the "isHomogenous" Boolean may be set, and then the reader software need only read the first individual representation to understand the kinds of individual representations that are gathered in the set.

The representation set representation is also the parent class of the framework representations. Because the framework representations inherit from this class, they inherit the capability to gather individual representations into sealed and non-sealed surface framework representations, or sealed volume framework representations. The representation index is used to define the contact patches.
