6 Representations (Shared Concepts)
|For Standard||RESQML v2.0.1|
A representation has two distinct and complementary roles in RESQML:
- It is an important component of the feature/interpretation/representation/property knowledge hierarchy where it corresponds to a 3D modeling expression of a feature that was initialized at the beginning of a business process (as explained in Section 5.1 Features, Interpretations, Representations , and Properties ). For example, the same horizon feature-interpretation can have a 2D grid representation or a triangulated set representation.
- It supports the geometry and properties of data objects in RESQML. The geometry of a representation is contained within the representation, while properties may be attached to the representation. Each property is “attached” to the indexable elements of a representation, which may be as simple as the nodes on a single triangulated surface or as complex as the cell, nodes, faces, pillars, coordinate lines, columns, etc., for a 3D grid.
All representations share some key concepts, which are explained in this chapter. For more information on these related topics, see the indicated chapter:
