# 6.2.1 Indexable Elements

Topic Version | 1 | Published | 09/11/2015 | |

For Standard | RESQML v2.0.1 |

Table 6.2.1-1 shows the RESQML indexable elements and indicates for which representation or representations these elements are defined. This list of indexable elements is used to:

- Contain geometry within a representation
- Attach properties to a representation
- Identify portions of a representation when expressing a representation identity
- Construct a subrepresentation from an existing representation

Several specialized indexable elements, e.g., hinge node faces, have been included to add higher order geometry to a grid representation, and are not available for other purposes.
