14.7.1.1 IndexableElements

For Standard	RESQML v2.0.1

Indexable elements for the different representations. The indexing of each element depends upon the specific representation.

To order and reference the elements of a representation, RESQML makes extensive use of the concept of indexing. Both one-dimensional and multi-dimensional arrays of elements are used. So that all elements may be referenced in a consistent and uniform fashion, each multi-dimensional index must have a well-defined 1D index.

Attributes below identify the IndexableElements, though not all elements apply to all types of representations.

Indexable elements are used to:

attach geometry and properties to a representation.
identify portions of a representation when expressing a representation identity.

construct a sub-representation from an existing representation.

See the RESQML Overview Guide for the table of indexable elements and the representations to which they apply.
