Definition

A <DRM Data Table Library> is a derived <DRM Library> containing <DRM Data Table>s that can be referenced or 'instanced' by an object within the transmittal. If the particular <DRM Data Table> is a <DRM Property Grid>, the associating <DRM Geometry> shall have a <DRM Location> that is used as the origin for the spatial <DRM Axis>s in the <DRM Property Grid>, most often a <DRM Property Grid Hook Point>. A (non-spatial) <DRM Property Table> is assumed to provide information that applies to the entire associating <DRM Geometry> or <DRM Feature>. A <DRM Property Table Reference> may be employed to select a (N-1)-dimensional slice from the referenced <DRM Data Table> in the <DRM Library>.

Example(s)

·         A generic seamount could be modeled as a two-dimensional <DRM Property Grid> of such things as the bottom elevation or surface properties. This grid could be 'instanced' multiple places in the environment by means of DRM_Property_Grid_Hook_Points to construct a desired situation for training sonar operators.

·         A table of material properties can be placed in the <DRM Data Table Library> and accessed via <DRM Property Table Reference>s to identify the materials and their properties for objects in the transmittal; e.g., the optical or electromagnetic properties in various wavelength bands.
