Definition |
An object of this DRM class specifies a reference to an n-1 dimensional 'slice' of an n-dimensional <DRM Property Table> in a <DRM Data Table Library>, where N is the number of <DRM Axis>s of the <DRM Property Table>. <DRM Property Table Reference> exists primarily to allow a data provider to select a set of parameters from a standard <DRM Property Table> containing an indexed collection of alternatives. Since only one <DRM Axis> requires a specific 'tick mark' to be specified, <DRM Property Table Reference> specifies the axis_type of the <DRM Axis> to be matched, and the index_on_axis specifies the 'tick mark' on that <DRM Axis>. |

Example(s) |
· A <DRM Geometry> may have a reference with table_type TABLE_THERMAL_VALUES to access the thermal value for the <DRM Geometry>. · A <DRM Feature> may have a reference with table_type TABLE_MOBILITY_INDEX to access mobility properties of a road or a terrain surface. |
