Subclass

• None.

Definition

An instance of this DRM class specifies a single data element for a cell within a <DRM Data Table> instance by providing:

1. an EAC, 5.2.7.23 Index_Code, or 5.2.7.54 Variable_Code, identifying the meaning of the cell data element,
2. a value_type that specifies its storage type, and
3. an EUC and ESC that together specify the scaled unit of measurement if the EAC is numeric.

The complete structure of a cell within the given <DRM Data Table> instance is described by the complete ordered set of <DRM Table Property Description> components of that <DRM Data Table> instance.

Additional information about the cell property being described, where such information is to be applied throughout the scope of the <DRM Data Table> instance, such as sentinel values and tolerances, is specified by attaching <DRM Property Characteristic> components to the applicable <DRM Table Property Description> instance(s).

The meaning field specifies the meaning of the <DRM Table Property Description> instance.

The value_unit field specifies the unit of measurement of the <DRM Table Property Description> instance.

The value_scale field specifies the scale applicable to value_unit.

The value_type field specifies the storage type of the <DRM Table Property Description> instance.

The component_data_table_ecc field specifies the ECC used to identify the table type of a component or library <DRM Data Table> instance. It is only used if the <DRM Table Property Description> instance is describing an index that refers to a <DRM Data Table> instance. This, in turn, is only the case if meaning = {INDEX, {DATA_TABLE_COMPONENT}} or meaning = {INDEX, {DATA_TABLE_LIBRARY}}

Constraints

• <DRM Table Property Description> constraints
• Publishable object

Example(s)

• Consider a <DRM Property Grid> instance containing sound speed data for a body of water. For each spatial location in the grid, the corresponding cell in the <DRM Property Grid> instance specifies the properties of EAC_SALINITY, EAC_MEAN_WATERBODY_TEMPERATURE, and EAC_WATERBODY_SOUND_SPEED at that location as depicted in Figure 6.339:
