Variant values shall be encoded as a JSON object with the fields shown in Table 30.
Table 30 – JSON Object Definition for a Variant
|
Name |
Description |
|
Type |
The Built-in type for the value contained in the Body (see Table 1) encoded as JSON number. If type is 0 (NULL) the Variant contains a NULL value and the containing JSON object shall be omitted or replaced by the JSON literal ‘null’ (when an element of a JSON array). |
|
Body |
If the value is a scalar it is encoded using the rules for type specified for the Type. If the value is a one-dimensional array it is encoded as JSON array (see 5.4.5). Multi-dimensional arrays are encoded as a one dimensional JSON array which is reconstructed using the value of the Dimensions field (see 5.2.2.16). |
|
Dimensions |
The dimensions of the array encoded as an JSON array of JSON numbers. The Dimensions are omitted for scalar and one-dimensional array values. |
For the non-reversible form, Variant values shall be encoded as a JSON object containing only the value of the Body field. The Type and Dimensions fields are dropped. Multi-dimensional arrays are encoded as a multi dimensional JSON array as described in 5.4.5.
