Data items in this category are as follows:

The bullet (![[\bullet]](/teximages/a1ach2o1/a1ach2o1fi16.svg)
) indicates a category key. The arrow (![[\rightarrow]](/teximages/abch3o1/abch3o1fi527.svg)
) is a reference to a parent data item.
Each value of the _array_data.data data item is a sequence of octets representing a binary image. _array_data.array_id and _array_data.binary_id, taken together, uniquely identify each image. The value of _array_data.array_id is a pointer to _array_structure.id to provide the relationship between the sequence of octets and the logical structure of the image. Since multiple images may have the same logical structure, the purpose of _array_data.binary_id is to ensure that each image has a unique identifier.
