Supported Metadata Structures
In this section, the metadata items (and sequence of metadata items) are written in table form where metadata type constants are in the shortened form. For example, LEVEL_START should be treated as IG_METAD_LEVEL_START, UINT32 as AM_TID_META_UINT32, RAW_DAT as AM_TID_RAW_DATA, etc.
See also Working with DICOM Metadata.
AT_DATALIST_ITEM Metadata Structure ValueType and Value Elements
Here are possible combinations of ValueType and Value elements of AT_DATALIST_ITEM ImageGear metadata structure:
