A data structure that communicates data for a particular series. The fields in the data structure are:
SeriesUID : UID - The UID of the series. For DICOM SOP Instances this is the value of the Series Instance UID (0020,000E) Attribute.
ObjectDescriptors : ObjectDescriptor - An array of ObjectDescriptor data structures listing data existing in this series (within the enclosing Study, within the enclosing Patient).
Most DICOM Composite SOP Instances would be identified by objectDescriptors at the Series level.
