-Support arbitrary layout of Groups and Datasets within an HDF5 file structure
-Different frames can be stored in different datasets based on an NDAttribute value
-Provides a mapping between an NDAttribute name to a dataset name for storing per frame metadata in datasets
-Arbitrary key-value pair constraints can be attached as HDF5 Attributes to any HDF5 group or dataset. Values can be scalar or arrays of any type.
-NDAttribute values can be stored as one value per frame or one value per acquisition sequence. If the latter, can specify whether data is captured at the beginning or end of the acquisition.
