A diagram of the relations among these applications is shown in Figure 2 . For example, a view presented to a depositor submitting X-ray crystallographic data is different from the view for depositing NMR data.
Annotation uses still other views which include an expanded set of data items.
Thus, depositors and annotators see only those data items required for their specific tasks. It also uses the dictionaries to display the sets of acceptable data item values. It also checks nomenclature and orders atoms in a standard order. In data processing, two views of the data are applicable. The Depositor view displays a minimum set of data items that are captured from the depositor.
