Uses

• the definition, specification and contents of
  data element dictionaries
• the design and specification of
  application-oriented data models, databases and
  message types for data interchange
• the actual use of data in communications and
  information processing systems
• interchanging or referencing among various
  collections of data elements.

Definitions
General descriptors Descriptors that enable
data elements to be registered and controlled in
a standard way - in order to achieve
consistency in the exchange of information on
data elements among data element
dictionaries - to enable the comparison of data
elements used in different data management
environments. Basic attributes A
specification of a data element consists of a set
of attributes. Part 3 of the International
Standard specifies a set of basic attributes.
