Part 3 Basic attributes of data
elements
• Defines a set of basic attributes for
specifying data elements
• A number of attributes have to be specified
to facilitate a common understanding
between users and owners
Uses
• the definition, specification and contents of
data element dictionaries;
• the design and specification of applicationoriented 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.
