2. 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

3. 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

4. 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.

5. 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.

6. General descriptors • descriptor of attribute obligation • - name M • - definition M • - obligation M • - condition C • - maximum occurrence O • - datatype M • - maximum size O • - character set C • - language C • - comment O

8. Obligations • mandatory: always required; • conditional: required to be present under certain specified conditions; • optional: allowed but not required.(in context of your data of your own registry)

12. Identifying Relational Representational Administrative Attributes that are applicable for the identification of a data element. Attributes that describe associations among data elements and/or associations between data elements and classification schemes, data element concepts, objects, entities. Attributes that describe associations among data elements and/or associations between data elements and classification schemes, data element concepts, objects, entities. Attributes that describe management and control aspects of a data element. Categories of basic attributes
