ScopeScope

Describes business rules for the registration of data elements and their attributes in a registry, to assist in consistently establishing good quality data elements.

Based on the model of a data registry described in ISO/IEC 11179, Part 3.

Helps to achieve metadata content consistency through procedures and examples.
