Records may have thousands of attributes, which can make them unwieldy to view or
edit. For display purposes, attributes are grouped, typically according to their function.
For example, all the metric measurement attributes might be placed into a group called
"Metric Measurements" and the imperial measurements in a group called "Imperial
Measurements". These attribute groups are then placed into larger groups called attribute
tabs. The groups Metric Measurements and Imperial Measurements might be placed into a tab
named "Specifications". These attribute groups are then placed into larger groups called
attribute tabs. The groups Metric Measurements and Imperial Measurements might be placed
into a tab named "Specifications". When a record is opened in an editor, the attribute tabs
are displayed. The tabs can be expanded to show the attribute groups. The attribute groups
can be expanded to show the actual attributes themselves. Each repository has its own set of
attribute tabs and groups. Attribute tabs and groups are defined and maintained by the
system administrator.
