== Overview ==

ISO Metadata records can be related to one another in different ways. The mechanisms for handling these relationships are most often part of the standard in the form of specific elements eg. parent-child relationships are handled through the parentIdentifier element and the datasets that a service delivers are handled through the operatesOn element. !GeoNetwork:
 * can index these relationships to support search
 * has services for retrieving a specific set of related records or the entire collection of related records
This proposal adds sibling relationships between metadata records to !GeoNetwork. The elements in the ISO standard that support sibling relationships are the aggregatedInformation element. Sibling relationships types can be specified using an extendible codelist. Sibling records would be displayed under the relationship type. An example of how sibling relations are displayed in the classic interface and the new ExtJS interface is shown below.
