Grouping datasets in a series (ie. parent/child relation)¶
In some situations, a dataset is part of a temporal or spatial collections of records which could share the same specification for example (eg. Land cover for different years). To group this set of records a general description of the collection may be done in a parent metadata which is then attached to each datasets of the serie.

Parent/child relations can be set on ISO19139 and Dublin Core records. In ISO19139, the link to a parent record is encoded in the child record using the following:
<gmd:parentIdentifier> <gco:CharacterString>78f93047-74f8-4419-ac3d-fc62e4b0477b</gco:CharacterString> </gmd:parentIdentifier>
Parent/Child relation in ISO19139 may also be encoded using aggregates (see Other types of resources (eg. sensor, publication)).
When creating such relationship, users will be able to navigate between the records in the search and record view.
