Thesaurus support in GeoNetwork allows:
Metadata editing: controled vocabulary on the metadata editing interface for ISO and Dublin Core
Administration interface allows import/export/creation/browse thesaurus
Search interface: a list of keyword is proposed for the keyword criteria
On a node, thesaurus types could be defined as:
External: When a thesaurus is imported, it is flagged to ”external” which means that users are not allowed to edit the thesaurus. This thesaurus is managed by an external organisation.
Local: When a thesaurus is created, it is flagged to ”local” which means that users are allowed to edit the thesaurus.
