+== Overview ==
+
+OAIPMH Harvester in !GeoNetwork needs to be enhanced to support the following:
+
+ * '''Object harvesting''': In recent times !GeoNetwork has moved from supporting ISO19115/19139 metadata in the form of a 'record' to supporting a tree based hierarchy of ISO19115/19139 metadata 'objects'. The diagram below shows a typical hierarchy:
+
+The mechanisms for handling these relationships are part of the ISO standard. They can be explicit in the form of an xlink that refers directly to the related metadata object:
+
+{{{
+}}}
+
+Or implicit by including the UUID of a related metadata object as content in an element. Here is an example of a parent record UUID in the content of the parent identifier element:
+
+{{{
+}}}
+
+And another example of a sibling relationship between a dataset metadata record and a project metadata record (uuid: urn:marine.csiro.au:marlin:project:187):
