* The system tries to load the content object of the MetaClass as defined in the class mapping identified by '''TargetType''' with key values similar to the values of the according XML attribute in the data file. If an object can be found, a reference to this object is set on the MetaProperty named similar to the inner text of the XML element in the mapping file.
* For an import process set '''UseHierarchy=1''' to load a content object corresponding to any parental XML element of the one currently processed.
{{Hint|For each reference mapping specified in the '''<Reference>''' section, the interface will try to read from / create an appropriate XML element. To ignore the reference information during import or if it should not be exported do not include a reference element in this section at all or set '''EvaluateReferences''' to 0.}}
{{Attention|Be aware of the different usage of the UseHierarchy attribute in import / export processes. During export, the interface will try load all objects related to the current exported object via the given relations. To skip the current view parent enable UseHierarchy, this exports all related objects except the view parent. If relational information should not be exported do not include a relation element in this section at all. Nevertheless, certain hierarchical information will always be exported due to the view hierarchy.}}
