While using Mycore with cascaded object structures (an object can have a parent object, that have a parent object again. an so on...), a export of the whole structure is required.
For example: The system stores a structure like
journal ->HAS_CHILDREN-> volumes ->HAS_CHILDREN-> issues ->HAS_CHILDREN-> articles .
It should be possible to export the book and automatically all containing children.
The Mycore command "export object ..." could become a parameter that specifies if export have to be hierarchical or not. Example: "export object hierarchically TRUE|FALSE"
