Hi All,
In my application I am trying to import a set of data that has a
hierarchical structure. Let's say we have a "Container" node and many
"DataNode" under it.

Currently when I read in my data the mitk::DataNodeFactory will put
all my data objects into individual data nodes that are at the same
level (topmost) of the data storage. As I checked in MITK it is hard
coded to use the mitk::DataNodeFactory in every occasion to import
data. However it would nicer if I could customize this DataNodeFactory
by overriding some of its methods.

So the suggestion is to create a DataNodeFactory factory, that
instantiates a preferred application specific factory. This way the
application level I could register my own type of DataNodeFactory and
the system would use this whenever it is required to load data (and
stuff it to a datanode).

Does this sound reasonable?

Cheers,
Gergely
