How to store MetaData that descibes IOObject

Hello,
I have a problem with storing my own metadata which describes image. What should I do, to store these metadata.
In SimpleIOObjectEntry class is method for storing:
public void storeData(IOObject data, Operator callingOperator, ProgressListener l) throws RepositoryException {
if (l != null) {
l.setTotal(100);
l.setCompleted(10);
}
MetaData md = MetaData.forIOObject(data);
// Serialize Non-ExampleSets as IOO
OutputStream out = null;
...
...
And it calls:

public static MetaData forIOObject(IOObject ioo, boolean shortened) {
       MetaData result;
       if (ioo instanceof ExampleSet) {
           result = new ExampleSetMetaData((ExampleSet)ioo, shortened);
       } else {
           result = new MetaData(ioo.getClass());
       }
       result.annotations = new Annotations(ioo.getAnnotations());
       return result;
   }
This creates new MD with no reference to IOObject, so fields have default values. Can you change it to:

public static MetaData forIOObject(IOObject ioo, boolean shortened) {
       MetaData result;
       if (ioo instanceof ExampleSet) {
           result = new ExampleSetMetaData((ExampleSet)ioo, shortened);
       } else {
           result = new MetaData(ioo);
       }
       result.annotations = new Annotations(ioo.getAnnotations());
       return result;
   }
Now I realized, that it won't help.

Or is there another solution?

Thank you in advance for your reply.

Best,
Vaclav

    Hi Vaclav,

    currently this is not possible. I've created an internal ticket with a proposed fix for this.
    If it is accepted it will be possible with the next release (or a up-to-date development version) of RapidMiner.
    I will inform you when this is possible.

    Best,
    Nils
