Hi
I'm having an IOObject table with objects instead of just numbers and strings (which is why I can't use ExampleSet) and I need to store it. Only way I can think of is using Repository Access operator, but I'm guessing that's just going to serialize it into file.
Is there a way how to perform object-relational mapping, or any other 'clever' way?
thank you

If you just need to store it, serialization should be fine. Why not ?
If you want to process arbitrary objects within rapidminer, but require a tabular-like access, this thread (http://rapid-i.com/rapidforum/index.php/topic,2917.0.html), especially this post (http://rapid-i.com/rapidforum/index.php/topic,2917.msg11708.html#msg11708) + the ones afterwards may help you.
EDIT: I totally misunderstood your question. Regarding object-relational mapping, as far as I know this is currently not implemented in rm yet. However, these techniques exist, so you *only* have to write your own operators linking the appropriate libraries.
