But I want to add it also automatically to all new resources created for 
a specific metamodel.

It sounds something like exactly that.

I have a metamodel with a String attribute in some object and a lot of 
complicated child objects. The String is a convenience represenation of 
those child objects and I have a String parser and serializer that is 
able to convert the String into the child object set and vice versa.
So what I wanna do is whenever somebody changes such a String, it should 
trigger my parser and vice versa if any of the child object have 
changed, the serializer should update the String.

Additionally the serialization is dependent on some referenced objects 
somewhere else so I have also to monitor them.

So how can such "self adapting" be done. Sounds like something I could 
also use.

Cheers,
