At the moment there are no such collections but it would be nice to have
them. I would need them too for the TM4J ozone binding (a topic map
implementation). So, we could start a subproject of ozone for such
collections (?).

And IMHO it richs this goal. In TM4J we store a complete topic graph in ozone
which works quit well.
