Thanks for the reply :) python+django make everything easier than java, but I don't think there is any nice clean way of modelling something like this.
It might be easier to have each specialized model inheriting from a generic item class (through django), then listing each seperately or performing a search across the multiple models ... ... or a model method like item_get_extras() that searches known specialization models for foreign keys ... hrm ~ no nice way of doing this it seems.
