Taking into account that creating content objects can be done manually in
python, i'd use a view like this on the container of the new object:


predefined={
   'set1':{
      title:'something',
      otherfield:'foo',
      [...]
   },
   'set2':{
      title:'something else',
      otherfield:'bar',
      [...]
   },
   [...]
}

class CreateView(BrowserView):
   def __call__(self):
      if 'create' in self.request.form:
         if 'paramset' in self.request.form:
            paramsetname=self.request.form['paramset']
            if paramsetname in predefined:
               newobj=MyClass(**paramset)
               name=INameChooser(self.context)('',newobj)
               self.context[name]=newobj

In this case the view could i.e. react to some html-form which presents a
<select name="paramset" ...> , returning either 'set1', 'set2' , [...] .
