You need to provide more information of your description to get some 
specific hints. The other day a had a xml file containing a business 
object model with hierarchy and relations. Then I wrote a code generator 
to build a module with Python classes for each business item. The code 
generator created properties for lazily resolving relations modelled via 
ids in the database and stuff like that. This was very straightforeward 
using a simple print statements like the following:

print "class %s(object):\n" % class_name
print "    def __init__(self, %s)" % constr_arg
...

Cheers,

Jan
