Simply make it a Python reference: class BlogEntry(object): category = None class Category(object): pass entry = BlogEntry() entry.category = Category() Of course, you need to get permissions and interfaces correctly. You might also want to investigate annotations. The following add-on packages are also relevant: http://svn.zope.org/lovely.tag/ http://svn.zope.org/lovely.rating/ You could then build a category implementation on top of tags. We have done this for a large site and it works well.
