[Zope] Object as subobject

[Sin Hang Kin]

I am making a web with bibliographic catalogues. I have the person objects
which is referred by the bibliographic objects in various places : author,
editor, subject etc. I have made a zclass for person which simply have their
name, title, birth, etc. I intent to place them all in a folder say :
authors

I wish to implement the bibliographic record as zclass, but I do not known
how to let refer to the person object in this zclass.
