RE: [Zope] [ADVANCED] How do YOU guys do many-to-many in Zope without relational?

From: Trevor Toenjes [mailto:zope@toenjes.com]

Allow someone to rename the "title" property, but not change the ID of the Zclass instance (lock the ID once it is created, so users cant rename it). This will retain link integrity.

again this assumes that the id is unique for all of the site. regards Max M
