I want to add certain properties to objects of a certain type without having to use the web interface (there are too many of them)... e.g. I would like to add the following properties to all folders: title_en (string), nickname (string), nickname_en (string), template (string), reviewed (boolean) and the following to all DTML-Documents: lang (string), nickname (string), template (string), keywords (string), author (string), reviewed (boolean) A few documents and folders on the site have these properties already (is this a problem?). And after I add these properties to all documents and folders how do I get Zope to add them to new ones automatically? I want to keep everything as simple as possible... i.e. no Z Class to worry about when upgrading, etc. Concrete examples would be appreciated (theoretically I know it is possible with Zope considering what I have been able to do up to this point as a greenhorn!). Thanks, Carl.
