Several weeks ago I did the same question without an answer. What I found since then is that if you are going to deal with documents whose properties are going to grow and/or change, you must use regular Zclasses, or try to write your own in Python. When you add a property to a Zclass you add it to all the documents built with them. I'd also like to have the kind of feature you talk about. Something like a tool based on the manage_findResult method whose results have a checkbox, enabling to perform several kind of processes over them, like adding, deleting or renaming document's properties. In the meantime this is the code to add properties using dtml-call. Use it within a method at the same folder where your to-change-objects are located. <dtml-call "object.manage_addProperty('thepropertyname', 'the content string', 'type')"> where 'type' is the usual type you find at the edit properties page (string, text, tokens, etc). Be aware that to execute the line you only have to make a "view page" action one single time, and that you won't see any response after its performance.

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.
