[Zope] Adding properties to all objects of a certain type

[Cornelis J. de Brabander]

I would create a DTML method that wraps the manage_addProperty method like
this and view it by pressing the 'view' tab (tested):

<dtml-in "objectValues(['Folder'])">
 <dtml-unless reviewed>
  <dtml-call "manage_addProperty('reviewed',1,'boolean')">
 </dtml-unless>
</dtml-in>

You should expand this to meet your specific needs.

Of course the proper way to do things such as this is by means of a Python
script, but to my disgrace I'm still a lot more familiar with DTML than with
Python
