I am trying to figure out how to get hold of the URL (using absolute_url I presume) of a folder with a property called "sehs_root_folder" set to "yes". Have a look at "ZopeFind" (it is the function implementing Zope's "find" tab). It is documented in the Object Reference (--> zdp.zope.org), maybe in the Zope 2.2 help system, too.

You need to use a relatively new Zope (2.2.1), because older Zope installations raise unjustified "Unauthorized" exceptions due to a bug in "ZopeFind". Dieter
