I got one response to my inquiry from Sandra (SBCR): "At my work one of the systems we use is Drupal, what has a very good interface for you are asking. I am not sure if you can see an example in their website www.drupal.org." The responder posted some screen shots with examples of how the interface works; it allows you to build a tree-type of structure using a GUI, creating elements at the root, and subsequent sub-elements by specifying the parent. If anyone wants details of this post, complete with screen shots, I'll be happy to forward the information.
