Your ZClass inherits the methods of its base classes.
You use the base classes methods to access their features.

In your specific case, you would use "manage_changeProperties"
to change the DTML Document properties.
"manage_changeProperties" is defined by "OFS.PropertyManager.PropertyManager".

You can create your own ZClass "view" that does this.

Same as 2)

You just define "Meta Data" or indexes for them.

I do not understand this question:

  "index_html" has nothing to do with interpreting DTML tags.

  If there is an "index_html", then, via the web, you
  can use ".../my_object" and, in fact, ".../my_object/index_html"
  is used. That is all.

  When you want to interpret DTML tags, you will need to somehow
  use DocumentTemplate instances.

You will find in the list's archive a suggestion for converting
DTML documents into DTML methods.
It could be adapted for your purpose.

You may have a look at ZPublisher.Client, too.
It allows to control Zope by external Python scripts.
