<snip Python example>

You're missing the point -- the vocabulary is *not* software, and Python
is *completely* the wrong place to define it:  it is *pure* policy.  THe
fact that you are administering all the sites you build blinds you to
this fact.

My examples move the definition of the vocabulary out into integrator /
administratof land, which is where they belong.
