This high level description much resembles "Products.PortalTransforms",
a transformation package used in a "Plone" context.
This package is targeted towards "MIME type" based transformations,
i.e. input objects have a "MIME type" and you specify the target
"MIME type". A transform registry knows about the available
(elementary) transformations and determines a chain of transformations
to achieve a desired one.
