. . . unless you have a universal data structure, designed so that "what you
want to do with" the information is already built in.

The CTP universal data structure means you can eliminate the task of
devising the physical data structure.  Just declare contexts that act as
conventions for how you will represent "services."

Then, until the world comes around, you can write export routines that
deliver the information to other systems in XML and RDF form.
