This is where I get lost - my Unbrako catalogue does not make any
mention of links when I buy a box of M5 screws. I've just got the box
out and checked and try as I might I cannot get the screw to do anything
remotely resembling following a link. I cannot even find such a link in
a car stuffed full of microprocessors. Is this because General Motors
and Unbrako haven't bought into the Grove paradigm?

Or do you mean that the grove takes you from some internal (computer)
model of the thread to a (computer) model of the procedure for screwing
without an intermediate document format?

What I have still failed to grasp about groves, is what is missing? Why
aren't we all using them?

By this I mean, what work needs to be done in the real world to start
the ball rolling. Does some enabling code need to be written (parser,
compiler, class definition or whatever)? Does a notation need to be
developed and formalised? Does an ISO, ANSI, IEC, IETF, W3C or whatever
task force need to be appointed to make it happen? Or do we all simply
need to think groves while designing whatever we were going to design
anyway?

I have a real application now where I am puzzling over the best way to
express links between objects which sit very well in a hierarchical
tree. Some of these objects are XML documents, while some are properties
of other devices. Where should I start applying groves to this problem
if at all?
