If you can't actually describe the subtleties to other people in a way
that makes sense to them, then you have failed to do what you set out to
do by introducing the difference in the first place, because it is
But if you can describe it to people, then with a suitable structure, I
am sure it is possible to describe it to machines as well, so that they
can do something useful with it even if they haven't been programmed to
every last nuance. Not least, to offer it on menus as a possibility
(together with a human readable description or pointer thereto), and to
render it as if it were something very similar if that makes sense to
the person who introduced it.
The key thing is the knowledge is centralised and that it can offer some
upward compatibility in the face of rapid and anarchic change.
Can I suggest people look at by TagCentral proposal from SOTM10, slides
and video linked from here:
where I thought about this in quite some detail.
