Depends on what you want. If we define a URI namespace of "CycKB", then
it's trivial--each constant has a unique name within the KB which could
be used in a URI. This would address Cyc constants in the abstract
without reference to a particular Cyc instance.

If you want to point to constants in a particular Cyc *instance* then
you should be able to use normal URLs where the base is the URL of the
Cyc server--not sure off the top of my head how you'd refer to a
particular constant but there must be a way (if there's not already a
defined URL syntax for it, one could write a little CGI script to
provide a suitable URL syntax).

As far as I know, the only *authoritative* Cyc KB is the one maintained
within Cyccorp, but that is not accessible to the world at large.

Cheers,

E.
