Thanks.

P.S.
I think OpenCyc has two different redirections.
If you use their Concept Browser,
you get a nice, human-readable display.
But if you use wget, you get an OWL file.

I don't know what the logic is, but I should get further
details soon. I'm joining Cyc Foundation, and expect
to work closely with the implementers.

There has been a lot of discussion in the W3C email group
about content negotiation -- letting the user choose
what form of info. is returned.

Richard,

Good question. The guy who did our messaging facilities obviously felt
that redirections
should be observable by a program, and following redirections ought to be
at the program's
discretion. Personally I am more of a high-level abstraction kind of
person, I might be
inclined to agree with you. Let me think about it a bit; I'll probably
post a message about it
on the unicon-ldif mailing list and see what other folks think.

Cheers,
Clint

Should Unicon's open() function follow URL redirections?

Here's a sample of what I see when I try to access
OpenCyc Web Services.
(used "wget" when "open" failed)
