Re: OWL support

Hi,

you should use the functions in the PLI (PowerLoom interface) package
for this purpose (they are documented in the manual).  For example, to
find concepts you look for instances of the class CONCEPT.  In Lisp:

STELLA(10): (consify (pli:s-get-concept-instances "CONCEPT" "PL-USER" NULL))
(|c|FLOAT |c|MODULE |c|USER-THING |c|INTERVAL-CACHE |c|INTEGER |c|PROPOSITION |c|CONTEXT
 |c|STRING |c|BINARY-RELATION |c|FRAME-PREDICATE ...)
STELLA(11): 

You can then use other PLI functions to figure out what module the
concepts are in, their name, etc.

Tom Russ has written some preliminary OWL translation support which
should help with this task as well (once we release it :-)
