Re: Looking for description of PowerLoom built-in ontology

Hi Cameron,

as you described, the coverage in the manual is not complete and
focuses on the most important and "official" concepts and relations in
PL-KERNEL.  However, most of the things you asked about do have
documentation associated with them.

One way to look up documentation is via a query, for example:

STELLA(46): (retrieve (documentation thing ?d))
There is 1 solution so far:
  #1: ?D="The class of all things.  `Thing' is the top-most concept
in the concept hierarchy."
STELLA(47): (retrieve (documentation set ?d))
There is 1 solution so far:
  #1: ?D="This class denotes the mathematical notion of a 'set';
a collection that has no duplicates."
STELLA(48): (retrieve (documentation collection ?d))
There is 1 solution so far:
  #1: ?D="The class of all collections.  This includes all sets,
lists, concepts, and relations."
STELLA(49): 

Another way is to look at the source file in
powerloom/sources/logic/pl-kernel-kb.ste directly.

Literal data types such as STRING, INTEGER, FLOAT, NUMBER, etc. are
currently not explicitly ontologized and are inherited from their
corresponding STELLA classes.  You won't find documentation strings
for those.
