A component ontology in powerloom

Can someone direct me to an ontology of components with attributes, and parameters, etc. (for the purpose of mechanical engineering) that I can use in powerloom? I found something related in KIF (though I am not very sure)- can I use that in powerloom?

Also, what advantages does powerloom have over KIF?

Siddharth,

unfortunately, I can't help you with respect to the component
ontology.  But if you found one represented in some version of KIF, it
should be possible to adapt it without too much work so you can load
it into PowerLoom.

With respect to the second question, PowerLoom is a KR&R system that
allows you to store facts and rules, query them, perform logical
inference with them, etc.  KIF is the language used to represent these
facts and rules.  In a sense, PowerLoom relates to KIF somewhat like
MySQL relates to the SQL language.  KIF is the "Knowledge Interchange
Format" invented in the early 90's at the beginning of the knowledge
sharing initiative.  It is a Lisp-based syntax for first-order
predicate logic.  There are various versions out there such as KIF
3.0, ANSI KIF, SUO KIF and now Common Logic which has KIF as one of
its supported syntaxes.  PowerLoom uses its own variant of KIF that we
sometimes call PL-KIF.  The main difference of PL-KIF to some of the
other variants is that it has various definitional constructs such as
`defconcept', etc., and that it doesn't (yet) support sequence
variables.  As I said in a previous message, given that Common
Logic is a bonafide standard now, we'll work on making the
relationship between Common Logic and PL-KIF more precise.
