Re: Interpretation of RDF reification


Common Logic is still in the FCD stage at ISO.  Some
people are developing tools based on it, but I don't
know of any that are commercially available right now.

However, the Common Logic Interchange Format (CLIF) has
a large overlap with the Knowledge Interchange Format (KIF),
which has been widely used since the mid 1990s.  Almost
anything done in KIF can be moved over to CLIF with minor
modifications (and some with no modification at all).

I know a couple of groups who have used Prolog to translate
RDF and OWL into other formats.  At VivoMind, we have used
Prolog to handle very large RDF and OWL files that cause
Protege to choke.  Prolog is lightening fast for reading
such files and converting them to other formats (such as
CLIF and CGIF).  Our tools for using the results, however,
are still in alpha and beta stages.

One of the primary tools we have been developing at VivoMind
is the Flexible Modular Framework (FMF).  See the following
paper for the basic idea:

Our plans are to make an open source version of the FMF
freely available and to make a business of developing and
licensing modules to plug into the FMF.  However, we are
still working on the commercial version.

The short answer to your question is that I don't know
anybody who develops stuff to play with, and the people
I do know are up to their ears in work from paying
