Improved RDF support in new Protege-2000 release

We have just released Protege-2000 version 1.4 with greatly improved
support for working with RDF.  We have rewritten our RDF backend so
that it now uses Sergey's parser to both load and save RDF.  This
should fix a number of compatibility problems that our users
encountered with our previous "experimental" RDF support.  In
addition, we now have support for properties as "first class
citizens".  This allows users to work with RDF in Protege in a much
more natural fashion than was previously possible.

Protege-2000 is an open-source graphical editor for knowledge-base
systems which has been adapted to edit RDF.  Additional information
