||A highly expressive relational reference language is
developed that covers most possibilities to use relations in practical
applications, which is designed to work in a heterogeneous setting. This
language is intended to serve a variety of purposes. First, it shall
allow to formulate all of the problems that have so far been tackled
using relational methods with full syntax- and type-control.
Transformation of relational terms and formulae in the broadest sense
shall be possible as well as interpretation in many forms. In the most
simple way, boolean matrices will serve as an interpretation, but also
non-representable models as with the RATH-system may be used. Proofs of
relational formulae in the style of RALF or in Rasiowa-Sikorski style are
aimed at. Also some basics for partiality structures are included that
allow to model degrees of information or degrees of availability of
composite objects to be modeled.
