The logical notion of theory morphism or interpretation (between
theories) may be useful here.  The key idea is to translate from one
language to the other in a way that preserves meaning, specifically,
theorems are preserved under translation.  The translation is
typically specified by a symbol-to-term map.

At Kestrel Institute we use interpretations to refine one
specification to another.  Any data structure in the source spec can
be translated into a data structure in the target spec, and then
operated upon by algorithms in the target.  We are pursuing the use of
interpretations as a basis for ontology translation in the DARPA DAML
project.

Many texts on logic cover interpretations between theories
(e.g. Schoenfield, Enderton).  Originally, they were developed as a
way to study the relative consistency of two theories.

Cheers,
 Doug
