    ABSTRACT:: In this paper we present a mechanism for translating
               information in heterogeneous digital library environments. We
               model information as a set of conjunctive constraints that
               are satisfied by real- world objects (e.g, documents, their
               metadata). Through application of semantic rules and value
               transformation functions, constraints are mapped into ones
               understood and supported in another context. Our machinery
               can also deal with hierarchically structured information.
