CEDRIC-IIE is researching rigorous information system (IS) development. Previous work includes translation rules for deriving a B specification from object-oriented diagrams, metamodels of IS UML structural and functional concepts, and a prototype translation tool. Here we outline the traceability needs for a tool to assist in rigorous IS development, and provide meta-structures for the required links among B and IS UML concepts, in the context of existing translation rules and IS UML metamodels.
