I remember both Rational Rose and TogetherJ CASE tools. Round-trip engineering was supposed to be practiced by both Domain Experts and Programmers each modifying their models and still having them all consistent with each other. But what happened in practice was that only Programmers used them who did not see the utility of updating a UML class hierarchy instead of directly updating the Class itself. That and the exorbitant pricing is why they fell out of favour. It is really a shame because with the explosion of distributed apps using a variety of languages/tools a single uniform interface modeling all aspects of the software is sorely needed. PS: Came across the book Software Visualization - Visualizing the Structure, Behaviour and Evolution of Software by Stephan Diehl which seems to provide a good survey of the field.
