Is there an Undo/Versioning solution based on Magritte?

Hi all, I'm trying to implement a way to have versions of the contents entered through a form so I can revert the object models to an early state, very much like the page history edits in Wikipedia, but with more fields than just the text content. This solution should provide a feature to store the contents not only of the descriptions in the container, but also descriptions contained in referenced descriptions (via MAReferenceDescription). I'm about to write my own, but if there is something out there, I would like to see if it fits our needs, or could be easily modified. Regards! Esteban A. Maringolo
