While collaboration on documents has been supported for several decades by a variety of systems and tools, in recent months a renewed interest is apparent through the appearance of new collaborative editors and applications. Some of these distributed groupware systems are plug-ins for standalone word processors, while others have a purely web-based existence. Most exemplars of the new breed of systems are based on Operational Transformations, although some are using traditional version management tools and still others utilize document-level locking techniques. All current techniques have their own drawbacks, creating opportunities for new methods. In this paper the authors present a novel collaborative technique for documents which is based on transactions, schedulers, conflicts and locks.
