Cancelling or reversing the effect of a former action is a necessity in most interactive systems. The simplest and most frequent form of this facility is the “undo” command that is available in usual, individual, text or graphic editors. As soon as collaborative work is considered, undoing is more intricate since the notion of a last action is not always meaningful. Within this framework, the so-called “selective undo”, which allows selecting and cancelling any (or rather some...) former action, has received lot of attention. There are some similarities between cooperative work and composite web services: Component web services are concurrently accessed; they may be treated as shared documents for undoing former actions. Among the latest results on undoing in group editors, the transformational model seems suitable for generalization to other kinds of distributed systems. It completely avoids backward state recovery and allows the selection and cancellation of any former operation. We present some relevant aspects of this model, and then some hints on how to transpose it into the framework of composite web services.
