....replaces them with the destination schema for all instances for which the condition is verified. The paper also proposes a migration language for managing instance specific migrations, conceptually similar to our migration language. Other contributions to the area of workflow evolution come from [8,12]. In [12] a complete and minimal set of workflow modification operations is presented. Correctness properties are defined in order to determine whether a specific change can be applied to a given instance. If these constraints are violated, the change is either rejected or the correctness must be ....

....dynamic workflows. Such systems must be uniquely sensitive to a rapidly changing process execution triggered by collaborative decision points, context sensitive information updates, and other external events. The majority of current work addresses relevant issues at modeling and language levels [24, 36, 45, 53, 57, 70] while the relevant issues involving organizational changes appear in [24, 38] A particularly different approach to supporting adaptive workflow (capable of reacting to the changes in local rules and other conditions) has been developed using the notion of migrating workflows) 19] Related ....

....votes per positive from one bait plate, the number of controls satisfied per bait plate, and estimated coverage. 4.2. Adaptation Traditional WfMSs are adequate to support workflows with a defined structure and with no need to account for ad hoc deviations or dynamic extensions at run time [70]. But, recently 66 KOCHUT et al. there has been an increasing demand in developing WfMSs with dynamic capabilities, with a special emphasis to dynamic changes at the instance level. This makes sense since there are in reality very few workflows that are static (i.e. without a need to change their ....

....to an ad hoc workflow, or be aborted. Our solution is in fact a mixture of the first two policies: parts of the workflow are migrated, and parts continue with the old version. Ad hoc changes , i.e. changes performed as part of the workflow itself, are the topic within ADEPT flex [23]. While this is important, our work deals with an evolution of the specifications driven from outside the running workflow instances. This is the typical case for planned workflows that are specified and installed by a workflow administrator. Approaches to transform running instances of an old ....

....it in the interleaved case is allowed, too. Note that the argumentation relies heavily on the fact that query transactions only read data, while updater transactions only write it. This precludes workflows that modify their own specification as they are investigated, e.g. in ADEPT flex [23]. If there are n queries and m committed updaters, O(nm)modificationsof commit lists are performed. O(n) accesses are necessary even in the original protocol (Def. 5) to initially create the commit lists. As we can assume that the workflows always outnumber the administrative transactions by ....

....fully understand the concepts. At the moment, there are more than 200 workflow products commercially available [24] and many organisations are introducing workflow technology to support their business processes. It is widely recognised that workflow management systems should provide flexibility [7 9, 12, 16, 21, 28, 33, 36, 37, 47, 56]. However, today s workflow management systems have problems dealing with changes, e.g. new technology, new laws, and new market requirements may lead to (structural) modifications of the workflow process definition at hand. In addition, ad hoc changes may be necessary, e.g. because of ....

....between some relevant approaches. Expressiveness: The need for a flexible and expressive modelling of process control flow, together with the ability to define new control flow dependencies, has been recognized in the last few years in the field of workflow management (see, for instance, [JB96, JH99, RD98]) but, in our opinion, it has been somewhat neglected in the related area of SPM. In spite of the very nature of SPs (which involve a loose control and a high degree of collaboration) most of existing approaches lead to very prescriptive models which do not conform to the way in which software ....

....The techniques used in this paper, i.e. workflow graphs [19, 20] and workflow nets [2] focus on the process structure. The structure of a workflow defines the way of execution, scheduling, and coordination of workflow tasks. Various approaches to workflow modeling can be found in literature [2, 4, 7, 9, 12, 13, 16, 18, 19]. Most workflow management systems use a proprietary workflow language. Despite the standardization efforts of the Workflow Management Coalition [13] a lingua franca is still missing. The specification of Interface 1 WPDL is ambiguous (no formal semantics is given) and its expressive power is ....
