“…Generally, self-healing techniques, like the backup service we suggest, and task migration support, like the presented delegation service are indispensable when executing mobile tasks in the large scale while targeting at a high user acceptance at the same time. Existing approaches addressing respective aspects in the context of process-aware information systems again focus on BPEL as execution language [13], [23], [24]. Several approaches exist integrating entailment constraints with business process execution [9], [25]- [27].…”

Abstract-The computational capability of smart mobile devices increasingly fosters their prevalence in many business domains. Along this trend, process management technology is going to be enhanced with mobile task support. However, tasks executed stationarily so far cannot be simply transfered to mobile devices. For the latter purpose, we developed an approach within the MARPLE project enabling mobile and robust task execution in the context of business processes. In particular, this approach provides self-healing techniques that relieve mobile users from manually handling errors (e.g., lost connections) during mobile task execution. In this paper, we extend the collaboration facilities of our approach by adding entailment constraints to mobile task management. In the context of a business process, for example, two tasks may have to be executed by the same (mobile) user. Related research on integrating such constraints with business processes has received growing attention recently. However, realizing entailment constraints in the context of mobile processes and tasks raises additional issues, which must be probably integrated with the mentioned error handling techniques. We present fundamental entailment constraints supported by our approach and discuss how they can be realized in a robust and flexible manner. In particular, this will significantly enhance mobile task and process support in next generation information systems.

As described, combining real-time data and domain knowledge raises additional challenges for mobile process management.…”

“…However, context-awareness is restricted in the sense that execution can only be switched between pre-configured process variants when the context is changing. Generally, approaches allowing to switch between pre-configured process variants can be found in other projects as well [18,16]. However, the fusion of real-time data and domain knowledge with mobile processes has not been considered in a suitable manner yet.…”

Ubiquitous computing is considered as enabler for linking everyday life with information and communication technology. However, developing pervasive and mobile applications that provide personalized user assistance still constitutes a challenge. Mobile application scenarios are diverse and encompass domains like healthcare, logistics, and sales. For their support two fundamental technologies with increasing maturity are emerging: development frameworks for mobile devices and lightweight process engines. Their integrated use, however, is in a rather premature state. Generally, the use of a process engine for supporting mobile collaboration raises many challenging issues. This paper picks up some of these challenges and shows how we have coped with them in the MARPLE project. MARPLE targets at a tight integration of process management technology with mobile computing frameworks in order to enable mobile process support in advanced application scenarios. We give insights into the MARPLE architecture and its components. In particular, we introduce the MARPLE process engine, which enables lightweight as well as flexible process support on mobile devices. This will be key for mobile user assistance in advanced application scenarios.

“…Similarly to ours, their approach is also motivated by information flow control, but is restricted to acyclic workflows. There are also other approaches to fragmentation, such as that by Zaplata et al [43], which instead of partitioning the composition, assign different execution paths to nodes in the distributed enactment environment. Of course, after assigning activities to fragments using some criteria, the actual work of creating and deploying executable fragments involves many technical details and is very dependent on the composition language.…”

A sharing-based approach to supporting adaptation in service compositions

Data-related properties of the activities involved in a service composition can be used to facilitate several design-time and run-time adaptation tasks, such as service evolution, distributed enactment, and instance-level adaptation. A number of these properties can be expressed using a notion of sharing. We present an approach for automated inference of data properties based on sharing analysis, which is able to handle service compositions with complex control structures, involving loops and sub-workflows. The properties inferred can include data dependencies, information content, domain-defined attributes, privacy or confidentiality levels, among others. The analysis produces characterizations of the data and the activities in the composition in terms of minimal and maximal sharing, which can then be used to verify compliance of potential adaptation actions, or as supporting information in their generation. This sharing analysis approach can be used both at design time and at run time. In the latter case, the results of analysis can be refined using the composition traces (execution logs) at the point of execution, in order to support run-time adaptation.
