“…Distributed and decentralized process execution becomes increasingly important and, consequently, many such approaches demonstrate the relevance of this research (cp. [6] for a brief overview). A first possible solution for distributing the control flow of a process is to change the service granularity.…”

The decentralized execution of business process instances is a promising approach for enabling flexible reactions to contextual changes at runtime. Most current approaches address such process distribution by physical fragmentation of processes and by dynamic assignment of resulting static process parts to different business partners. In order to enable a more dynamic segmentation of such responsibilities at runtime, this paper proposes to use process runtime migration as a means of logical process fragmentation. Accordingly, the paper presents a general migration metadata model and a corresponding basic privacy and security mechanism for enhancing existing process models with the ability for runtime migration while respecting the intensions and privacy requirements of both process modelers and initiators. The approach is conceptually evaluated by applying it to WS-BPEL processes and comparing the results to the general concept of process fragmentation.

The increasing success of wireless technologies is sustaining the diffusion of mobile information systems, but the youth of the underl3äng technology and its peculiar characteristics are impacting the development of such systems. For example, the execution of business processes in such a context must cope with the variable and fluctuating bandwidth available to the different devices. This leads the designer to stress the independence of each actor ~ by minimizing interactions and knowledge sharing-to increase the reliability of the whole system. To this end, the paper proposes a rigorous approach for partitioning the execution of BPEL workflows on sets of portable devices, that is, the infrastructure of mobile information systems. The approach abstracts BPEL processes into attributed graphs and uses a graph transformation system as rules to split single workflows into meaningful sets of related processes. The paper presents such rules and exemplifies them on a case study in the cultural heritage domain.

Model transformations, like refinement or refactoring, have to respect the semantics of the models transformed. In the case of behavioural models this semantics can be specified by transformations, too, describing an abstract interpreter for the language. Both kinds of transformations, if given in a rule-based way, can formally be described as graph transformations.In this paper, we present executable business processes, their operational semantics and refactoring, as an example of this fact. Using results from graph transformation theory about critical pairs and local confluence, we show that our transformations preserve the semantics of processes. The analysis is performed by means of the graph transformation tool AGG.
