Business process management (BPM) and service-oriented architecture (SOA) are currently hot topics both in information technology industry and information systems research community. It is useful to know the processes within the collaborating enterprises to be able to establish the cooperation. For this purpose different process models have to be exchanged or integrated within the collaborating enterprises. It is, however, only in a few cases that the collaborating enterprises use the same business process modeling techniques and tools which allow an uncomplicated exchange of the models. But even within the same tools process information can get lost during the mapping between the graphical objects of a business process and its code-representation. The standards in these areas are still incomplete, software product families are incompatible and the
market is in turbulent state. This paper focuses on the possible approach of use and integration of business rules in a processoriented way, its advantages and limitations. The following paper analyses the mapping between BPMN and BPML, highlights the information losses and points out possibilities for further improvement.
