On the transformation of control flow between block-oriented and graph-oriented process modelling languages

Much recent research work discusses the transformation between different process modeling languages. This work, however, is mainly focussed on specific process modeling languages, and thus the general reusability of the applied transformation concepts is rather limited. In this article, we aim to abstract from concrete transformations by distinguishing two major paradigms for representing control flow in process modeling languages: block-oriented languages (such as BPEL and BPML) and graph-oriented languages (such as BPMN, EPCs, and YAWL). The contribution of this article are generic strategies for transforming from block-oriented process languages to graph-oriented languages, and vice versa.
