Abstract
Workflows are based on different modelling concepts and are described in different representation models. In this paper we present a meta model for block structured workflow models in the form of classi- cal nested control structure representation as well as the frequently used graph representations. We support reuse of elementary and complex ac- tivities in several workflow definitions, and the separation of workflow specification from (expanded) workflow models. Furthermore, we pro- vide a set of equivalence transformations which allow to map workflows between different representations and to hange the positions of control elements without hanging the semantics of the workflow.
