The paper at hand presents a research prototype for using a meta-modelling tool in the context of business process modelling. The prototype has been part of an e-commerce-related project and implements the mapping of business process models to workflow schemata. A meta-modelling tool has been used for implementing a modelling tool and the mapping. The analysis of the mapping is based on finding equivalent concepts in the source (MEMO-OrgML) and the target language (XPDL). Features which are not available in the source language have been added using special language elements. The paper also presents the idea of a generic mapping approach. Mappings from business process models to other process-oriented representations can be realised. The realisation of these mappings is similar to our approach. We will extend our tool with respect to support different target languages like BPEL4WS. The meta-modelling tool MetaEdit+ has been used for the prototypes.
