Towards Semantic Integration of XML-based Business Process Models

This paper discusses the applicability of schema integration methodology for the integration of XML Schemas for business process modelling. This methodology builds upon the assumption that the integrated schema has to support queries and updates on all underlying local schemas. The heterogeneous schemas of Business Process Execution Language for Web Services (BPEL4WS) and Petri Net Markup Language (PNML) are used as an example to illustrate potential problems of integrating semantically related models. We identify schema integration and domain modelling as two areas of research that need to be balanced in order to specify integrated schemas.
