Abstract in another language

Designing systems for inter-organizational process execution is not trivial and is affected by challenging issues due to the lack of a central coordinating authority. For this reason, current approaches connect to peer-to-peer architectures such as blockchains to synchronize all process participants upon a secure infrastructure. However, instead of integrating existing workflow management systems (WFMS) into decentralized infrastructures, a common strategy is to fuse the process world with the blockchain world by (re)implementing particular WFMS functions as smart contracts. Consequently, these approaches cannot encompass the functionality of mature WFMSs. We address this deficiency by introducing an abstract middleware layer that strictly decouples process management concerns from issues regarding the secure synchronization of decentralized WFMSs. This middleware then connects process engines with appropriate secure synchronization protocols, enabling (i) easy interchange of these key concepts and (ii) employment of existing WFMSs. Consequently, collaborations can leverage, for example, matured organizational policy management and collaboration-wide personalized work lists. We evaluate the feasibility of our approach with dpex, an open-source implementation, and its integration into a real-life use case.
