Abstract

We present a formal technique for safe distribution of workflow processes described declaratively as nested Dynamic Condition Response (DCR) Graphs and apply the technique to a distributed healthcare workflow. Concretely, we provide a method to synthesize from a nested DCR Graph and any distribution of its atomic events a set of local process graphs communicating by shared events, such that the distributed execution of the local processes is equivalent to executing the original process. The technique extends our recent work on safe distribution of non-nested DCR Graphs applied to cross-organizational case management. The main contributions of the present paper is to adapt the technique to allow for nested processes and milestones and to apply it to a healthcare workflow identified in a previous field study at Danish hospitals. We also provide a new formalization of the semantics of DCR Graphs which highlights its declarative nature.
