最近提出了开放式出处模型（OPM）作为工作流源信息的交换框架。在本文中，我们展示了如何将工作流存储库的NRC数据模型映射到OPM。我们的映射包括在执行工作流程中复杂数据流的功能；在存储库中的不同工作流相互调用；以及在出处信息中对复杂数据结构的子值的跟踪。由于已正式指定了NRC数据流模型，因此我们的映射也可以正式指定；特别是可以自动化。为了促进此规范，我们提出了基本OPM的改编的理论形式化。
The Open Provenance Model (OPM) has recently been proposed as an exchange framework for workflow provenance information. In this paper we show how the NRC data model for workflow repositories can be mapped to the OPM . Our mapping includes such features as complex data flow in an execution of a workflow; different workflows in the repository that call each other; and the tracking of subvalues of complex data structures in the provenance information. Because the NRC dataflow model has been formally specified, also our mapping can be formally specified; in particular, it can be automated. To facilitate this specification, we present an adapted set-theoretic formalization of the basic OPM .
