Levi - A workflow engine using BPMN 2.0

Abstract

Increasing benefits of business process automation and information technology (IT) based governance encourage organizations to model and manage their day to day business activities using business process management systems, in order to achieve increased efficiency and productivity. Many business process languages, such as Business Process Execution Language (BPEL), use a programming oriented view in process modeling as opposed to human oriented view. Recent standardization of Business Process Model and Notation version 2.0 (BPMN 2.0) provides a way to support inter-operation of business processes at user level, rather than at the software engine level. Wide adoption of the BPMN 2.0 standard is limited by the lack of runtimes natively supporting BPMN 2.0. In this paper we discuss about Levi, a cloud-ready BPMN 2.0 execution engine built using the core concurrent runtime of Apache based open source process engine ODE (Orchestration Director Engine), which executes BPMN 2.0 processes natively. © 2013 Springer-Verlag.
