newYAWL : achieving comprehensive patterns support in workflow for the control-flow, data and resource perspectives

Abstract

The Workflow Patterns provide a conceptual foundation for the control-flow, data and resource perspectives of process-aware information systems (PAIS). In this paper we present newYAWL, a reference language for PAIS based on the workflow patterns. newYAWL radically extends previous work undertaken on the YAWL language and provides a comprehensive formal description of how the complete set of workflow patterns can be realized and integrated in the context of an operational PAIS. 1
