Extended Workflow Flexibility using Rule-Based Adaptation Patterns with Eventing Semantics.

Abstract

Abstract: In several industry scenarios, an existing reference workflow often has to be adapted according to specific context factors, which might even change at runtime. The involved change operations are however usually restricted to simple constructs like task deletion or insertion. Existing approaches lack the explicit consideration of eventing paradigms for modeling reactive parts of aworkflow and combining them with context-awareness. In this paper, wepresent amaintenance service delivery usecase and showhow hierarchical context rules tailor the workflowtochanging data contexts. We propose to extend existing basic change operations with apattern catalogue that especially captures event-based adaptation semantics for modeling languages like BPMN2 and show how apart of our solution was implemented in jBoss Drools. 1
