  abstract = {Dynamic evolution of workflow models due to process (re)engineering
	activities and dynamic changing situations of the real process is
	one of the most important challenges in workflow management. In this
	paper, we present an approach for the management of evolving workflow
	specifications which copes with the evolution of a workflow schema
	and the dynamic modification of workflow instances. The approach
	is based on the integrated modeling of workflow schema and instance
	elements, the separated definition of {"}what to do{"} and {"}how
	to do{"} in the workflow schema, late binding of workflows at run-time,
	and the versioning of the workflow schema. On this basis, we support
	lazy, eager, and selective propagation as well as local customization
	of instances and their upward propagation. Furthermore, we address
	the problem of managing consistent configurations of the versioned
	entities of a workflow schema. In our workflow-specific versioning
	approach, the consistency of the workflow configuration is guaranteed
	and hence the version mechanism is transparent to the user.},
