Building a repository for workflow systems

Workflow technology is becoming the key technology for business process modeling, reengineering and automating. During the workflow specification, enactment and administration, there may appear various types of metadata about workflow specifications and instances. A repository manager is, therefore, necessary to store and manage these metadata. In this paper, a workflow metamodel is proposed first. Then the requirements of repository support for workflows are explored and analysed. Based on the requirements, an object oriented design for the repository manager is presented.
