Modeling and Constructing a Metadata Repository for Wfmc's Workflow Minimum Model Using Omg/mof

Workflow Management Systems have been increasingly used in companies to automate organizational processes. To allow the integration of those systems, the Workflow Management Coalition (WfMC) defined the Workflow Reference Model. The Object Management Group (OMG), looking for the standardization of workflow management systems in the context of its objectoriented architecture, had also defined a standard based on WfMC's standards, called the Workflow Management Facility (WMF). However, process definitions, that are the representation of the organizational processes, have not been standardized by OMG yet, besides its major role in the context of workflows. In this paper it is described the representation of WfMC’s model to represent process definitions, called the Minimum Metamodel, using UML diagrams. From this representation, using the dMOF tool, it is constructed a repository of metadata that represents the minimum metamodel according to OMG’s Meta Object Facility (MOF), the standard for representing metamodels in the context of OMG’s OMA architecture. Finally, it is presented an representative business example that was modeled and inserted on the repository to verify its functionality. It is argued on the paper that this approach decreases the complexity of workflow management systems and allows a more efficient use and reuse of process definitions.
