This paper presents a plausible mapping between the adopted UML Profile for EDOC systems and one of the submissions to the OMG’s Request for Proposal for a Workflow Process Definition Metamodel. Then, given that the proposed by DSTC Workflow Process Definition Metamodel does not consider the specification of events therefore in this paper it is suggested a new workflow process definition metamodel that include these aspects with a clear separation of the data and event oriented control flow dependencies and that is compatible with the UML Profile for EDOC systems. Furthermore, in order to build the proposed in this paper workflow definition metamodel as an UML profile, the new workflow metamodel is derived (stereotyped) from the UML 1.4 Activity Graphs. To introduce a representation that be computationally interpretable by a workflow engine a textual notation is introduced to represent a workflow process definition coherent with the proposed Workflow Process Definition Metamodel. As a proof of concept a simple prototype of a workflow engine able to interpret the textual representation of the workflow process definition was implemented in the Java language.
