An Extensible Workflow Modeling Model Based on Ontology

This paper proposes an extensible workflow modeling model based on ontology through analyzing the architecture and generic knowledge of workflow modeling component. The paper specially gives the composition principle of extensible workflow modeling model and proposes the formal description of workflow modeling ontology. At last this paper gives the composition algorithm and an example which uses this workflow modeling model. The practice proves that this model has good extensibility, and can meet most of the users´ requirements.
