Secondly, the knowledge expression based on ontology is introduced. UML model for knowledge capture is established to find suitable knowledge. The knowledge capture formalization is established for the knowledge reuse. At last, the integration framework of knowledge requirement and knowledge reuse is constructed with a component, which includes the knowledge capture, knowledge requirement and knowledge reuse. The knowledge can be reused for collaborative design.
