Abstract: A metamodelbased knowledge modeling method was proposed, which provided unified knowledge description and supported convenient knowledge management system implementation. Objectoriented technique was used to define information objects and knowledge objects within the product design, including their attributes, associations and operations. Information objects were obtained to reveal relationships among information entities by abstracting characteristics of project management information and product design information. Knowledge objects were achieved by connecting the relevant information objects. The knowledge map could be built through association definition between information and knowledge objects, and then realized navigation of dominance knowledge and accumulation of recessive knowledge. The processoriented knowledge acquisition method was presented, as well as the information objects and knowledge objects were enriched with process progressing. Finally, the application of the proposed method in ProNet project was discussed.
