Aimed at the requirements of knowledge representation and integration in product lifecycle, a framework of product knowledge integration based on middle-layer was proposed. Using the techniques of ontology, the framework has the abilities of explicit definition of semantics, uniform representation and dynamic integration of product knowledge. In the meta-ontology layer, relationship primitives in ontology are defined to provide a generic representation method of ontology. In the ontology layer, meta-ontology is extended to share ontology, domain ontology, process ontology and application ontology to support the collaborative definition and the integrated mapping of ontology. In the knowledge layer, corresponding logical structures are provided for the structured and standardized management of knowledge instances, and the methods of using Web ontology language(OWL) for formal representation are given. The application of a shock absorber demonstrated that the approach can improve the product data management(PDM) system of integrating knowledge.
