Abstract: A method to realize knowledge sharing in the whole process of product based on ontology is proposed. The hierarchical denotation of product knowledge is demonstrated by means of ODLBKIF and the described language based on aspect knowledge. Furthermore, in virtue of aspect knowledge, the domain knowledge reasoning method and the communication mechanism is explained and the sharing knowledge architecture of product process is built. Finally, a valid example is presented to demonstrate the validity and practicability of the study.
