Abstract To achieve knowledgesharing in collaborative product development, based upon open standards, a mechanism to implement the feature and Web servicebased sharing of engineering knowledgebase is proposed. In this mechanism, engineering database or expert knowledge acts as basic resources to construct engineering knowledgebase by the rulebased method, then the knowledgebase is wrapped and exposed to outside by Web services. Meanwhile, a method for part model transforming among heterogeneous Computer Aided X (CAX) systems is presented, which is the featurebased approach by which part models are transformed into platformindependent eXtensible Markup Language (XML) representations. Afterwards, based upon the publishing, finding and sharing approach of Web service, customers can search and choose appropriate Web services and send the XML representations of part models as inputs to gain relevant knowledge to evaluate part models, realizing efficient knowledgesharing.
