A semantic Web based model for product cooperative design

A semantic Web based model for product cooperative design is proposed by enabling engineering knowledge to be published, discovered, reused, and integrated. Three features of the model are described in detail. The first is the tools for Web design, which enable a design process to be published as a service and then to be reused as a design resource in other design processes; the second is the ontology of design resources, which helps the implementation of intelligent retrieval by semantic inference; the third is design workflows, which enable designers to construct complex design with the existing simple design instances.
