Based on RP, the web-service platform architecture of bionic manufacturing was proposed to provide the service of networked bionic manufacturing with service publication. According to B/S hierarchical structure model, the four-layer architecture was constructed. It includes user layer, service layer, semantic layer and data layer. The description meta-model of web-service was constructed based on the manufacturing ontological knowledge. The dynamic connection between two collaborative enterprises and their manufacturing condition were described with enterprise class, process class, resource class, enterprise-alliance class, project class and strategy class. The information flow of web-service was detailedly described to show the service process of bionic manufacturing.
