To realize the equal sharing and full use of manufacturing resource, aiming at the convergence characteristics and dynamic changing behaviors of the distributed and stochastic manufacturing resources, according to the thought of peer-to-peer (P2P) and the Chord protocol, a distributed manufacturing resource sharing system model is proposed, making logic sub rings by the type of resources and the logic main rings by the super nodes. The relay of the resource rings and the convergence of different types of resources for application are completed by super nodes. The description template of the manufacturing resources and the Meta data model relating to the search keyword sets from the template are designed. The indexing process of the resources based on Meta data model and the hierarchical trust mechanism of the sharing system are elaborated; finally, an instance of the sharing system prototype is given.
