Abstract: Data sharing is the key technology foundation for the value of industrial data and the development of industrial Internet innovation.Based on the comparative analysis of resource organization and information interconnection in traditional Internet,German Industry 4.0 and US IIC architecture,a data sharing mechanism based on the identification and resolution system of industrial internet was proposed,including two core parts:application data model and information service model.In the application data model,the concept of recognizable digital objects was proposed,and the description methods of various types of data produced by industrial manufacturing were defined.For the information service model,a system architecture and service aiming for transmitting Identifiable Digital Objects (IDO) were raised efficiently.By identifying the core elements of physical resources for manufacturing,the proposed mechanism defined the digital description language of physical resources for manufacturing and established an efficient and standardized data acquisition,storage,access and release approach based on the identification and resolution system of industrial Internet,which could solve the problem of information interaction within the manufacturing enterprise or between enterprises,and give full play to the application value of industrial data in the manufacturing industry.
